Purchased from Kodama, a local sake shop. I like to drink it while reading the description on Kodama's website. It has a delicate, dry sweetness that spreads slightly!

Very rich. It goes well with food and dishes on its own, but I think it would go really well with chocolate. If you want, Tatsusen tastes like chocolate.
