It is said that the process of manufacture of Yamaguchi Uiro was invented by Jirosaku AKITSU in Yamaguchi City, Suo Province in the Muromachi period. After that, he was given the trade name of Fukudaya by the lord of Choshu domain and started a business along the present Hagi Okan (Hagi Highway) at Ouchimihori in Yamaguchi City. This Uiro was favored by Chuya NAKAHARA, but closed down due to the death of their successor in the Pacific War.
