Where it sits
A former coal city of around 9,000 people, in the Sorachi Sub-prefecture of central Hokkaido. The city peaked at 59,430 residents in 1960; today it is dignified, half-empty, and surprisingly well-served by national-route infrastructure.
It is not Niseko. It is not Furano. It is the kind of place from which you can get to those tourist gravity wells — but where land, buildings, and labor cost a small fraction.
Climate
Central Hokkaido sits squarely in Japan's heavy-snow belt. Annual snowfall regularly exceeds two metres. Winters are cold, dry, and long; summers are warm, dry, and short. The shoulder seasons are unusually beautiful — Akabira's surrounding hills are covered in maple and beech.

JR Akabira Station, walking distance from the property. Local Nemuro-Hakodate line connectivity, with limited express transfers in Iwamizawa.
The castle is on Route 38 itself. The road runs all the way to Kushiro on the Pacific coast — useful for anyone moving inventory east.
Embedded Google Map. The castle is on the southern edge of town, on the National Route 38 frontage, with the Sumitomo zuri-yama visible to the north on a clear day.
