Seoul Broadcasting System's 2008 hit drama "On Air" is airing in Japan this month, mainly due to the popularity of hallyu star Park Yong Ha, its star-studded cast and cameo appearances by well-known celebrities.

Park is one of the rare multi-talented successful hallyu stars who has a career in both acting and singing. When he and "On Air" co-star Song Yoon Ah held a press meeting in Japan, hundreds of other guests and thousands of fans outside waited to catch a glimpse of Park.

Park has visited Hawai'i several times while between projects, but now he spends a great deal of time in Japan and South Korea.

In Japan, much of his time is spent working on his singing career. He has held several concerts in several major cities there, each time playing to sold-out crowds.

Park has won Japan's 2008 Golden Disc Award for Best Asian Artist, but he's most well-known for his role in the biggest Korean drama hit "Winter Sonata," also known as "Winter Ballad." Park played Sang-hyuk, who was to marry Choi Ji Woo but loses her to Bae Yong Joon.

Park also was the vocalist for the theme song to another hit Korean drama series, "All In," starring Lee Byung Hu, as well as for the theme to "On Air."

Park's "On Air" co-star Song Yoon Ah is also famous for co-starring with Bae in the hit series "Hotelier" and has a large fan base in Japan as well.

Song's big debut was in a KBS series "Paper Crane" co-starring Ryu Shi Won in the early years of hallyu, the Korean cultural wave.

"On Air" had a unique storyline that gave insight into the entertainment industry in Korea, allowing fans a glimpse behind the scenes.

I think the show gave people a better perception of production and emotions involved between writers, directors and celebrity managers, but didn't touch on the tight budget constraints the directors are usually faced with.
