Essential local emergency phrases
Show this screen to first responders, hotel staff, or passersby if you cannot speak the local language during an emergency.
Common scam patterns
- Nightlife touts / bottakuri over-billing. In nightlife areas (Noge, Isezakicho), street touts may lead you to bars that present hugely inflated bills; touting is illegal but happens after dark. Tip: Never follow a street tout into a bar; choose venues with posted prices. If threatened over a bill, call police.
Major transport hubs
| Hub | Type | Risk | Advice |
|---|---|---|---|
| Yokohama Station | train_station | 20/100 | Standard awareness in rush-hour crowds; the risk is low. |
Area notes
- Noge / Isezakicho nightlife. Lively nightlife where street touts and over-billing are the main risk after dark; daytime areas like Minato Mirai and Chinatown are very safe.
- Overall. Yokohama is very safe with very low street crime; the main caution is nightlife over-billing, not violence or theft.
