Compare like with like
Begin with the proposed experience: city, confirmed or proposed venue, real ring or mat setting, approximate session length and group size. A real ring is ideally suited to up to twenty participants, while the standard mat format serves groups of ten to thirty. Larger bespoke mat programmes can extend to two hundred, subject to planning. These formats should not be treated as interchangeable merely because each proposal uses the phrase private sumo.
Read the delivery details
Check instructor numbers and backgrounds, interpretation, participation arrangements and any requested observer access. The usual team can include one or two instructors plus an English interpreter, but staffing varies. Particular individuals and former sekitori require advance requests. Then compare equipment and clothing arrangements, changing facilities, transfers, escorting and photography provisions where relevant. Mark unanswered items as questions instead of silently treating them as inclusions. You should be able to explain exactly what each proposal includes.
Check commercial and scheduling terms
Review what the quoted amount covers, how any taxes or additional services are described, and the applicable payment and cancellation conditions. These terms are specific to each booking, so confirm them with the organiser. Ask how amendments to headcount, timing or the programme will be handled. Finally, compare the proposal with the client’s actual priorities and schedule. A useful recommendation explains why the confirmed format fits the brief, with any outstanding request visible before the client makes a decision.
