Joining
Whether you have competed before or have simply never been given a problem that took more than a minute, you are welcome. We start from reasoning, not from a syllabus.
One hour a week, taken seriously. We ask members to arrive prepared and attend regularly.
How to apply
Google sign-in confirms you are a Tokyo International School student and stops duplicate or impersonated applications. It does not make you a member.
Your name, grade, what interests you, why you would like to join, and whether Friday afternoons work. About five minutes.
We read every application and reply to your school email address.
