Every eye in the classroom is fixed on Shinji Kurosawa's lips. " 'Pul gogi,' repeat after me," instructs the Korean language teacher.

"What does it mean?" a student asks. "OK, 'pul' means fire and 'gogi' means meat. So it means Korean barbecue," Kurosawa answers, writing the word on the blackboard. "Masisseoyo?" (Does it taste delicious?) he continues in Korean.

Kurosawa is one of two Korean language teachers at Kanto International Senior High School, which, in a first among Japanese high schools, opened a Korean language department in April.
