For a “lower shelf” imo jōchū—a bottle costs less than ¥1,000—Kuro Wakashio (黒若潮) is a remarkably good sweet potato shōchū. I’ve tried a number of more expensive brands lately, but I keep coming back to Kuro Wakashio. It has a full body, good nose without being overwhelming. Love it. 

Kampai!

25% Alc./Vol.
Made with Koganesengan sweet potatoes and black kōji.

Produced by Wakashio of Shibushi Machi, Shibushi-shi, Kagoshima prefecture (鹿児島県志布志市志布志町). Try to say that five times fast!

I would have to say the prize for the most ridiculous address in Japan goes to the Shibushi Branch Office of the Shibushi City Hall which is located in Shibushi of Shibushi-chô in Shibushi City, Kagoshima prefecture:

   志布志市志布志町志布志の志布志市役所志布志支所

  (しぶしし・しぶしちょう・しぶしの・しぶし・しやくしょ・しぶし・ししょ)

That is, "Shibushi-shi Shibushi-chô Shibushi no Shibushi Shiyakusho Shibushi Shisho". 

I've heard that a chic and dashing man by the name of Mr. Shigeru Shibu works at that office.
