There are only 3 Japanese routes in Train Simulator, one of which is a fictional route. These routes are all set in mostly rural/semi-rural areas and feature a simple local commuter service. Now that's fine. I love the Wakayama-Sakurai and Hidaka Main Line routes as they feature excellent scenery and well detailed trains. However, Japanese trains aren't just about scenery, they're also about speed. The first thing most people think of when you mention a Japanese train is the Shinkansen or "Bullet Train" as it's known in the west. The Tokaido Shinkansen line opened on October 1, 1964 as the world's first high speed train service between Tokyo and Osaka. Since then, the Shinkansen has branched out to cover most of Japan, with the Sanyo Shinkansen opening between 1972 and 1975, the Tohoku and Joetsu Shinkansen opening in 1982, the Yamagata Shinkansen opening in 1992, the Akita and Nagano Shinkansen in 1997, the Kyushu Shinkansen in 2004, the Tohoku extension to Shin Aomori in 2010, the Hokuriku Shinkansen (Nagano-Kanazawa) in 2015, and most recently the Hokkaido Shinkansen in 2016. I am aware that a section of the Sanyo Shinkansen was attempted in TS, which ran from Osaka to Okayama and featured the 300 Series Shinkansen train. However last I heard, the route was never completed and the project was scrapped before it could be released. My proposal is to make the approximately 226 km section of the Hokuriku Shinkansen from Tokyo to Nagano. The reason why I'm proposing this as opposed to a section of another Shinkansen line like the Tokaido or Tohoku Shinkansen, is because on this section, you can run a complete service from start to finish. Other routes like the Tokaido Shinkansen are too long to make the entire route in TS. The Asama service runs from Tokyo only as far as Nagano and was the original service that ran back when the line terminated at Nagano. This service stops at nearly all stations along the way. Stations in this route would include Tokyo, Ueno, Omiya (where the Tohoku Shinkansen diverges), Kumagaya, Honjo-Waseda, Takasaki (where the Joetsu Shinkansen diverges), Annaka-Haruna, Karuizawa, Sakudaira, Ueda, and Nagano. Speed limits along the route average mostly at 260 kph (about 160 mph) and the trip usually takes anywhere from 90 to 140 minutes. The route passes through many different types of scenery, including picturesque mountains, sprawling suburbs and rice paddies, and the modern urban super-metropolis of Tokyo. 2 types of trains are used on this route. The E2 Series (8 car sets introduced in 1997) and the E7/W7 Series (12 car sets introduced in 2014). I would suggest including both to give players a little variety, however if you can only include one, I'd pick the E7/W7 sets, since they're now the only trains running on the route (the E2 sets were withdrawn from the Hokuriku Shinkansen Asama services in March of 2017). The Shinkansen desperately needs to be represented in TS and I think the Tokyo-Nagano route would be the perfect way to do it, at least for a start.
