This site housed three buildings by the early 1960s, which was replaced with a single, larger building by 2004 (map):

The site is located on the doorstep of Honancho Station 方南町駅, a terminus of the Marunouchi line subway.

This danchi is located near the confluence of the Zenpukujigawa river 善福寺川 and the Kandagawa River 神田川.
