Japan Packing List: Onsen, Temples and Carry-On

Build a small clothing rotation around the actual season, places and laundry access. This list is an example to adapt, not a claim that everyone needs a 22-litre bag or a fixed clothing weight.

An adjustable packing list

Wear the bulkier footwear if practical, but do not use a tiny bag as a reason to omit needed winter clothing. Snow, mountain routes and northern Japan need their own plan. Confirm laundry facilities and drying time before reducing your rotation; wash-and-dry cost is not nationally fixed. Weigh packed shoes and clothes instead of treating example gram figures as product specifications.

Temples and shoes

JNTO advises respectful dress and avoiding overly revealing clothing at temples and shrines. That is not a universal shoulders/knees/white-socks code for every site. Follow signs for the places you visit. Wear shoes you can remove where requested and carry clean socks. A spare light layer can be useful without claiming that every temple requires one.

Onsen preparation

For an ordinary bathing facility, JNTO describes washing before entering, leaving clothes and swimwear in the changing area, and keeping towels and hair out of the bath. Shoes or slippers come off before the changing room; do not recommend flip-flops on every bath floor. Venue rules, private baths and special facilities can differ.

Ask whether towels are provided, rented or sold. Take a small towel only if needed, and keep it out of the water. Check the venue’s tattoo/access rules before booking. Keep your phone and camera out of the bathing area to respect privacy. Do not promise that a national list guarantees acceptance at every onsen.

Toiletries and electrical equipment

Pack the essentials you cannot readily replace and plan optional shopping after arrival. Local shop stock and hotel toiletries are not guaranteed. Sunscreen, creams and pastes count under the applicable liquid rules; Narita’s international-departure rule is 100 ml containers in one 1-litre transparent resealable bag. Other checkpoints and special articles need their own check.

Japan uses 100V with regional 50/60Hz and TypeA plugs. Check voltage range, frequency, grounding and manufacturer instructions for each device; a plug adapter does not convert voltage and no country of purchase guarantees suitability. Power banks must meet the operating airline’s conditions.

Pack and test the bag

Keep the clothing rotation together, protect fragile items inside the bag and put checkpoint items where they can be reached. Leave space for purchases within your actual allowance. Measure external protrusions and weigh all pieces together where the airline combines weight. A compression cube reduces volume, not mass.
