Many Japanese people sleep while sitting on the train; some sleep while standing up. This may be hard to believe. One of my English teachers from the U.S. said he couldn't imagine it before he came to Japan, but then he saw people doing it every morning in Tokyo.
I’ve never seen people sleeping on the train outside Japan. I wonder what you think when you see people sleeping on the train. I’ve read that some foreign men have named it the “Japanese siesta”.
When I get on the underground train in New York, I tried to sleep out of habit, but then I remembered I wasn’t in Japan and woke up quickly.
Do you sleep on the train in your country?
Koir, thaks for correcting my English.
