First of all, I would like to draw your attention to that:

2) therefore, most of our students are Japanese, and courses are taught in Japanese and partially English-Japanese bilingual environment except the IB course, and

Although Tamagawa Academy is not a mission school, the School regards religion as important for education, but its educational philosophy is "education is not for a religion but a religion is for education".
Being based on such philosophy, the School introduces the teaching of Christianity for "Zenjin" (well-rounded person) Education of Tamagawa.

As mentioned ealier, Tamagawa is not a mission school. So, students with non-religion/a different religion are not forced to follow the teaching of the Christianity.
