In Sapporo, some fireworks can be seen in summer. These fireworks are usually held in river or parks. Thus some people go to such places to see fireworks. I didn’t go anywhere in this summer because it was hot.
However, I found I could see fireworks from my room. So I took pictures from my room. I was satisfied with them. I enjoyed this summer.
Another merit of seeing fireworks from my own room is that I don't have to be involved in rush in the venue and the nearest station. It needs patience.
