To get to Sanseido Bookstore, exit Jimbocho Station on the Toei Shinjuku Line and head towards Ogawamachi and Akihabara on Yasukuni-dori Street.
Sanseido Bookstore is a symbolic store in Jimbocho, so you should spot it easily.
The main entrance of Sanseido Bookstore faces Yasukuni-dori Street, but there is also an entrance/exit on the back side, on Suzuran-dori Street.
And, there is a resting area with shade near the entrance/exit of Sanseido Bookstore where you can sit.
There are circular wooden benches that can accommodate about 10 people.
I confirmed this on weekends and holidays, and although it was crowded, it's suitable for a short break as there are vending machines nearby.
I think it's convenient to know this as a resting point when you get tired from strolling around the Jimbocho Used Bookstore Street.
Also, it's a good place to meet up with someone in Jimbocho.
In addition, there is a "Ogawa Hiroba's table seats" a short walk away, so please stop by if you want to eat lunch in Jimbocho.
Why not use it for a rest while shopping at Sanseido Bookstore or as a resting place near Jimbocho Station?
