NHK has the good fortune to control the Japan rights to several Korean TV dramas that are very popular, and they don't let them go to waste. They use clips as resources on other shows, especially their Korean language classes.
This week, they even use them on a special prime time edition of the English-learning variety show "Eigo de Shabera Night" (NHK-G, Monday, 9:15 p.m.), which travels across the Japan Sea. The show's regular gung-ho announcer, Matsumoto-san, takes a tour of locations used in the hit series "Winter Sonata" (in summer, no less), which are already hugely popular with tourists from all over Asia.
He also tests Koreans' English ability, which, according to TOEIC records, is much better than the average Japanese. Matsumoto also interviews actor Lee Byung Hun, who stars in "All In," a TV drama currently being broadcast on NHK.
