Yasu Tanaka has a lot of models of Formula 1 racing cars, mostly from the late 1990s and 2000, and two from the 1970s. He also has a Lamborghini car and a motorcycle - the diminutive Honda Motocompo from the 1980s.
He has also designed models for others, some of which are mentioned on his site, but hosted elsewhere. There are three simple models for Nippon Paper Industries, which appear no longer to be available, and two ski resort snow-grooming machines for Ohara Corporation. One of the NPI models is also a motorcycle, but a very simple model of free-lance design, which is really not very interesting.
It is disappointing that he appears to have moved away from paper models, as the web site has not changed since 2004, and the most recent models are from 2003.
