Hi there. The answers here are correct. For the one act performances, you need to arrive at the box office about 60 before the performance and wait in a line. I don't think you are able to purchase the one act performances ahead of time. I actually decided to purchase 2 acts and stayed for both. ALL parties need to be present at the time of purchase. You cannot hold seats for anyone else. Hope that helps.

It is usually a three-part 4-4.5 hour long performance.

It actually depends on being a weekday or weekends....but if you are coming from far better to have a firm booking

Not that I know of ... When I went I wore jeans and nice summer T shirt more business like in style not casual. But people were dressed many different ways some in summer Kimono as well... but nothing really fancy... Hope that helps

Typically you can buy tickets for kabuki about a month before online but that's for the entire performance only in the evening.
