20 Japan Weird Laws for Tourists Every Traveler Should Learn

Planning a trip to Japan? You’re probably imagining cherry blossoms, high-speed bullet trains, and vending machines that sell… well, just about everything. But here’s something you might not expect — Japan weird laws for tourists are a real thing. And they can be… confusing. Or fascinating. Sometimes both.

Now, some of these laws are actual written rules. Others? They’re more like deep-rooted cultural expectations that, honestly, feel just as strict. Either way, what seems like normal behavior to you — say, munching a snack while walking or chatting on a phone in public — could raise eyebrows (or worse) in Japan.

Learning 20 of the Japan Weird Laws For Tourists

So before you accidentally break a rule you didn’t know existed, it’s worth taking a few minutes to learn the ropes.

This guide walks you through 20 strange, surprising, and uniquely Japanese laws and cultural rules. A mix of the official kind… and the ones that aren’t on paper, but very much enforced through side-eyes and social cues.

Let’s dive in to the list of 20 Japan weird laws for tourists.

I: Public Etiquette Laws and Rules

1. Don’t Jaywalk — Even When Roads Are Empty

Okay, so you’re standing at a crosswalk. It’s midnight in Kyoto. No cars in sight. The light is red… but there’s literally no reason to wait, right?

Wrong.

In Japan, jaywalking is more than just a traffic violation. It’s considered a sign of disrespect toward public order — and yes, even when there are no cars around. You might get a polite nod from an officer. Or, in stricter prefectures, a fine. But more commonly, you’ll just feel like that person everyone’s side-eyeing.

It’s part of the broader laws in Japan for tourists to understand: the idea that following rules, even small ones, reflects social harmony. So yeah… just wait for the green man.

2. No Talking on the Phone on Trains

This one hits differently if you’re used to loud, buzzing subway systems where personal calls blend into the background noise. In Japan? That’s a hard no.

Taking a phone call on a train — even a short one — is considered incredibly rude. Especially in the quiet zones (which exist on many long-distance and city lines). You’ll likely get a few disapproving glances… or even a quiet reminder from another passenger.

It’s not officially written in the Penal Code, but it’s part of Japanese laws to be aware of if you want to avoid sticking out in a bad way. Instead, text quietly or just wait. People on trains are generally silent, often even sleeping upright. It’s almost eerie how peaceful it is… and kind of lovely, once you get used to it.

3. You Can’t Dance After Midnight (Historically)

This one feels almost made up — like something out of a retro movie. But it’s true.

For decades, the Fueiho Law in Japan banned public dancing in clubs after midnight. The rule was originally introduced to crack down on illegal activity in post-war dancehalls… but it stuck around. Until 2015.

Even though the law was relaxed, many clubs still follow the tradition. Some cities, especially outside Tokyo, continue to restrict dancing at certain hours. It’s not that you’ll get arrested mid-twirl, but don’t be surprised if a DJ wraps things up earlier than you’d expect.

So yeah — dancing isn’t illegal now, but the cultural ghost of that law still lingers. Just one of those weird Japanese rules you might trip over (literally) if you’re not paying attention.

4. Eating While Walking is Frowned Upon

Technically? Not illegal. But practically? You’ll feel like you’re committing a small crime if you bite into a convenience store rice ball while walking down the street.

In Japan, eating while walking is considered messy and disrespectful — especially near shrines, in public transport, or on clean city sidewalks. This ties deeply into Japan’s values of cleanliness, order, and mindful consumption. Locals usually eat near where they bought the food. Even vending machines often have a little standing area beside them just for that.

So, while you can eat on the go, you might want to pause, stand to the side, and enjoy the bite. It’s part of learning the subtle yet significant laws in Japan for tourists… the ones that don’t always come with a signpost but matter just as much.

II. Hygiene and Cleanliness Laws

5. Spitting or Littering is Heavily Fined

Japan takes cleanliness seriously — like, really seriously. You won’t find overflowing bins or plastic bags flying around in the wind. In fact, you’ll barely find trash cans at all… and yet the streets are spotless.

Part of the reason? Laws in Japan for tourists (and locals too) that penalize spitting or littering, especially in designated areas like Tokyo’s Beautification Enforcement Zones. And it’s not just a gentle suggestion. In places like Shibuya or Yokohama, fines can go up to ¥50,000 for littering. Even cigarette butts count.

It’s a system that relies as much on social pressure as it does on rules. The expectation to carry your trash — and dispose of it properly later — ties into Japan’s deep cultural emphasis on waste management and civic responsibility.

So, if you’ve just left a convenience store with a snack wrapper in hand and can’t find a bin, hang onto it. You’re not being punished… you’re being trusted.

