Should I bring a lot of heavy winter clothes?

No. Unless you are going to Hokkaido, a heavy coat is enough. You can buy cheap, high-quality thermal layers at any Uniqlo in Japan.

Is it okay to wear shorts in Japan?

You can wear shorts in the summer, but many locals prefer trousers or skirts. Avoid overly revealing clothing if you plan on visiting traditional shrines.

Why is a hand towel necessary?

Many public restrooms in Japan do not have paper towels or hand dryers. Carrying your own small towel is a standard local habit.

What to pack for Japan by season

Dress in layers to adapt to Japan's distinct seasonal shifts and high humidity. Always prioritize comfortable, slip-on shoes because you will be taking them off multiple times a day.

Spring (March–May). Bring a medium-weight jacket for cool mornings. Layer with light sweaters or long-sleeve shirts. Temperatures range from 10°C to 20°C.
Summer (June–August). Pack moisture-wicking fabrics and loose clothing to combat high humidity. Carry a small hand towel and a folding umbrella, as rain is frequent.
Autumn (September–November). Similar to spring, a versatile jacket is essential. Add a light scarf for November, as temperatures drop quickly once the sun goes down.
Winter (December–February). Pack a heavy down coat, thermal base layers, and gloves. Japan's indoor heating is intense, so ensure your outer layer is easy to remove.
Footwear strategy. Wear broken-in walking shoes that are easy to slip on and off. Avoid high-maintenance laces unless you want to hold up the line at every temple or restaurant.
