Japan–Taiwan relations
The relationship between Japan and Taiwan dates back to 1592 during the Sengoku period of Japan when the Japanese ruler Toyotomi Hideyoshi sent an envoy named Harada Magoshichirou to the Takasago Koku (Japanese: 高砂国, contemporary name referred to Taiwan). The bilateral trading relations continued through the Dutch colonial rule and the Tungning Kingdom of Taiwan in 17th century before the completion of Japan's Sakoku policy.
