Just a short walk from Tokyo Station, with easy access even on rainy days
Seijo Ishii Shin-Marunouchi Building Store is easiest to reach from the Marunouchi Underground Central Exit of Tokyo Station (outside the ticket gates).
From the Marunouchi Underground Central Exit, the store is directly connected via an underground passage, so you can get there without getting wet on rainy days.
If you are coming from above ground, the Shin-Marunouchi Building is across Gyoko-dori from Tokyo Station's Marunouchi Station Square, on the right.
From the Marunouchi North Exit, it is about a 2-minute walk.

Seijo Ishii Shin-Marunouchi Building Store is located on the B1 floor, near the Marunouchi Bote and food court area.
If you are coming from the underground plaza at Tokyo Station, the store is just inside the Shin-Marunouchi Building, making it easy to find and convenient for a quick stop.
With a sales floor of approximately 94 tsubo (about 310 m²), the store is a standard size for Seijo Ishii. Its selection is similar to what you would find at a typical medium-sized store.
Compared with larger stores in the suburbs, such as the Tokyo Dome LaQua store, this location is relatively compact. However, it offers a good selection of food and groceries, including snacks, prepared foods, bento boxes, wine, bread, coffee, imported foods, and seasonings.
For gluten-free options, you can find items such as chiffon cake, cookies, coconut-based snacks, and nuts.
