Most Japanese kids end up going to cram schools to make up for what the school system (both public and private) lacks. The system sucks---long hours, Saturday classes are being reintroduced this spring, and the cram schools are usually at least 2 hours long---sometimes as much as 4 or 5 hours. And Japan still can't get into the top 10 of the Education Index.
