The weather was very good, so we went to Mount Nasu (or Nasuyama), an inactive volcano. We took the cable car and after arriving at the first stop we walked a little further up, but we did not reach the top because not everyone was in the mood. We strolled through Otawara, a relatively small town and cooler than Tokyo.
Here in Japan, children like to capture living insects, such as beetles, and keep them in a pot with plants. If I had known the importance, yesterday I would have caught a rhinoceros beetle, those who have horns on their heads, when I saw it at Nasu-Shiobara station, I had never seen one alive and flying. Honestly, even dead is already extremely rare to see.
In the evening I decided to go straight to Tokyo airport, since the next morning, very early, I would catch the plane to Beijing. But since it was a local airport, the security guards invited me to leave politely to close the doors, so I had to spend the night in a parking lot across the street from the airport.
