You can buy this Sanbon at Bic Camera. You can feel the flavor of the rice and it is easy to drink. It is a Junmai Daiginjo, but the price is also reasonable.
It is a fruity type which is different from the standard thick Tengumai. It has a lot of acidity like grapefruit juice and a good bitterness, but it is not sweet. It is a beautiful sake that shows the ability of the brewer.
