A comparison between normal vision from 1.5m away compared to Akiyama's vision

Akiyama Kazuhiko (秋山 和彦) is a SASUKE All-Star who became the first man to achieve Kanzenseiha, doing so in SASUKE 4. He has not been able to repeat his success however, due in part to an eye condition known as degenerative retinosis that has plagued him for years. His eye condition also forced him to retire from crab trapping, and he is now a sports massage therapist. He has also been a soldier in Japan's Self Defence Force, and a Greco-Roman Wrestler. His victory in SASUKE 4 was his only trip to the Final Stage. Of the 20 tournaments he has entered, he has cleared the First Stage 6 times, the Second Stage three times, the Third and Final Stages once.

Early Competitions

Akiyama was given #100 in SASUKE 2, due to setting a record in Kinniku Banzuke's Quick Muscle event, however he was unable to clear the Second Stage because he took too much time on the Spider Walk and he hesitated on the Goren Hammer, and as a result he timed out on the Wall Lifting. He made the same mistakes in SASUKE 3 and timed out at the exact same spot.

Not being seen as a serious threat to achieve kanzenseiha, he was given #86 in the fourth tournament. He was able to clear the Goren Hammer fairly quickly and finished off a second stage clear with a backflip. In the redesigned Third Stage, Akiyama fell just short of the platform at the end of the Pipe Slider, but was able to hold himself out of the water and climb up to the top. He was the only person to reach the Final Stage, where he cleared the 15 meter rope climb in just 24 seconds, becoming the first person in SASUKE history to achieve kanzenseiha.

After Kanzenseiha

Akiyama took SASUKE 5 off and returned in the fall of 2000 on SASUKE 6. However, he mis-hit the trampoline of the Jump Hang and failed. He went out on the same obstacle in the next two competitions, though he touched the net both times, he was unable to grip on and fell into the water. SASUKE 9 saw one of the most shocking defeats ever in the history of the show. He was taken out on the very first obstacle, the Godantobi, after his foot touched the water after clearing the obstacle. In the 10th anniversary competition he redeemed himself on the past failures only to be stopped by the Soritatsu Kabe. In SASUKE 11 he finally passed the First Stage with a mere 00.03 seconds left. He made all the way to Stage Three, before failing the Body Prop. In the next tournament he continued his good form by making to the Third Stage once more. There he made it to the Pipe Slider, but fell short of the platform and missed the chanche of trying to get a second kanzenseiha. In SASUKE 13 he was expected to do well once again but he surprisingly fell on the new Nejireta Kabe (probably the darkness penalized Akiyama). In SASUKE 14, now competing in the daytime, he passed the obstacle but failed the Soritatsu Kabe, and then he met the same fate in the next competition. In SASUKE 16 he was able to clear the First Stage only to be one of the many victims of the deadly Metal Spin. SASUKE 17 proved to be a disappointment, as he fell on the new Circle Slider.

After Nagano Makoto's kanzenseiha, he vowed to retire, skipping the next two competitions, before making a return in the 20th anniversary tournament, in which he was the first competitor to run that day as he wore number #1901 (equivalent to #1). Here he struggled on the Pole Maze and he lost his grip on the rope of the Half Pipe Attack, when time was about to expire. He returned in SASUKE 22 but failed on the same obstacle, this time slipping on the half-pipe immediately after starting the run. He again returned in SASUKE 24, in which he took his revenge on the Half Pipe Attack, only to be defeated one more time by the Soritatsu Kabe, and this was the same result of the next competition. He made his final appearance in SASUKE 28, failing the Spin Bridge.

He was invited to compete in the 30th anniversary tournament, but he declined the offer. He was present in SASUKE 32 on the occasion of Nagano Makoto's last run, and he also took part on a side event in which competitors faced four First Stage obstacles for real, and another four on a Super Mario Bros. game. He attempted it with 7 other competitors, including Yamada Katsumi failed at the transistion from the Quad Steps to the Rolling Hill.
