YOKOHAMA (Kyodo) An international school affiliated with the Indian government opened Friday in Yokohama with 13 kindergarten and three elementary school children starting a new year.

The school, run by India International School in Japan, uses a closed municipal elementary school leased by the city.

Classes are conducted in English and promote Indian-style education, particularly math, on which India is known to focus, such as by teaching mental arithmetic calculation involving double-digit figures.

IISJ is a nonprofit organization affiliated with the Indian government's Central Board of Secondary Education. About 350 students — from kindergarten to high school students — attend the international school it operates in Koto Ward, Tokyo.
