Hokkaido is the second largest island in the Japanese archipelago, and is home to 5.5m people. Famous for ramen, seafood, and winter sports, it is also the northernmost part of Japan, and its rugged mountains and expansive plains spend much of the winter buried in snow. The population of Hokkaido is concentrated in a small number of urban centres, the largest being Sapporo with 1.8m people, leaving the vast majority of the island as a sparsely populated wilderness.
Although Hokkaido has been populated in some form or another for thousands of years, serious development only really began in 1869 with the creation of the Hokkaido Development Commission to coordinate colonisation of the region. This scenario starts 30 years later, in 1900. Many settlements have grown all over the island, in all shapes and sizes - now they need you to build an efficient transport system to connect them!
In terms of industry, Hokkaido has a wealth of raw materials in its remoter regions, but most secondary industries are located close to the main populated areas, so connecting them will be a big job. You may want to start by transporting imports from the ports to their destination, or by shipping food from the many farms to the cities that demand them.
The map is well-balanced to allow for a mix of busy urban lines, longer distance main lines connecting major population centres, and the winding rural lines Hokkaido is famous for. The mountainous terrain should help make for an interesting challenge, too.
I have placed cities by hand as accurately as I could, but with a focus on fun gameplay over realism. In particular, the population distribution is very different, and a lot of towns are larger, relative to each other, than they are in real life, in order to keep things interesting.
Screenshots: The scenario was built in OpenTTD 1.6.0. Here is the Newgrf list - they should all be easily available online:

This is my first proper scenario, so I hope people have fun with it, and welcome any feedback you can give me!

One issue you might notice with the current version is that there aren't many trees. This is because for some reason the auto-placement of trees insists on only placing trees above the snowline, and hardly ever below, as shown here: Needless to say, it looks a bit silly. I have no idea why it's doing it though - if anybody's encountered this problem before, I'd welcome any advice you can give me.
Changelog:
v0.4:
- Added several more towns around Nayoro, Asahikawa, and Sapporo which had been missed.
- Added industries.
- Added several more NewGRFs to increase the range of vehicles available early in the scenario, and replaced FIRS with the latest version (2.0.3)
- Made some modifications to the terrain, widening a few valleys etc to make it easier to recreate the Sekishou and Nemuro railway lines, which run through the mountains, connecting Obihiro to Sapporo and Furano. It would still be a fairly major feat of engineering, but should give the player a bit more flexibility in how they connect the major cities.
