Can I still apply for a September/October 2026 intake at a language school in Osaka or Kyoto right now for a student visa?

Hey everyone, I want to study at a language school in Osaka or Kyoto starting this September or October. I am looking at doing either a 6-month or a 1-year course, and I absolutely need a **Student Visa** because I want to work part-time. I was told by my counsellor there is still time to apply right now and get in for the upcoming September/October term, and my financial documents/funds will be fully ready next week. Is it still possible to apply and get a student visa for September/October 2026 at this stage in late June, or are the immigration deadlines for student visas completely closed? Thanks!
