Under the philosophy that "each student is unique, and true education is one that accurately responds to those individual differences," we have provided authentic, individualized instruction tailored to the needs of each student. Based on original curricula designed to match each student's learning pace, TOMAS Co., Ltd. offers one-on-one instruction, where a dedicated subject-specific instructor teaches a single student. This approach is applied to support the academic and admissions goals of elementary, junior high, and high school students. Together with our seven group companies-TOMAS Co., Ltd. Meimonkai Co., Ltd., Shingakai Co., Ltd., School TOMAS Co., Ltd., Plus One Kyoiku Co., Ltd., Sundai TOMAS Co., Ltd., and Cocokara T-Chers Co., Ltd.-we maximize the scale and synergy of the Riso Kyoiku Group to build a "Comprehensive Human Life Information."
