Obviously only the best come to MLB but Dice-K just turned 30 (although he's had a very injuries lately), Shigetoshi Hasegawa pitched into his late 30's, Kaz Ishii is still pitching in Japan in his late 30's, Kenshin Kawakami is 35, Masa Kobayashi is 36 and still pitching in Japan, Hiroki Kuroda is 35, Hideo Nomo pitched until he was 40 in the majors, Tomo Ohka is 34 and still pitching in Japan, Hideki Okajima is 34, Akinori Otsuka pitched until he was 36, Takashi Saito is 40, Kaz Sasaki pitched until he was 37, Koji Uehara is 35, Masato Yoshii pitched until he was 42. Once again these are only the best of the best that come to America from Japan but just skimming their injury history major arm injuries were rare. Only 2 lost significant time due to elbow injuries and another 2 due to getting hit in the head. I was surprised to find out that Kei Igawa was 31 and I believe the injury that has cost him the last year and a half is an ankle injury.
