Kumon for 4 year old?

Hello,

We’re staying in Kyoto, and my 4-year-old, new to Japan, is enrolled in a Japanese kindergarten. She’s doing fine without knowing much Japanese since it’s mainly activity-based, but I’m worried she’s not learning anything academically. I want her to pick up Japanese quickly to make friends in kindergarten, so we tried Kumon trial classes. So far, they’re teaching her numbers in Japanese and having her write them multiple times, plus random hiragana letters without teaching pronunciation.

Her spoken English is already good, and my goal is for her to learn the basics of English, math, writing, and Japanese speaking. She’s very young, but I want her to be at the same level as other students when she starts English-medium elementary school. Is Kumon the right place for her?
If not, any recommendations for programs in Kyoto or online to support her learning?

Thanks for any advice!
