We don't necessarily visit playschools, nurseries or kindergartens and definitely don't look at them as thoroughly as the primary and secondary schools (and only publish full GSGI write-ups on them if they are part of a primary or K-12 school), but these are amongst the ones in Tokyo recommended or mentioned by parents. We list them here just to give you a place to start, to help you make up your own short list.
We always appreciate any feedback from parents (contact us), and we'll remove schools or add them as we hear about them or receive updates, even from this informal list.
