You can taste Zuiyo, ZUIYO CO.,LTD. from Kumamoto prefecture, and Benten, Goto Shuzoten from Yamagata prefecture.
Zuiyo (ZUIYO CO.,LTD.)
Zuiyo is founded in 1867, in Kumamoto. Kumamoto is a city on the Japanese island of Kyushu. The brewery is in Kawashiri, the south of Kumamoto city.
Sake can be enjoyed at a various range of temperatures. Each temperature has a different name, and you can enjoy unique aspects of the same sake when you try it at different temperatures.
Houjun Junmai Zuiyo 
55℃ is called Atsu-kan which is vapor rises from the tokkuri (larger sake jars). The tokkuri and choko (small sake cups) are hot to the touch. The sake’s aromas are sharpened and it tastes dry, with a clean finish.
Generally speaking, Atsu-kan is suited to hot pot (“nabe”) dishes and foods made with a lot of oil and fat. The fat from the food coats your tongue and palate, which desensitizes your taste buds. As a result, your second bite is less tasty than first. Your food would taste better if you washed your mouth between mouthfuls. Sipping Atsu-kan is an easy way to wash away the fat deposits.
How is sake heated?
To warm up sake, place the tokkuri containing sake in a pot of hot water. The tokkuri gradually heats up and the heat is transmitted to the sake. It is heated to a temperature before alcohol begins to evaporate, so that the aromas do not dissipate.
What’s Tokkuri?
The server of a sake set is a flask called a tokkuri (徳利). A tokkuri is generally bulbous with a narrow neck, but may have a variety of other shapes, including that of a spouted serving bowl (katakuchi).

Benten (Goto Shuzoten)
Based in Okitama, Yamagata Prefecture, Goto Shuzoten is a jizake brewery dedicated to the small-lot production of high-quality sake since 1788. The current president is the eighth-generation owner, and his successor works at the brewery among the kurabito (brewery workers) during the winter sake-making months.
Primarily using rice grown by contracted producers, among them the brewery’ s own kurabito, Goto Shuzoten brews junmai-shu and junmai ginjo-shu, among others.
Its preferred rice varieties are sake rice such as Dewasansan, Tsuyahime, Kamenoo and Yamada Nishiki, especially those produced locally in Yamagata. Small-lot production and Yamagata’ s natural blessings ensure the excellent quality and great taste of Goto Shuzoten’ s sake.
Benten （辯天）

Benzaiten has traditionally been worshipped by musicians, dancers and other artists.
