Anyone have experience with JET Academy (Japanese language school)?

Does anyone know anything about this school? The name is so similar to the JET Programme that it’s really hard to find info about it. Despite being in Tokyo and established in 1988 (according to [Nisshinkyo](https://www.nisshinkyo.org/search/college.php?id=207&lng=2)), I can barely find any reviews or mentions of them aside from a few Google reviews, Study abroad agents and their Facebook page.
