Japanese students have usually about 1.5 month vacation in Summer ( unfortunately, they have lots of homework,too…).
From last Saturday, they are in their vacation, so there are many festivals in several place. Around me, there were a few festivals last weekends.
Anyway, speaking to Japanese summer festivals, to summer festivals in japan, Fire works (hanabi) is inextricable.
I think the Japanese hanabi performance is top level in the world. I really hope you can see it someday!!!