6. Public Baths Ban People with Tattoos

This might surprise you, especially if you’re coming from a place where tattoos are just… personal style. But in Japan, they carry a much heavier cultural weight — often associated with the Yakuza, Japan’s infamous organized crime syndicates.

Many public baths and hot spring resorts (onsens) outright ban tattooed guests. Even a small visible design on your ankle could get you politely turned away. It’s not because they think you’re dangerous — it’s about preserving peace and making others feel safe. Still, kind of awkward when you’re standing there in a towel.

That said, times are slowly changing. Some hot spring hotels and public swimming pools now allow tattoos if you cover them with a sticker or book a private room. You can even check in advance through the Japan – Culture Smart! site or local directories.

But yeah… if you’ve got ink, this is definitely one of those Japanese laws for foreigners to be aware of before showing up ready to soak.

III. Shopping and Money Rules

7. It’s Illegal to Resell Concert Tickets

So let’s say you scored a couple of extra tickets to a J-pop concert. Tempted to sell them on Reddit or pass them to a tourist for extra cash? Don’t.

Japan weird laws for tourists Reddit threads are full of stories like this — because it’s one of those things that feels innocent but can land you in actual trouble. Under the Ticket Resale Prevention Law, unauthorized reselling (especially at inflated prices) is a punishable offense. Police have cracked down on scalpers, even using undercover sting operations during big events.

If you can’t attend, some events offer official resale options through ticket platforms. Anything else? Risky. And not worth the potential arrest or travel complications.

Weird? Maybe. But it’s just one more layer of Japan’s legal system that operates with an intense respect for fairness and order.

8. Always Bring Cash — Some Places Don’t Accept Cards

Not illegal, but definitely surprising — Japan is still a cash-first society in many ways.

You’ll find sleek bullet trains, ultra-fast Wi-Fi, and futuristic toilets… but step into a ramen shop or small boutique, and they might shake their head at your credit card. Some places — especially outside major cities — operate entirely in cash.

So while it’s not one of the strict Japanese laws, it’s more like a non-negotiable travel tip. Carry cash. Lots of it. ATMs at post offices and convenience stores like Lawson or 7-Eleven are your best bet, especially if you’re carrying a foreign card.

And don’t forget — Japan’s tipping culture doesn’t exist. Not only is it unnecessary, but trying to tip someone can lead to confusion or awkward refusals. They might even run after you to return the change.

So yeah… have your yen, skip the tip, and maybe keep a small medicine carrying case for coins. You’ll need them.

IV. Drug and Medication Restrictions

9. Common Medications Are Illegal

Here’s where things can get… unexpectedly complicated. Medications that are sold over-the-counter in your country — like Sudafed, Vicks inhalers, or anything containing pseudoephedrine — can be completely banned in Japan.

Even prescription drugs, including Adderall or certain allergy medications, are considered controlled substances under Japan’s Misdemeanor Law and Pharmaceutical Affairs Act. Some have landed tourists in jail or deportation proceedings for simply carrying pills they legally use back home.

To avoid any issues with Japan Customs, check in advance. And carry your meds in the original packaging, with a doctor’s note and a travel protection plan if possible. Some travelers also get clearance via a “Yakkan Shoumei” — a medical import certificate required for certain drugs.

Because in Japan, even an innocent cold medicine can turn into a drug-related crime situation faster than you’d think. So yeah… don’t assume it’s fine just because it’s legal where you’re from.

10. Zero Tolerance for Marijuana (Even CBD Products)

This one’s strict. Like, no-exceptions strict.

Marijuana is completely illegal in Japan, even for medical use. Even CBD oil — if it contains any trace of THC — can result in arrest. Customs agents have detained travelers for vape pens, edibles, or oils that were totally fine back home.

What’s wild is that even residue found in luggage could be enough for a case under the Japan Penal Code. The Japanese government takes a zero-tolerance stance, and yes, that includes small quantities or even unintentional possession.

And honestly? The legal and social consequences are harsh. We’re talking prison time, massive fines, or permanent bans from the country. If you’re unsure, leave it behind. No experiment or souvenir is worth your vacation turning into a courtroom appearance.

One more thing? Even CBD beauty products can raise red flags. So double-check every ingredient list. And then maybe check it again.

V. Weird Alcohol and Smoking Laws

11. You Can Drink in Public — But Be Respectful

This one catches a lot of people off guard, especially travelers from countries where open containers in public are a big no-no.

In Japan? Drinking in public is legal. You’ll see people sipping beer under cherry blossoms during hanami season, or quietly sharing sake at a summer festival. It’s not just allowed — in some settings, it’s practically tradition.

