Referral Letter / Shokaijo
紹介状 (shōkaijō)
A referral letter (紹介状, shōkaijō) is a formal document issued by your primary care doctor or local clinic introducing you to a specialist or larger hospital. It contains your medical history, current diagnosis, test results, and the reason for the referral. Presenting a referral letter at a large hospital waives the selected hospital fee and allows smooth information transfer between your doctors.
Obtaining a referral letter from a neighborhood clinic (クリニック) before visiting a large hospital can save you several thousand yen in additional fees and speeds up your appointment.
