Should an undergraduate accept a professor's offer to join a Japanese lab as a research student before starting a master's there?

Yes, accepting a kenkyusei offer is usually a smart move because professors rarely accept international students directly into a masters without first testing them in the lab. It also buys you time to prepare for the mandatory entrance exam, learn Japanese, and adjust before high stakes coursework begins.

Accepting a research student or kenkyusei offer before your Japanese masters is usually the right call, because it gives your professor time to see how you work and gives you time to adjust before the pressure of graded coursework starts. Just go in with clear eyes about the costs and the exam risk involved.

Questions To Ask The Professor Before You Say Yes

  • What funding or stipend, if any, is available during the kenkyusei period
  • What proportion of the lab's past research students actually passed the entrance exam
  • Are daily lab meetings conducted in English, Japanese, or a mix of both
  • What happens to your visa and lab position if you fail the exam on the first attempt

My Advice

Send the professor those four questions in writing before you accept, and ask for the answers by email rather than a verbal promise, since you will need that paper trail if funding or exam expectations shift later. If you are self-funding this period, budget for a full year of tuition and living costs so a failed first attempt at the exam does not leave you financially stranded.
