Ryogoku Kokugikan

Advance tickets go on sale about a month before each tournament. They’re not difficult to get hold of (apart from the most expensive box seats) - though weekends generally sell out. Some unreserved, back-row balcony seats (one per person) are always held back for sale from 8am on the day of the tournament. Many spectators watch bouts between younger fighters from downstairs box seats until the ticket holders arrive in the mid afternoon. There’s also a small museum (closed on tournament days).
