About Mr. Oka's House
Oka-san's House TOMO is a community hub located in Kamikitazawa, Setagaya Ward, housed in a Showa-era detached home.
This used to be the “community classroom” where the owner’s great-aunt, Chitose Oka, taught English and piano.
Prompted by the wish expressed in his will—“I hope this house will be put to good use for the children and the community”—
Community activities began with our friends, and in 2010, we relaunched as “Oka-san no Ie TOMO.”
Today, it is beloved as a “community living room” where everyone is welcome, attracting more than 2,000 visitors annually.
We will create a place where diverse personalities come together, pool their wisdom, and find warmth and a moment of respite.
We would be grateful for your support in any way you can—whether by attending our events, participating in our activities, or using our facilities.

Old Items at Mr. Oka's House TOMO
The many vintage items at Mr. Oka’s House TOMO. Here, owner Koike shares the stories he knows about them.
■ Part 1: Foot-Powered Organ
When the lid is opened, it reads “YAMAHA HAMAMATSU.” During repairs in 2005, the organ was found to be 103 years old. Since Mr. Oka passed away in 2006 at age 99, it had been with him nearly his entire life. Played by children and used for hymns at living room concerts, its simple tone still feels fresh today.

■ Part 2 Foot-powered sewing machine
This is a treadle sewing machine from Mr. Oka’s house, where two women once lived. From a time before fast fashion, it was used to make everyday items by hand. With its Art Deco style, it likely dates to the 1940s. Even after 80 years, it still works perfectly with only a new belt — a reminder of the beauty of analog technology.
