Has anyone ever spent a whole year in Japan as a Kōkō 3 (senior high school 3rd year) student, from April to March, and with which organization?

Hello everyone,

I’m looking to find out if anyone here has done a full school year exchange in Japan as a senior (高校3年生), staying from the start of the Japanese school year (April) until the end (March).

Did you have this experience?
Were you able to attend classes for the entire year and fully participate in school life (clubs, festivals, exams, graduation ceremony)?

I’d also love to hear any advice you might have for preparing well for this exchange year, especially for a student coming from abroad.

Thanks in advance for your feedback!
