Japanese Language Schools in Tokyo, Japan

Transportation is more expensive than Korea, so if you go to a language school, I would recommend that you consider which area is cheaper.

If you already have an N5 Japanese level or you can read Hiragana and Katakana, I totally recommend JCLI, everything during the class is in Japanese and it makes it more interesting to learn. Also most of the classmates don't speak English, so It becomes an excellent opportunity to really practice and learn Japanese every single day.
Enjoy the reception and assistant office workers who are excellent at helping - even in English and Spanish (which really worked well for me.) All the teachers and classmates are really friendly and even if you cannot talk fluently with everybody, they will still help you a lot; same goes for every place in Japan.

The teachers were very motivated and friendly. I made a lot of progress in learning the language.
The location of the school right in shinjuku is great, it is pretty amazing that it is in one of the busiest districts of Tokyo but it is very calm in the school area because it is located right next to a shrine.

Kindness of the staff, very high level teaching, much time dedicated to conversation.
Large number of Europeans makes it possible to abuse the English language inside the school

Good atmosphere
I would say very dissatisfied with the quality of the courses. It was a beginner courses with no real beginners. All had some notions and the courses were mainly based on writing. I paid 3 weeks of classes for nothing since those who were present had either started learning in their country or "redoubled ". Completely ineffective. Great disappointment. I did not expect so much contempt for the student.

Teachers and organization. The manager at Tokyo school, Demi, answered all my questions the day after the questions were sent. Everything is available, clear and fast. The teachers are all different, with their own approach to teaching.
Many thanks to the school! Maybe I will come again for a couple of weeks. I did not assess the events, because I could not attend any. But it's my fault. The school organized an activity every Friday, for a small fee. Classes are OK. There is air conditioning. The building overlooks an office building and a temple, quite quiet.
