I posted a general overview of Shinkansen trains in Japan in the general "The Ready Track" forum. Here I will post about N-scale models. Japan has two large model companies that make N-scale trains, and 2 smaller companies that also compete in the area. There may be smaller specialty ones as well, but these 4 make up the major n-scale manufacturers in Japan. Tomix (Tomytech -- the TOMY company) and KATO are the major players. KATO of course also is a major player for US model trains and is also a player in Europe (where there stuff is sold by Lemke and NOCH for European trains, mostly HST (Lemke) or Swiss trains (NOCH), and also imported by European shops for the Japanese and US stuff). Tomix is mainly Japan only in terms of model trains (but TOMY is a major toy company worldwide). Greenmax and Micro Ace are the two smaller players. I don't know if Greenmax has done Shinkansen, but Micro Ace has done some Shinkansen. Being smaller, they tend to make models of smaller lines, or of variants not done by the majors. For example, Micro Ace makes the JR East inspection train Shinkansen, which Tomix and KATO don't (while KATO does make the JR Central inspection train Dr Yellow). Both Tomix and KATO typically will make versions of the same trains. You can get an N700A from both, or an E5 from both. Both manufacturers make good models and have characteristics that make them unique (and in their fans' eyes, better). Tomix Shinkansen (but not their non-Shinkansen models in most cases), have all-train power pickup -- the wagons share power throughout the train to help avoid drop outs from dirty track etc -- when you have 8, 12, or even 16 cars all picking up power, they are unlikely to all suffer a dropout at the same time). KATO is usually DCC friendly (but not all of them are). There are other differences as well between them, both pro and con. (Tomix does not know the word DCC, though I have upgraded Tomix Shinkansen with wired decoders and HOW-TO will be eventually on my blog). The first picture I would like to post is of my 500 series trains. The Shinkansen 500 series were made by JR West and first used as Nozomi trains. They were at one time the fastest Shinkansen. They did however have some weaknesses which lead to their being demoted early in their life. They are still used today in Kodama service and in special liveries as well (as Kodama). One shortcoming is that while fast on the straight track, they had to slow down more to go through curves than other Shinkansen. Also, having a round, circular cross section, they were not as spacious inside. I own 3 different Shinkansen 500 models (technically I own two, and my daughter one). I have a KATO Nozomi Shinkansen 500, but only 8 cars worth. Nozomi run as 16 car trains. The Kodama version of the 500 is an 8 car train, so I call mine a Kodama , but I think that the Kodama trains have been reorganized so that the actual 8 cars I have would not match the 8 cars run. But normal folks would not see the difference. It is gray with blue. I also have the KATO Neon Genesis Evangelion (EVA) special livery 500, which ran as a Kodama from Nov 2015 through May 2018. I regret that I did not get a chance to ride this train in real life, despite being there in both Dec 2015 and 2017. I did not, at the time, know of its existence. The KATO version of the EVA 500 is not prototypically correct, as I understand it, as they just repainted Nozomi cars or something. Technically the Tomix version is supposed to be more prototypical. My daughter owns the Tomix Hello Kitty Shinkansen 500 (Kodama). JR West took the EVA Shinkansen, after it was withdrawn, and re-painted it in a fun Hello Kitty livery and ran it for a few months in Kodama service. Both the EVA and Hello Kitty trains also had special exhibits, and other bits inside the train for the riders to experience.
