Toyota's 2000 GT was the first Japanese "sports car" comparable to what was being offered in America at the time so it is one of the most collectible Japanese cars. Toyota's Supra is also considered a collectible due to its limited production run in America and its uniqueness.
Datsun had several models which could be considered "collectibles" and they include: the 240Z, the 260Z, the 280Z, the 300Z (all versions in fact), and the 510.
Datsun later became Nissan and produced the Skyline and the Fairlady, all models of both are considered collectibles especially in the U.S. due to the fact that none of which are no longer produced, and the Skyline was never sold in the U.S.
Honda has had many, many racing vehicles which would be considered milestones in the Japanese automotive industry. Check out the Honda museum in Japan online and you'll see just how many truly collectible Hondas there are.
Mazda's rotary powered vehicles including the RX7 are all collectibles due to similar circumstances as the Skyline and the Fairlady, as well as the Supra (all the Japanese supercars of the 90's could be considered collectibles due to their rarity).
Mitsubishi's Lancer Evo could be considered a collectible in the U.S. due to the fact that it was never released as a U.S.D.M. model until the Lancer Evo VIII. The 3000GT (especially later models like the '99) are definitely collectibles due to the fact that they had a limited production run their last model year and sold like hot cakes.
Subaru's Impreza (especially WRX/STi models) is a collectible in the U.S. once again due to the fact that it wasn't released in the U.S. as a U.S.D.M. model until just recently utilizing the TAGDA chassis.
I could keep going but I'll spare you all the tedium of reading anymore
