Before looking at the weather, there are a few cultural norms and logistical realities to keep in mind when packing your suitcase.

1. The “Slip-On Shoe” Rule: You will take your shoes off a lot—at temples, traditional izakayas (pubs), ryokan (inns), and even store fitting rooms. Pack comfortable walking shoes that are easy to slip on and off. And remember to pack nice, hole-free socks!

2. Mind the Cultural “Dress Code”: Japanese fashion is highly trendy but leans conservative. While shorts and short skirts are perfectly fine, plunging necklines or exposing your shoulders and cleavage are less common. When visiting shrines and temples, modest clothing is highly recommended as a sign of respect.

3. Athleisure isn’t Everyday Wear: While common in the West, wearing tight yoga pants or leggings as everyday trousers isn’t widely done in Japan unless you are actively running or hiking. Locals typically layer them under shorts or skirts.

Spring is one of the most beautiful times to visit Japan. From late March through April, cherry blossoms spread across much of the country, bringing hanami (flower-viewing) picnics and scenic walks to parks, riversides, and temples.

Temperatures gradually warm through the season, though mornings and evenings can still feel chilly, especially in March and early April. Layering is recommended, with light jackets and sweaters that are easy to add or remove.
