What to Wear in Osaka in Spring: Clothes, Outfits and Accessories
When packing for March, it's advisable to include warm clothing like sweaters or cardigans, as well as thick pants or tights to pair with skirts. At the beginning of the month, a down coat or thick wool coat, along with gloves and a scarf, will help keep you cozy.

May is considered the prime time to visit Osaka. From the middle to the end of the month, you can bid farewell to your coat, and for most days, a single cardigan or long-sleeved shirt will suffice.
