English language school in the heart of the Japanese Alps, and English language learners sharing their experiences online. Teachers post regular items about teaching, learning tools, events in the school, their day to day experiences living & working in a foreign country. Students post on whatever takes their fancy - book reports, festivals in home towns, postcards from business trips etc. A little Brit of England in the guts of Japan!
