This is a small but cosy museum. It tells a nice history of Shitamachi from the late-1800s to the early-1900s, and how the great earthquake and the war shaped the area and its growth (though it doesn't seem comfortable using the word, "war"). There's a nice recreation of what living in the 1800s look like with a digital screen to depict life at that time. It's on a much smaller scale than some other recreations in Tokyo, but it's nice and cosy nonetheless. It's quite a nice museum to visit, very well curated, and with heart.
