Natural Hazard Preparedness and the Specific Frictions Tourists Face

Japan Safety Beyond Low Crime to Earthquake and Typhoon Readiness

You are standing in Shinjuku Station at 8:15 AM with 3.6 million other commuters when your phone screams a high-pitched alert you did not set. The screen reads J ALERT in English. Earthquake incoming, 15 seconds. This is the moment that separates a prepared traveler from a panicked one.

Japan has a crime index of 23.1 on Numbeo's scale. London scores 53.8. New York scores 49.2. Paris scores 57.4. Your risk of theft sits at 1.2 per 100,000 people (UNODC, 2022). Your risk of homicide sits at 0.2 per 100,000. These numbers mean you can walk alone at 2 AM in almost any neighborhood without looking over your shoulder. But that low crime baseline is not the full safety picture. The real risks in Japan are geological, meteorological, and social. This page tells you what to prepare for.

Earthquake Readiness: the Alert System and What to Do

Japan's J Alert system launched in 2007. It delivers warnings through TV, radio, outdoor speakers, and area mail to your phone. You get between 5 and 30 seconds of lead time before strong shaking arrives. Those seconds are not for panic. They are for action.

Your Moves Indoors

Drop to the floor. Take cover under a sturdy table. Hold onto its legs until the shaking stops. Stay away from windows, heavy furniture, and gas appliances. Do not use elevators. If you are in an elevator when the alert sounds, press every floor button and get out at the first opening.

Every building constructed after 1981 must meet Japan's shin-taishin seismic standards. These buildings are designed to withstand intensity 6+ to 7 on the Japan Meteorological Agency scale. If your hotel or guesthouse was built after 1981, you are in the safest structure available. If you are in an older building, identify your nearest exit and a table to get under before you unpack.

When The Shaking Stops

Gas leaks and fires cause the majority of post-quake injuries. Turn off any gas appliances you can reach. Check for fallen objects blocking exits. Expect aftershocks within minutes. Do not light matches or lighters until you are certain there is no gas leak. If you are near the coast and the shaking was strong or sustained for longer than 30 seconds, move to high ground immediately. Do not wait for an official tsunami warning.

Typhoon Season: Transport Shutdown and What to Do

Typhoon season runs June through October, with the peak in August and September. The JMA issues track forecasts 72 hours in advance. These forecasts are reliable enough to make decisions on. The failure case for a typhoon is getting stuck in a city when all transport stops.

Shinkansen and local trains suspend operations when sustained wind speeds reach 25-30 meters per second. Flights are cancelled at wind speeds of 15-20 m/s. Expressways close at 20 m/s. These closures are operator decisions and happen with 12 to 24 hours notice. Theme parks and tourist sites close at the discretion of the local municipality. When a typhoon is forecast, check your operator's website the evening before. JR East, JR West, and JR Central post English-language service suspension updates. If your Shinkansen is cancelled, your ticket is valid for the next available train or fully refundable. Do not line up at a ticket counter. Use the operator's app or website to rebook.

Riding It Out

During the storm, stay in your accommodation. Convenience stores stock emergency supplies: water, onigiri, and instant noodles. Stock up before the storm hits, because shelves empty fast. The storm passes within 12 hours. After it clears, transport resumes within 2 to 4 hours. Build one buffer day into your itinerary during August and September.

The Specific Frictions: Tattoos, Trash, and Lost Items

The crime rate is low. The social rule density is high. Two frictions will affect your daily experience more than any earthquake or typhoon.

Tattoos And Public Baths

Most onsen, public baths, and hotel pools ban visible tattoos. This applies even to small designs. Some facilities in tourist-heavy areas like Hakone or Beppu have relaxed the rule, but the majority have not. If your tattoo is small enough to be covered by a single skin-coloured patch, use one. If it is larger, search for 'tattoo friendly onsen' in the city you are visiting. Ryokan and super sento chains like Ooedo Onsen Monogatari have tattoo-friendly branches. You do not need a tattoo to enjoy a public bath, but if you have one, plan for this friction before you arrive.

Carrying Your Trash

Public trash cans are virtually non-existent in Japan. This is a deliberate policy following the 1995 sarin gas attacks. You carry your rubbish for hours. A single convenience store bag accumulates wrappers, bottles, and used napkins over a day of walking. The solution: carry a small, sealable bag in your daypack. Dispose of trash at your hotel room, at convenience stores after you buy something, or at station trash cans located inside the ticket gates. If you are eating street food in Dotonbori or Nishiki Market, the vendor who sold you the food will take back the packaging. Ask by pointing.

Koban Police Box For Lost Items

Lost something? A phone, a wallet, a camera? Go to the nearest koban. These small police boxes sit at major intersections and train stations across every city. You do not need to speak Japanese. Walk in, show a photo of the item on your phone, and say 'sumimasen, nakushimashita' (excuse me, I lost something). The officer will fill out a report. If the item was turned in, you get it back. Japan's lost and found system returns over 80% of lost wallets and phones. The koban is also where you report a theft, though theft is rare. Do not hesitate to walk in. They expect tourists.
