Years ago it was worthwhile to buy new cameras in Japan (It was generally cheaper). I don’t think that’s true anymore, for most new cameras the price difference (Japan – other countries) is almost nonexistent.
But when people travelling to Japan ask me, I tell them that if they are really into photography what is still worthwhile is to enjoy visiting secondhand camera shops. Many of them have disappeared but there are still plenty of secondhand and oldschool film camera shops that you can find in the most random places. This one in the pictures is a very local shop that Carlos and me found while walking around Asakusa. From outside it doesn’t feel like a camera shop, it blends with the soba restaurants and coffee places in the same street.
