Please check my "Card Shops in Japan" page before planning a trip to this store to verify that it's still where it was when I visited.
Jinbocho is a district in the Chiyoda Ward of Tokyo that is known for its collection of used book stores. It also is home to three baseball card stores - Mint Kanda, Biblio and Wrappers. If you are short on time to go to stores in Tokyo it's not a bad idea to hit these three (or at least Mint Kanda and Wrappers) as they are within a few blocks of each other.
The store I'm going to deal with in this post, Mint Kanda, technically isn't really in Jinbocho - it's about two blocks "outside" of the district and a couple blocks away from Meiji University. It's conveniently located at street level.
I feel like I always end up giving this store kind of short shrift. It's actually a really good store but the two times I've visited in (both this time and in 2013) I had already felt like I had done the bulk of my set building at other shops and I didn't spent a whole lot of time in the store. What I saw this time around was pretty much what I had seen in 2013 - they carry a lot of singles, especially for recent issues, and they are very well organized. I felt they had a decent representation of BBM's issues and I did see older Calbee and Takara cards there are well although at this point I couldn't tell you how old. This was the one store in Tokyo that I saw a lot of Giants team issued cards at although they may have been at other shops and I just didn't notice.
Here's a photo of the inside of the store:
I ended up buying a bunch of Giants team issued cards here as well as a handful of 2019 BBM Time Travel 1979 singles for someone on Twitter. I spent a total of 2450 yen - 950 yen of that was the nine 2019 singles. The one drawback to doing set building here is that their "common" single prices are 100 yen a card, twice as much as they are at Quad Sports and some of the other stores. They do take credit cards.
Here's a map showing their location:
