What clothes should I take to travel to Tokyo Osaka, Japan at the end of May?

Basically, just bring a short-sleeved T-shirt and a long-sleeved T-shirt plus a coat. The climate in Japan was already quite hot at the end of May. Be sure to take an umbrella. Japan's maritime climate is changeable, with sunny mornings and rainy afternoons. You must carry necessary drugs and reasonable personal dosage. Without Japanese medical insurance, it is very expensive to see a doctor in Japan. If you are worried, you can also buy an overseas travel insurance yourself. Converter, the voltage in Japan is 1 10v, so the domestic patch panel cannot be used directly, and the converter needs to be purchased separately.

I hope the beautiful month will give you a satisfactory answer and wish you a happy life!
