Treasures Found Here
Japan’s Oldest Surviving Piano, Gifted by Siebold
This piano was given by German physician Philipp Franz von Siebold to the Kumaya family when Siebold returned to Europe at the end of the Edo period. It is believed to be the earliest piano brought to Japan that still survives today.
The Main Building of Kumaya Family Residence
Built in 1768 during the middle of the Edo period, this large townhouse is a representative example of the residences of wealthy regional merchants. It was designated a National Important Cultural Property in 1974. The residence is part of a historical collection dating back to the Edo period, centered around four nationally designated Important Cultural Properties.
Goemon Coffee
Goemon Coffee is a recreation of the coffee Yoshikazu, the fourth-generation family head who received Siebold’s piano, is said to have enjoyed. Yoshikazu commissioned a disciple of Siebold to obtain the coffee, which was considered a rare treat at the time. The Goemon Coffee served at Kumaya today was recreated by deciphering historical documents, and we would be delighted if you gave it a try during the concert.
