Hanawa Town, located in Higashi Shirakawa District, Fukushima Prefecture, is known as a konnyaku production area, and the main venus of the "Toemon Festival" in honor of Toemon, who spreaded the method of making konnyaku throughout the town.

Although the production volume has slowed down compared to its heydays, there are still many mills producing konnyaku in the town, and konnyaku is now a local specialty representating of Hanawa.

As for dishes using konnyaku, "sashimi konnyaku" is one famous example, while "konnyaku no shiraae" is often made at hosueholds. It is made by mixing drained and seasoned tofu and konjac. Tofu is used in dish as if it is a “tofu sauce”.
