Can I finish my Master’s degree in Japan without a two-year program or university exchange?

Hey everyone,

I'm currently studying in France and doing an apprenticeship, which unfortunately prevents me from taking part in a university exchange program. If I didn’t have the apprenticeship, I could have done an exchange, but since the apprenticeship covers my tuition fees, I had to prioritize that option.

I’m finishing my Master 1 in Marketing/Tech in july 2025 and would love to complete my Master's degree in Japan. However, from what I’ve researched so far, it seems most universities in Japan require a two-year commitment for a full degree (too long for me, I can only save up money for a year at most). I'm wondering if there are any schools in my field where I could join for just one year and still get a diploma—without needing to go through a university exchange program.

Has anyone been in a similar situation or know of any options for a one-year program in Japan in my field ?

Thanks in advance!
