The toughest decision a boxer of MMA fighter will face in his career is deciding to hang up the gloves. Boxing history is rife with top notch fighters that hung around too long, and in a sure sign that its matured as a sport MMA is now experiencing the same phenomenon. After his punishing knockout loss to Melvin Manhoef at DREAM 4 it has become apparent that the time has come for Japanese fighting legend Kazushi Sakuraba to retire.

Mixed martial arts is booming in America, but there’s not one specific fighter responsible for its upswing in popularity. That’s not the case in Japan, as Sakuraba is almost universally acknowledged as having brought MMA to the mainstream of Japanese sports and popular culture. In particular, his on-going feud with Brazil’s Gracie family made him a major superstar and national hero.

Sakuraba’s record definitely justifies the high regard in which he’s held, but the reality is that he’s done nothing to build on his legacy for a number of years. His last really impressive win was over former UFC light heavyweight champ Quinton ‘Rampage’ Jackson, but he hasn’t even defeated a credible opponent of any sort since his 2003 win over Kevin Randleman.

Sakuraba is not only 38 years old, but he’s what fight experts consider an ‘old 38′ based on the number of grueling, physically and emotionally draining battles he’s competed in. His 90 minute classic with Royce Gracie alone took a toll that some suggest that Sakuraba has never recovered from. Despite this, he continued to face the best opponents in the world after that fight.

Compounding Sakuraba’s ‘ring age’ was his tendency to face much larger superstars–these ‘dream matches’ would sell tickets in Japan, but are the sort of matchup that would never get sanctioned in the better regulated US fight sport industry. The quality of opponent he faced at heavier weights is mind boggling and includes Wanderlei Silva, Mirko Cro Cop, Vitor Belfort and Antonio Rodrigo Nogueira. Unfortunately, the old saying that ‘a good big man will beat a good little man’ was proven true in these matchups with most ending in losses for Sakuraba by brutal KO or stoppage.

Sakuraba has been less active in the past couple of years, but has shown little indication that he’ll formally retire. Hopefully this decision won’t undermine his legacy or more importantly negatively impact his long term mental and physical health.

Mitsuharu Misawa died in Hiroshima, Japan earlier this year less than a week before his 47th birthday. He was in a tag team match for his Pro Wrestling NOAH promotion with Go Shiozaki against Bison Smith and Akitoshi Saito. Saito hit a back suplex on Misawa, which appeared to knock him unconscious. Medical staff attempted to revive him in the ring, but when CPR failed he was taken to a hospital by ambulance. He never regained consciousness and was pronounced dead on arrival.

There’s at least a small bit of solace in the fact that he died in the ring doing what he loved, and what he did better than just about anyone on the planet. Misawa’s last moments were spent working the kind of brutally stiff, athletically realistic match that got a generation hooked on Japanese wrestling.

A top level amateur wrestler in high school, his skill gained the attention of All Japan Pro Wrestling president Shohei Giant Baba. He made his professional debut in’81, and got his first big break in’84 when he was chosen as the second Tiger Mask replacing Satoru Sayama. In’90, he had his longtime tag team partner (and occasional rival) Toshiaki Kawada unmask him.

Misawa would wrestle as himself from then on, and become an even bigger star in the process. In June,’90 he became one of the top stars in All Japan Pro Wrestling when he defeated Jumbo Tsuruta. That match was his first main event appearance at the venue Cheap Trick made famous in America, the Nippon Budokan. He soon faced Triple Crown Champion Stan Hansen in an unsuccessful challenge for the title, and would become arguably the biggest native star in Japanese pro wrestling for the next decade.

He had legendary battles against Kawada, Hansen, Kenta Kobashi, and Steve Dr. Death Williams in singles competition. Misawa would continue as a mainstay in AJPW until the early part of this decade. After the death of Giant Baba, he left to establish Pro Wrestling NOAH. He would serve as the companys president while wrestling a full time schedule until his untimely death.

Japanese pro wrestling served as an introduction for many American fans into shoot fight sports and MMA. Before the Internet, fans would trade videotapes to stay up on the latest matches from Japan and along with Jushin Thunder Liger and The Great Muta Keiji Mutoh it safe to say that Misawa is one of the wrestlers most responsible for getting a generation of American fans hooked on the product. Were it not for the subculture he created in America, later wrestling promotions like Ring of Honor and MMA promotions like the UFC wouldn’t have had a ready made audience to tap into.
