international schools in japan that does not need rec letters or grades

My daughter goes to a prestigious Japanese school and struggled there for about 1 and a half years. She cannot get good grades there despite her being native in both English and Japanese. We are hoping to enroll her in an international school, but have not had any luck yet. She is very good at a lot of extracurricular activities and is usually an academic achiever, but couldn't catch up to the Japanese education since she wasn't raised in a Japanese community. If anyone could help, please do, as we're currently struggling.
