Embassy of Republic of Korea in Japan: {Written in Korean, translated by me}

General Sightseeing (C-3-9)

Visa details:

Trips less than 90 days, visa valid for 3 months

Required form:

Application form, passport, photo, fee, proof of financial support during your stay in Korea or ID (Residence card)

• If you are student from Southeastern Asia region, you need a proof of enrollment from your school AND proof of financial support (if you don't have any, you need it from your parents in your home country)

• Depending on your educational institution, more or less paperworks can be required according to the assessment of MEXT or equivalent organization.

Since you said you're from Vietnam —which is likely to be in 'southeastern asia' category, you'll need a 'proof of enrollment' and 'proof of financial support'. I think you should contact the embassy (+81-3-3452-7611/9 , Mon-Fri 09:00-18:00, lunch time 12:00-13:30) for exact requirement.
