We've all heard the "You know you've been in Japan too long when . . ." jokes followed by a list of tired expressions, such as "when you start bowing while you're on the phone." Ha-ha-ha. It was probably funny the first 100 times you heard it but can't someone come up with something new?!
Yes.
Here's an updated list. This is not a list of ways to know you've been in Japan too long, but ways to know when you've been here waaaaaay too long. Some foreigners will feel that even a year is way too long, but others, such as "lifers," may feel way too long is a little longer. Or a lot longer. You decide.
