The sake is the photo is: 窶ケテ?窶氾仰 窶怒ツ湘ク窶伉「 ツ辛ナ津サツ(窶ーテ?ツ静ッツ)
Name: Kinryo
Grade: Honjouzou / Karakuchi
Price: 1,692 yen (1800ml bottle)
FYI, the price for its very top grade is 10,000 yen plus for the same-size bottle.
The company accepts direct orders at this website but appears not to ship overseas. It offers no information on overseas shipping. Still, I found an email address:
kinryo-sato@crux.ocn.ne.jp
(I'm not sure whether this email address is for the brewer itself. It might be a sake restaurant that it is operating. Also, there is no guarantee that they understand English.)
If you really want it, I think the best bet is to have someone living in Japan to place the order, accept the delivery and then ship the bottles to you in the UK.
Hope it helps!