But there’s an important catch: you’re expected to be discreet and respectful. Loud, drunken behavior? Not okay. Causing a scene? Even worse. It’s less about the law and more about social harmony — which, if you’ve picked up on the pattern by now, is kind of a running theme in Japanese cultural values.

And a quick note on alcohol content: beverages sold at convenience stores can be stronger than they look. Japanese chu-hi cans pack a punch… and sneak up on you.

So yeah, drink your beer under the stars if you want. Just don’t be that tourist.

12. Smoking in Public Can Be Illegal

On the flip side, smoking in public is one of the things that is actually regulated — heavily.

Many cities, including Tokyo and Osaka, have designated smoking areas. Step outside of them with a lit cigarette and you could face a fine, even as a tourist. And yes, that includes casual strolls with a smoke in hand. It’s treated as a public safety issue and a waste management concern.

In fact, some areas are so strict they’re called Beautification Enforcement Zones, where even holding a cigarette outside the designated area is considered a violation.

Ironically, you’ll still find cigarette vending machines pretty much everywhere. But here’s the twist — to use one, locals need a TASPO card (it verifies age). Tourists usually can’t get one, which means you’re out of luck unless you buy from a staffed shop.

It’s another one of those contradictions Japan seems to embrace: high-tech access to cigarettes… with strict public rules around using them.

VI. Transport and Driving Laws

13. No Drunk Cycling

Let’s say you’ve had a few drinks at an izakaya, and you’re thinking of casually riding your rental bike back to the hotel. Sounds harmless, right?

Not in Japan.

Under the Road Traffic Act, cycling under the influence is treated exactly like drunk driving. That means you could be stopped, fined, or even arrested — yes, for wobbling home on two wheels after a couple of beers.

It’s one of those laws in Japan for tourists that doesn’t get talked about much… until someone finds themselves in trouble. If you wouldn’t drive a car, don’t ride a bike. Use the train. Or just walk. Or sit somewhere and sober up with a vending machine coffee (they’re surprisingly good).

And no — saying “but I’m just a tourist” doesn’t help.

14. Don’t Touch Taxi Doors — They Open Automatically

This one isn’t a law, but it might as well be, considering how seriously people treat it.

In Japan, taxi doors open and close automatically, controlled by the driver. If you reach out and try to handle it yourself, it’s considered a bit rude. Not offensive exactly, just… clumsy. Like you didn’t take the time to learn even the most basic local tip.

And trust me — the first time it opens on its own, it’s weirdly delightful. Feels futuristic, even though the system’s been around for decades.

So yeah. Stand back. Let the door do its thing. It’s a small gesture that shows you’re tuned into Japanese etiquette — even if it’s your first time in the country.

VII. Technology and Surveillance

15. Don’t Fly Drones Without a Permit

Have a drone and visions of capturing the perfect aerial shot of Mount Fuji? Better read this first.

Japan has some strict drone laws, especially under the Radio Law and Aviation Act. You’ll need a permit to fly drones in populated areas — which includes most major cities, temples, and parks. And flying near airports? Completely banned.

Even hobby use is restricted. If your drone weighs over 200 grams, you’re expected to register it with authorities. And if you violate the rules, your gear could be confiscated on the spot. Or worse… you might face fines or legal action under the Japanese constitution’s tech and safety provisions.

There are designated areas where you can fly drones — often in rural zones or special parks. But even then, you’re expected to follow specific rules on altitude, time of day, and proximity to people.

Bottom line? If you’re not sure, just leave the drone at home. Or get really good at using your phone’s panorama mode.

16. Filming People Without Consent is Illegal

This one’s about privacy. And it’s serious.

In Japan, filming or photographing people without their consent — especially in sensitive areas — is illegal. That includes private spaces like bathrooms, dressing rooms, and public baths, of course. But even temples, Shinto shrines, and some attractions and tours have signage asking visitors not to film.

It’s part of the country’s broader effort to protect individual privacy and cultural integrity. Under the Penal Code and various local ordinances, violations can lead to fines or prosecution.

And it’s not just the legal side — socially, it’s seen as incredibly disrespectful. Tourists snapping selfies in places meant for reflection or worship? Not a great look.

There’s even been an increase in signage specifically in English reminding visitors to avoid filming locals without permission. It’s not paranoia — it’s just a very different relationship with technology and personal space.

So if in doubt, ask. Or better yet, soak in the moment without your phone.

VIII. Culture-Specific and Lesser-Known Laws

17. You Must Carry Your Passport at All Times

It’s easy to forget — especially if you’re out for a quick bite at a local convenience store or hopping between Hotels & Homes. But legally, if you’re a foreign tourist in Japan, you must carry your passport at all times.

Police have the right to stop and ask for ID on the spot. And no, a photo of your passport on your phone doesn’t count. If you’re caught without it, you could be detained until you prove your identity — even if everything else checks out.

