Thanks and praise to Sheila Campbell for passing on this important news!
If you are not already aware of it, Jupiter is a huge emporium of imported goods in the underground Porta shopping complex that lies in front of Kyoto Station. They have an impressive selection of confectionery and coffee, plus cereals, imported booze and ingredients for Mexican, Italian & Asian cuisine. Most importantly they have Hobnobs, the finest biscuits known to man.
Coming out of Kyoto station’s central exit, take the first flight of stairs down and walk east and then north. Jupiter is on the left corner opposite Lotteria. You can find a simple map here and clever little 3-D map thingy here. Jupiter is number 107 on the map.
Open everyday from 9:00 ~ 21:00
