My three daughters go to doyogako (Saturday Japanese language school) which follows the standard curriculum which is why I knew. I haven't seen them use the kuku though. I'm actually working with the youngest on flashcards right now. I've always thought it very valuable that they do math both there and at their regular US school in the hope that it will mean they aren't dramatically slowed down when math appears in a conversation like second language learners are. They certainly are crazy fluent in both languages otherwise compared to any second language learner, but I recently discovered my oldest tends to think of multiplication products in Japanese first even when in an English context. The brain is tricky :-)
