I think this is a place where people who want to buy electronic devices visit, but there may be more specialized parts than I think. .. You may also find a two-hole outlet or cable here.
In Japan, it is similar to the back street of Akihabara.
(If the front is a mass retailer, the back is somehow a specialty store)

We recommend that you walk with your bag in front of you when visiting.
