I also remember a trash/treasure market in ueno park and akihabara but cannot remember the days

In Japan, the flea market, there are two meanings antique market and the sense that the market for used goods.
I wrote it is a market of used goods. (I can buy cheap clothes, etc.)
More antique market is often referred to as kottou-ichi(骨董市） in Japan.
If you have written or want to go to either, what do you want to buy, it is easy to introduce.
