Another sake I bought at Chiba station.
It also says "secret sake," but I'm guessing that means "aged.
Found it at Roppongi Midtown and drank it at home.
I bought it on impulse when I was told that it was "just bottled and brought to Tokyo" and it was indeed delicious!
During a trip to Tokyo the other month, a monk friend of mine asked me to buy a bottle of Sasaki Shuzo sake, and since I was on vacation, I bought it at Isetan in Kyoto Station on my way home.
One bottle was a gift to the monk.
I heard it is the family home of actor Kuranosuke Sasaki.
