Did you know that fireworks is the United States are only allowed on July 4th?(アメリカでは7月4日のみ花火が許可されている）
Yes, July 4th in Independence Day of the United States(独立記念日), so they enjoy seeing fireworks usually along with beautiful music for them.
In Japan, we can enjoy fireworks through the year, but in the United States you cannot do that except July 4th.
I don't know why, but I guess fireworks are one of the traditional summer events for Japanese with yukata(浴衣）.
Do you have any plans to go and watch fireworks this year? Here in Tokyo, we have big fireworks display around Sumida River(隅田川）. I have never been there to see it, but there must be lots of visitors from all over Japan at that day....
Anyway, soon this rainy season will end, so take care
