On Thursday, May 22, 2025, at the request of Dovletmammet Azadi Turkmen National Institute of World Language, a special online seminar titled “Comparison of Turkmen and Japanese Languages and Its Application to Japanese Language Education – Focusing on Grammatical Forms Expressing Necessity” was held by Specially Appointed Associate Professor Hidaka Shinsuke, who has experience in teaching Japanese at the International University for the Humanities and Development. A total of 20 people participated, including 5 faculty members and 15 students from Dovletmammet Azadi Turkmen National Institute of World Language.

In this seminar, he contrasted two grammatical forms expressing necessity in Turkmen—V-mAlI and V-mAk(lIk) gerek—with the Japanese expressions “nakute wa ikenai,” “hitsuyō ga aru,” “ni chigai nai,” and “hazuda.” In particular, the research results showed that while V-mAlI allows past tense connection and can express probability, V-mAk(lIk) gerek cannot connect to the past tense and cannot express probability.

Through this contrastive analysis, he clarified that as a teaching guideline in Japanese language education, both V-mAlI and V-mAk(lIk) gerek forms can correspond to expressions of necessity, but only V-mAlI corresponds to expressions of probability (such as “~nichigainai” and “~hazuda”).

This achievement greatly contributes to the refinement of Japanese language teaching materials for native Turkmen speakers and provides insights that contribute to the accuracy of grammatical explanations.
