Japanese citizens in possession of a valid Japanese passport do not need a visa for airport transit, tourist or business trips (for stays up to 90 days) to Germany. However, the validity of their passport has to last until at least three months after the intended date of departure from Germany. The passport must have been issued within the previous 10 years.
