We will never say, "No."
Since hundreds years ago, tourists from all over Japan visited Kannawa to have medical therapy using hot spring. In many "tojiyado", inns providing hot spring therapy, Jigokumushi cooking was introduced and became popular to entertain staying guests. This way of cooking is said to start in early Edo period, mid 17 century.
In March, 2010, the city of Beppu opened Jigokumushi Kobo Kannawa (Kobo) as one of the city's re-development programs to preserve this old diet culture, and entrusted Kannawa Kyoei-kai, the merchant association of Kannawa area, with the management of this facility.
