Looking for a language school in Tokyo/Saitama area, 3 week program, day classes

Hi! I was wondering if anyone knows of any language schools that run 3 week programs (August) . Looking for like morning to/and afternoon classes from Monday-Friday. (While I was searching I noticed a lot of places seem to only have like 3 hour classes in the morning or afternoon which is a bit short?) I'm around intermediate level, and also 17 so I'm looking for schools that accept minors!

the only two places that aligned with my schedule were JaLS and Akamonkai but they both only do morning classes and I was hoping for a bit more

I'm going to be living and commuting from Saitama Midori ward. I don't need the commute to be super close, but anything more than 1h30 is too much, closer would of course be preferable. I don't really mind if ppl just give me locations in tokyo though !

This might be a bit of a detailed request but I figured I might ask anyways and see if anyone knows anything! Thank you
