Kawaguchi
川口
Use Kawaguchi as a cheap commuter base for Tokyo: half‑day visit or overnight stay, 20‑30 min to central stations.
Kawaguchi is a densely populated Saitama city on the Arakawa River, offering low‑cost accommodation and fast rail links to Tokyo (≈23 min to Tokyo Station). Its riverside parks give a green break after city work, while most attractions are limited to shopping and local markets, so a half‑day or one night is enough.

Etiquette, safety and scams
Etiquette
- Greeting: A small bow; a handshake if the other person offers; avoid: Hugs, back slaps, loud greetings
- Names: Family name plus -san; avoid: First names unless invited; adding -san to your own name
- Paying: Put money in the tray at the register; avoid: Tipping, or leaving loose cash for staff
- Trains: Queue at the floor marks, phone on silent, ask before reclining on the Shinkansen; avoid: Phone calls, eating on crowded commuter trains, blocking doors with bags
- Escalators: Stand on the side locals use — left in Tokyo, right in Osaka; stations now ask people to stand still on both; avoid: Stopping at the top or bottom
- Shoes: Off at the step-up entrance; toilet slippers only inside the toilet; avoid: Stepping on tatami in shoes or slippers
- Shrines: Rinse hands at the basin; bow twice, clap twice, bow once; avoid: Walking down the centre of the approach, which is for the deity
- Gifts: Offer and receive with both hands; bring a small omiyage for hosts; avoid: Sets of four; cash outside an envelope
Scams and watch-outs
- Mid‑day Keihin‑Tohoku trains skip Nippori – check timetable if transferring from Narita.
- Some bus services (e.g., Keio Bus from Shinjuku) are slower (≈1 h 45 min) and cost ¥1,700.
Generally safe; stay alert on crowded trains and keep belongings secure.
