Do I need an outlet adapter?

Yes, Japan uses Type A and B plugs (two flat pins). If you are coming from Europe or the UK, you definitely need a plug adapter.

Is it rude to wear shorts in Japan?

Not inherently rude, but locals generally dress more formally than in the US or Australia. You will stand out as a tourist, and some high-end restaurants may have dress codes.

How much luggage should I bring?

Bring as little as possible. Navigating crowded train stations with large suitcases is exhausting. Aim for one medium-sized checked bag or a large backpack.

How to Pack for Japan's Changing Seasons

Japan’s climate varies wildly from sub-zero winters to humid, tropical summers. Pack a lightweight waterproof shell for year-round utility and focus on a modular layering system that allows you to add or subtract insulation based on the specific month of your visit.

Audit the climate by month. March-May (Spring) requires a light jacket and sweaters. June-August (Summer) requires moisture-wicking fabrics and high UV protection. September-November (Autumn) mimics spring layering. December-February (Winter) requires a heavy down parka, thermal base layers, and gloves.
Prioritize slip-on footwear. You will be taking your shoes off constantly—at temples, traditional restaurants, and guesthouses. Choose comfortable walking shoes that can be easily removed and put back on without complex lacing.
Use a modular layering system. Bring a base layer (t-shirt), a mid-layer (fleece or sweater), and a top shell (windbreaker or parka). This allows you to adjust quickly when moving between heated train carriages and cold outdoor platforms.
Pack for laundry access. Most business hotels and hostels in Japan have coin-operated washers and dryers. Pack only 5 days' worth of clothing and plan to do laundry once mid-trip to keep your luggage weight under 10kg.
