In my village, on the 4th Sunday of the month there is a small community farmer and fish market. This mostly consists of the older folks with small farms or ones who like to make prepared foods. Sometimes there are special events (like free mozuku or free fish soup). I really like attending this and being able to support my neighbors. The first few times, we were often stared at, but now I think most of them expect to see the foreigner couple show up now.
Everything is really cheap, so we always go and buy some produce. It is an easy bike ride away, so we get our exercise at the same time.
