In Japan you see lots of insects flying around, and if you leave open the windows of your room for 30 minutes or so, insects will sneak into your room. This is why I don't open the windows so often. It's fall now, so the number of insects coming in is smaller, but in the summer you will bump into insects many times while you're on the bike.
When I was a kid, there was already video games and some of my friends played them after school was over, but most of the Japanese parents didn't like their kids to stay home, and told them to do some kind of outdoor activities such as sports, and my friends and I went in the woods to catch some insects like beetles.
This Ushiku Nature Park is where you can see lots of insects and plants. We usually see many insects on the street, but if we really want to observe and take pics of them, this is the place where you can do both.
