Looking for honest reviews: ISI, KAI, TCJ language schools โ€“ which is best for career/MBA in Japan?

Hi everyone! ๐Ÿ‘‹

Iโ€™m planning to move to Japan in April 2026 to join a Japanese language school.
My goal is to study until around JLPT N2 level, then either work in marketing or do an MBA in Japan.

Iโ€™ve done quite a bit of research already and shortlisted some schools:

  • ISI Japanese Language School (Career Japanese Course, Takadanobaba campus)
  • KAI Japanese Language School
  • Tokyo Central Japanese Language School (TCJ)
  • (also considering Yokohama International Academy & Naganuma School as backups)

But Iโ€™d love to hear from people who have actually studied at these schools (or know someone who did):

  • How was the teaching style, homework load, and pace?
  • Was the career support / job guidance actually useful?
  • Did they help with part-time job hunting or internship connections?
  • Any pros/cons you noticed (too strict, too relaxed, crowded classes, expensive, etc.)?
  • Would you recommend your school to someone planning to work or do MBA in Japan?

A bit about me:

  • Indian, currently studying Japanese at N5 level (planning to take JLPT N5 in Dec 2025)
  • Bachelorโ€™s in computer science + 1 year AWS work experience + freelance marketing now
  • Age: early 20s; realistic goal: study ~1.5โ€“2 years โ†’ work or MBA

I know thereโ€™s no perfect school, but Iโ€™d really love real, honest feedback โ€” good and bad โ€” to help decide which one fits best for someone who wants to build a career in Japan, not just language for travel.

Thanks so much in advance! ๐Ÿ™โœจ
