We, in Tamaishiki, create world-standard teaching materials.
We prepare study materials not only to pass a specific university exam
but to use this as a foundation for their global expansion.
We launched TWELVE to create world-standard study materials.
To this end, TWELVE conducts online events to understand ways
of thinking related to mathematics and research the current state of education worldwide.

All the information obtained from TWELVE is disseminated on our website (HP),
and the Tamaishiki study materials are updated based on this information.
Please lend us your support, wisdom, and ideas to achieve world peace through education.
