Ishimura Manseido Honten is a Japanese dessert shop in Fukuoka that opened in 1905. It sells a marshmallow dessert called Tsurunokonoko, which is served with ice cream hidden underneath the marshmallow. Tsurunokonoko takes about five minutes to prepare after ordering, and the cafe closes at 6 p.m. The marshmallow alone is plain, so it needs to be mixed with the ice cream.
