Soroban school
Recently, my son went to soroban school near our house (2min. By walk from our house ) This school is held in private house so it dose not seem like "school". Soroban is very good custom in Japan, I think, because they use fingures very rapidly so it stimulate brain. Soroban specialist can calculate adding, multiplication without soroban. It is amazing ! He likes soroban school because he can play outside with their friends after finising soroban school !
