下星期去日本著咩衫?

I am now on my trip over Japan.
The temperature is around 18-23. not hot at all even in day time.
I think long sleeve is much better.
also you better to bring a jacket as the difference of temperature is quite big after evening. quite cold at night.

請參考以下網址, 會預告未來7天的天氣, 都好準的(本人4月尾去日本時都是參考它的):

但我覺得短袖T,短褲就唔可以啦, 一定要有長袖外套和長褲, 而波鞋就無問題, 重係好好的裝備呢!

你可以上日本Yahoo 查一查當日的天氣,它用圖案表示,所以不識日文,也明白,綱址如下
