I've only been there once and sat at a group table. It did appear that private tables were available and my experience at other Japanese Steakhouses has been that private tables are usually available for groups of a certain minimum size, or for a price. I would give them a call and inquire. The food and service were both excellent.
If you have a large enough party you dont have to sit with strangers. Or the sushi bar is available with 2 top tables.
