Menu only in Japanese. No phone, no CC, no nothing

Fukuchan is a special kind of sashimiya. It serves enormous amounts of good sashimi at a very decent price, but the rules of the game are:
1) No booking
2) 90 minutes to eat, then you must go.
3) All orders other than rice and beer must be made at the beginning.
4) The place is almost always mobbed. Patience is accordingly a must.
5) This is not a place where you go alone. Since the servings are truly huge, go with a very minimum of three friends, or you will not be able to eat more than two or three things.
The owner is used to seeing white faces, but the menu is exclusively in Japanese.
Since booking is impossible anyway, I will only give you directions on how to get there.
Get out in Shibuya, Hachiko exit, go straight towards the Inokashira Line Station and cross the street, turn immediately left, then right following the Inokashira Line, go straight and after maybe two hundred meters turn left on the third street. You will see Fukuchan right there (the sign is in Japanese).
