The first wave of Japanese riders to contest GPs was in the 1960s, riders such as Takahashi, Suzuki, Morishita and Itoh, raced full seasons. Quite a few other riders came over regularly throughout the season, especially for the TT,  After 1967 they disappeared, which I presume was due to the Japanese factories withdrawing from GP racing.

Hideo Kanaya (1972 - 1975) and then Ikujiro Takai (1975) came back over in the 1970s with Yamaha as factory riders, but they only contested the first few GPs of the season before returning to Japan. Kanaya was a contender, rarely out of podium positions and winning GPs and Takai raced the first few GPs of the 1975 season and finished 2nd in the one he finished. The Japanese Kawasaki works riders Wada and Kiyohara also did the same in 1977 when the KR250s were being introduced. They did a few GPs, placing well, then headed back to Japan and were never seen again.

Does anyone know why they didn't, or weren't allowed to, race the full season and go for the championship? They were obviously good enough. I can understand that they were factory test riders, but the riders in the 60s did full seasons and went for the title and presumably were also factory riders/testers.

Note: I am excluding Takazumi Katayama for the discussion as, I think he came across as a privateer first and not as a factory rider, so appears to be different from the others.

When Takazumi Katayama first came to Europe for the second half of the 1974 season (starting in Assen) he had, I believe, factory support. But when he came back for good at the start of the 1976 season,he indeed was a privateer. Raced Sarome-sponsored 250 and 350 TZ's in 1976 and 1977, then was entrusted with a factory 500 Yamaha for the 1978 season, and then signed for Honda in 1979 to develop the 4-stroke 500 NR ( and race a private 500 RG Suzuki to keep himself busy when the "Never Ready" was, well, not ready ....) and later successfully race the 500 NS.

 

As to the reason why the japanese test riders never stayed for the whole season ...... well, that's a good question   It was said at the times that their trip to Europe was some sort of "reward" by their employer ..... Suzuki also sent over some of their test riders for short stints, Hiroyuki Kawasaki was perhaps the most competitive.  I think that, outside of Katayama, the first factory rider to come for a full season was Tadahiko Taira for Yamaha.

I didn't know Katayama came over as part of the Yamaha team, thank you for that. In '76 was he Chas Mortimer's team-mate? They were both sponsored by Sarome, I think Mortimer may have organised this for Katayama, and their leathers designs for '76 were quite similar, but the fairings designs were different and Katayama carried Hosteller (who I understand were, and still are, the Swiss Yamaha importers) stickers, while Mortimer did not, in the TT Chas rode a Danfay Yamaha that year. In '77 Katayama still had Sarome sponsorship, but he must have run out of Yamaha in Amsterdam, because he rode the 350-3 to the title that year and I am pretty sure Mortimer did not have any connection to Yamaha in Amsterdam, as in the '77 TT it looks like his sponsor was Johnsons not Sarome.

Sending riders over to Europe for a reward makes sense, I just wonder why the Japanese factories didn't want to back a Japanese rider to go for the championship. Looking at Kanaya's results I am sure he would have stood a good chance going for the title. Does anyone know if it was planned for him to do a full season in 1973 before Yamaha pulled out.

I know Takai was a semi-regular visitor to Australian races, I think he raced Bathurst on more than one occasion.

Well Kanaya was probably going to stay for the whole 1973 season as he had been chosen by Yamaha to become the 250 world champion. There was a well documented argument between Saarinen and the Yamaha management before the start of the 250 Austrian Grand Prix when he was requested to kindly let Kanaya win. During the race his pit signalled him many times to "slow", which he ignored as he wasn't going to take any orders. I'm not making this story up, it has been confirmed by Jarno's widow to at least two people I know personnally and trust. Anyway, we'll never know what the outcome would have been....

 

Regarding your comment re. Takai in Australia : yes, he certainly raced Bathurst in 1976 and 1977, and won both times ! In 1978 it was Kanaya's turn to race - and win - Bathurst . On those three occasions, Takai and Kanaya ran away with the races beating Australia and NZ's best, on a notoriously difficult track ..... admittedly, they had a definite machine advantage as their factory 750 YZR's were notably faster than the local machines - and there are some very long straights at Bathurst - but still, it was a shock for the locals. Kanaya also did the Marlboro Series of the 1977/1978 winter season in New Zealand.