This one sits firmly within laws in Japan for tourists, and it’s tied to Japan’s broader immigration and travel protection policies. It might feel excessive, but it’s part of the system.

Pro tip? Use a neck pouch or slim travel wallet and make it part of your everyday carry. It might save you from a situation that gets awkward fast.

18. No High Heels or Tripods in Certain Historic Areas

Some rules feel like they were made for ultra-specific moments — and this is one of them.

In historic districts like Kyoto’s Gion or the narrow streets around Shinto shrines and temples, you might see signs banning tripods, high heels, or even loud talking. And it’s not just a suggestion.

Why? It’s about protecting delicate stone paths and cultural landmarks. Thin stiletto heels can damage ancient surfaces. Tripods can block pathways or trip pedestrians. And speaking loudly in these places? It clashes with the whole atmosphere of reverence.

So yeah… it’s not one of the “10 laws in Japan” you’ll see on travel posters, but it’s something Japanese laws for foreigners subtly reinforce through signage and polite correction.

Honestly, it’s more about respect than punishment.

19. Gambling is Technically Illegal — But Pachinko is a Loophole

You’ll see the bright, buzzing lights of pachinko parlors everywhere in Japan. But gambling is illegal… right?

Well, sort of.

Under Japanese law, traditional gambling (like casinos or sports betting) is banned. But pachinko operates in a legal gray area — you technically win prizes, not money. Then, in a separate building nearby, you “sell” those prizes for cash.

It’s a workaround that’s so baked into the system, it’s almost comical. One of those bizarre things you’d read about in a “Japan weird laws for tourists Reddit” thread and assume is fake… but it’s not.

Still, this is one space where it’s best to watch rather than join in — especially since foreigners sometimes misunderstand the rules, and that confusion can be costly.

20. It’s Illegal to Work Without a Visa — Even Volunteering Can Be Risky

This one feels counterintuitive to a lot of travelers, especially those on long-term cultural trips. You’re just helping at a guesthouse in exchange for a bed and breakfast… so what’s the harm?

But in Japan, any work — even unpaid volunteering — without a proper visa is illegal. Under the Act on Comprehensive Promotion of Labour Policies, offering services, labor, or any kind of compensated work (even in barter form) counts as employment.

And the punishment? Detention, deportation, and even bans from reentry.

It’s one of those laws tourists don’t think to look up — and that makes it even riskier. If you’re unsure whether an opportunity crosses the line, it probably does.

So yeah, what is illegal in Japan for tourists goes way beyond obvious stuff. Even doing someone a favor might technically breach the Japan law system.

Cultural “Non-Laws” Tourists Mistake as Legal Requirements

There’s this whole category of Japanese “rules” that aren’t really laws at all… but still feel compulsory the moment you land. Are they enforced? No. But ignore them, and you’ll feel every silent stare in the room.

Let’s call them… cultural tripwires.

• Bowing Instead of Shaking Hands
  No one will arrest you for offering your hand. But in many settings, a bow is more natural and respectful — especially at temples, shrines, and formal greetings.
• Taking Off Shoes Indoors
  Homes, traditional restaurants, even some fitting rooms require you to remove shoes. Step on tatami mats with sneakers? Major faux pas.
• Not Tipping
  Not just unnecessary — tipping can actually confuse or mildly offend your server. Wages are structured differently here, and excellent service is just… expected.
• Standing on the Correct Side of the Escalator
  In Tokyo: stand on the left, walk on the right. In Osaka? Flip it. There’s no official Road Transportation Law on this… but locals follow it like gospel.
• Queue Etiquette at Convenience Stores
  There’s a designated waiting area near the register. Jump the line accidentally, and you’ll immediately feel the shift in energy. Quiet, but firm.
• No Splashing in Public Pools or Hot Springs
  There’s even a local “No Splashing” law in some resorts — more of a regulation than full law, but still observed.
• Reserved Seating Rules on Public Transport
  Priority seats are marked clearly for elderly, pregnant, or disabled passengers. Even if they’re empty, don’t sit unless it’s clearly okay.

These aren’t on any Japanese Embassy website or listed under the Japanese constitution… but break them, and you’ll definitely notice the cultural ripple.

And honestly, most of them are lovely — gentle reminders of how much Japan’s cultural tapestry is stitched together by quiet respect.

Final Thoughts

Japan is a beautiful mix of tradition, etiquette, and unexpected quirks—and yes, that includes some pretty weird laws in Japan. While most of these rules won’t impact your trip too heavily, being aware of them can make your travel smoother and more respectful.

Whether it’s about manners, noise, or strange customs, these japan weird laws for tourists offer a fascinating glimpse into what makes the country so uniquely captivating.
