This shop is operated by Kyodaru, a company who operates wide range of sushi shops and restaurants.
This one is one of the most casual, reasonable ones. They used to have workers, but now those workers, cooks are working in the kitchen which is hidden in the back. There are seats around this counter and you order sushi by choosing your orders on the display located in front of your seats.
The prices, seasonal recommendations are all written there. English Chinese and some other languages are available, if my memory is correct.
I was behind my schedule and wanted to have quick lunch. So ordered only two plates each of which has two sushi pieces, that makes total 4 pieces. I think I paid only 301 yen including tax. One of the plate ( bonito sushi ) was discounted yesterday, so I was lucky!
After ordering, it took perhaps 7, 8 minutes, then the bullet train ( shaped carrier ) came and stopped in front of me. How convenient! Take the plates and eat.
Powdered green tea pot is also there, so you put the powder into your cop.
There is a hot water tap, you pour the hot water into the cop. Self-made green tea.
Often expensive, authentic places are scary to order because you don't know how much total it will costs. ( Some authentic places cost $200 or more per person. )
This is easy way to enjoy sushi PLUS it is casual and quick. Are you alone? No problem. After eating, you ask for the check ( also on display ), the staff will come to your seat and make the bill. Go to cashier and pay.