 

The Japanese factories always sent their factory riders to take part in the major South East Asia races ( Singapore, Malaysia, Indonesia, Macao .....) where the potential market at the time was huge. Starting in the mid-60's with Hasegawa, Motohashi or Mimuro for Yamaha, or Itoh and Katayama (Yoshimi) for Suzuki. They also arranged for their Australian and NZ distributors to send their best riders over, to increase the prestige of those events.  Guys like Geoff Perry, Ginger Molloy, Trevor Discombe, Dale Wylie, John Boote, John Woodley or Stu Avant were "superstars" on the Asian scene at the time.

Some results data (top six) for Japanese riders in the 1970s.  I think it’s (mostly) reliable.  I have included Masato Kumano, who raced the B-2-B Sidecars in 1979, with Isao Arifuku:

 

 

Takaï also had a best result of 8th in the 500s (Sweden 1979).

Asami also had a best result of 10th in the 250s (Italy 1978, Finland 1979).

 

The other names I’ve been able to find:

K. Araoka - best result 9th, 1972 German GP 500cc

Yoshimasa or Yoshimura Matsumoto - best results 9th, 1979 Belgian GP 250cc; 10th, 1979 German GP 350cc

 

Did not score points:

Tatemo Chujero - 250cc 1976

Ken Nemoto - 250cc 1975-76-77-78, 350cc 1977-78

H. Iida - possible 125cc rider 1978......

[brands77]

Ken Nemoto was Japanese 750cc champion in 1973 and Hiroyuki Iida was Japanese 125cc champion in 1977. Both must have been pretty decent riders, to be Japanese champions, yet they didn't manage to score points in Europe at the GPs.

 

Ken is listed as qualifying on pole at the 1977 250cc Spanish GP. Could he be the only rider to qualify on pole, but never score a point?

 

For Ken in 1977 I have him finishing regularly in the teens at Spain, France and Finland in the 250cc and 350cc GPs and I know he qualified for the 350cc at the British, but retired. I only have a record of him at the British in 1978 where he finished 18th. I remember seeing Ken's bike in the paddock after the 1977 or 1978 British GP - a single TZ sitting outside a tiny pup tent, which I think he shared with a mechanic. I think it is fair to say, he did it on a shoestring! I believe he was later connected to Yamaha and writes (or wrote) a lot for their official website.

 

For Iida I have in 1976 a13th place in 250cc Finnish GP, 17th place in the 250cc Belgian GP and Swedish GP, 22nd place Czech 250c GP and 20th in the German 250cc.

 

Tatemo Chujero is shown on Wikipedia as finishing 21st (last) in the 1976 250cc Yugoslavian GP, although he is shown as qualifying 14th.

 

I also have Tako Hase finishing 20th at the German 500c GP in 1978. It looks like he rode a 354cc TZ Yamaha. I don't know anything about him, but there is a good picture of him here http://www.highsider.../Hase_78_01.htm. There are also some good photos of Asami, Matsumoto and Takai on the site http://www.highsider.com/japan.htm.

Tako Hase was living in Germany at the time I believe, he was sometimes partnering in endurance another japanese expat resident called Shimada.

 

Chijuro Tateno was often seen working as a helper/gofer in the Chevallier team. 

 

Ken Nemoto's pole position at the 1977 Spanish Grand Prix was a blatant timekeeping mistake.

 

 

Long serving Suzuki test rider Masaru Iwasaki was entered on a factory bike at the 1980 Dutch TT at Assen but failed to qualify.

 

Then of course many more came over in the 80's but that would be outside of the timeframe of this post :  Ishikawa ( who was killed practising at Le Mans) , Yatsushiro, Itoh, Taira, and of course all the wildcards which appeared at the Japan GP when it was re-instated .

The Shimada mentioned is the father of Keiki Shimada who was a regular rider in Ferry Brouwer's Yamaha Classic GP Team.
