Add for the season and route
Summer requires breathable clothing, sun protection and a compact rain layer. Spring and autumn need adaptable layers. Winter packing changes sharply between Tokyo, Hokkaido, Sea of Japan snow regions and Okinawa.
| Trip | Add | Check |
|---|---|---|
| Spring | Layers, light rain shell | Region-specific bloom weather |
| Summer | Breathable clothes, hat, hydration | Rain and heat alerts |
| Autumn | Light knit, rain layer | Temperature change by elevation |
| Winter/snow | Insulation, grip and route gear | Local snow conditions |
Power and medication need extra attention
Japan uses 100V electricity with Type A and B sockets and different grid frequencies by region. Many modern chargers accept 100–240V, but check the label; an adaptor does not convert voltage.
Japan regulates some medicines and quantities differently. Travellers with prescription or controlled medication should check official Japanese requirements well before departure and carry supporting documentation.
Luggage and onsen details
Use a compact overnight bag when forwarding the main suitcase. Keep valuables, medicine and the next day’s clothing with you because delivery can take more than one day on some routes.
Onsen and public baths usually provide washing facilities and expect guests to wash before entering the bath. Tattoo policies vary by property, so check in advance rather than assuming.

Frequently asked questions
What plug adaptor do I need for Japan?
Japan uses Type A and B sockets at 100V. Check each device’s voltage range; a plug adaptor alone does not convert voltage.
Should I take a large suitcase to Japan?
Smaller luggage is easier on trains and in compact rooms. Luggage forwarding lets you send a larger case while carrying an overnight bag.
Can I bring my prescription medication?
Rules depend on the substance and quantity. Check official Japanese import requirements well before travel and obtain any required permission.
