ceramic bottle is a Japanese shochu bottle from Unkai Shuzo, a brewery in Miyazaki Prefecture. The text on the bottle reads "宮崎名産" (Miyazaki meisan), which translates to "Miyazaki local product," and "雲海酒造" (Unkai Shuzo), which is the name of the company.

Unkai Shuzo is well-known for its shochu, especially its soba (buckwheat) shochu called "Unkai". Shochu is a Japanese distilled liquor, while sake is a fermented liquor, similar to beer or wine. The brewery has been in operation since 1967 and has several distilleries in Miyazaki and Kagoshima prefectures.

The bottle itself is a type of tokkuri, a traditional vessel used for serving sake or shochu. This particular bottle has a speckled design and a black glaze on the top.
