A materials exhibition corner inside the ticket gates of Ichigaya Station on the Tokyo Metro Namboku Line. From 1989 to 1995, in conjunction with the construction of the Tokyo Metro Namboku Line, archaeological surveys were carried out at 14 sites between Tameike and Komagome on Subway Line No. 7. On display are photos of the excavation work at the time, the “Castle Construction Folding Screen” depicting the construction of Sunpu Castle (Shizuoka City), which Tokugawa Ieyasu ordered the feudal lords to build, and, on the floor, an enlarged “Edo Kiriezu” map of the area around present-day Kioicho. In addition, the real stone wall, reassembled from part of a stone wall excavated at Kijibashi Bridge in Kudan-minami, is worth seeing.

Tokyo Metro has lots of places where stone walls of Edo Castle are restored and displayed, but since the tracks run near the outer and inner moats, they tend to turn up when digging, and since they're historical remains, I guess that's why they're preserved. This one is the stone wall remains inside the station past the ticket gates. Remains related to the outer moat around Yotsuya and Ichigaya.

A small corner where you can learn about the history of Edo. You can learn history through the magnificent stone wall, the depiction on the wall of how the stones were transported, a reconstructed map of Edo, and more. It's surprising that this is inside Tokyo Metro!

It's a facility set up in the underground connecting passage of Ichigaya Station, something you might call a place to relax and take a breather. It's unstaffed, and the kind of place you'd walk past in under 10 steps. There are about 3 chairs, and it's about 20 tatami mats in size. I have absolutely no interest in history, but for history buffs and people who go on walks with an old map in hand, isn't this a mouth-watering place? It seems they display photos of the scenery before the ground under Ichigaya Station was dug, and even folding-screen paintings from the much older Sengoku (Warring States) period. Part of the wall is a stone wall, letting you recall the castle ruins of that era. That is, if it's the real thing... Since I use it as a connecting route to the Namboku Line and have never once stopped to look or read, everything I've said is purely from my imagination, so for those who are interested, I strongly recommend checking it out with your own eyes. Apart from that, what I recommend is that the entire underground area is by far the cleanest. The walls in almost all areas, including the passages and toilets, are waxed, giving it a bright look. There's little dust buildup, and its beauty is a world apart from Nagatacho Station's dust-covered walls and its ceiling dangling with numerous tubes for groundwater treatment, which remind you of life-prolonging medical treatment. I think it's the cleanest even within all of Tokyo Metro. As expected of the station right at the foot of Yasukuni Shrine.

It's on the way when transferring from the Toei Shinjuku Line to the Tokyo Metro Namboku Line. The first thing that catches your eye is the stone wall. At your feet is an old map of Edo. You can see what this area used to look like. It's a good place to take a short break.
