A literary map of Childhood Years (幼少時代, 1957) by Tanizaki Jun'ichiro — Japan's preeminent modernist novelist, writing in his seventies about a Meiji childhood in the merchant heart of old Edo.

Each pin marks a real place in the Nihombashi shitamachi district: family homes, the local temple and shrine, restaurants, theaters, and the streets young Jun'ichiro walked daily. This was a world swept away by the 1923 earthquake and the 1945 firebombing.

Blue pins survive in some form today. Amber pins are gone — lost to earthquake, fire, or urban transformation.
