From Pink Tentacle’s round-up of projected 2008 trends in Japan:

When it comes to nubile young female athlete idols, the letter “B” stands for beach volleyball and badminton. In 2007, beach volleyballer Miwa Asao raised eyebrows when she released a gravure DVD and posed for sexy Sabra magazine, while badminton doubles team Kumiko Ogura and Reiko Shiota (together known as “Ogushio”) were the subject of a popular photobook. In 2008, “B” might also come to signify bowling, as 17-year-old bowling idol (or bowdol, as some like to say) Rina Asada rises to stardom. Last year, Asada began appearing regularly on Nihon TV’s “P-League” late-night bowling program, which features amateurs and professionals competing in tournaments. She also won the women’s national high school bowling championship in July and has been selected as a member of Japan’s national team. Some say her popularity could help spark a bowling craze among the nation’s youth.
