• JR Senmo Line: A railway line in eastern Hokkaido connecting Kushiro to Abashiri, passing through three national parks.
• Kushiro Shitsugen National Park: Japan's largest marshland and a sanctuary for diverse wildlife.
• Red-crowned Crane: An endangered bird species central to the conservation efforts in the Kushiro region.
• Akan Mashu National Park: A volcanic region featuring crystal-clear lakes and active geothermal activity.
• Shiretoko National Park: A UNESCO World Heritage Site known for its rugged terrain and drift ice ecosystem.
• Drift Ice (Ryuhyo): Sea ice that travels from the Amur River in Russia, creating a unique biological foundation for the Sea of Okhotsk.
• Steam Locomotive Heritage: The preservation and repurposing of historical 1940s steam engines for tourism.

The Journey via the JR Senmo Line

The journey traverses approximately 170 km of eastern Hokkaido, starting in Kushiro and ending in Abashiri. The route is characterized by its passage through three distinct national parks and its deep connection to the region's volcanic and railway history.

Kushiro and the Steam Locomotive Experience

Kushiro, located nearly 1,000 km north of Tokyo, serves as the starting point. With a population of 150,000, its economy is historically rooted in rich fishing grounds.

• The Steam Locomotive: A locomotive built in 1940, which was once retired to a park but was brought back into service in 2000 due to local resident lobbying.
• Passenger Amenities: The train features five passenger cars with large windows and outward-facing seats designed for sightseeing. A notable feature is the onboard coal stove, which passengers use to roast local snacks like dried squid and crab.

Kushiro Shitsugen National Park: Wildlife and Local Craft

As the train moves through Japan's largest marshland, it enters a sanctuary for over 250 animal species.

• Conservation of the Red-crowned Crane: Once facing extinction, recent conservation efforts have successfully restored their numbers. The station at Kayanuma, though now unstaffed, holds historical significance because former staff members used to feed the cranes to aid their survival.
• Artisanal Soot Crayons: At Toro Station, artisan Iwaki Tomoko produces unique crayons using natural ingredients.
  • Methodology: The process involves melting beeswax and adding powdered pigments derived from local plants, soil, and Manchurian walnuts.
  • Technical Detail: The crayons utilize soot from the steam locomotives. The color varies based on temperature: soot from the smoke stack is pitch black, while soot from the boiler is gray. The production process takes approximately three weeks.

Shibecha Station and Railway Culture

Shibecha Station serves as a historical landmark, having once been a vital depot for servicing, fueling, and supplying steam engines.

• Railway-Themed Gastronomy: To appeal to railway enthusiasts, local cafe proprietor Watayama Mami created a signature dish: curry and rice topped with Hokkaido-style fried chicken that has been stained black with squid ink to resemble lumps of coal.

Akan Mashu National Park: Volcanism and Agriculture

The second leg of the journey enters a region shaped by volcanic activity.

• Lake Mashu: Recognized as one of the clearest lakes in Japan, it is known for its vivid blue color on sunny days and its tendency to capture ethereal fog.
• Mount Iou (Sulfur Mountain): An active volcano that powers the local onsen (hot springs). The name "Iou" refers to the sulfur crystals that give the mountain its yellow hue.
• Historical Economic Link: The Senmo Line's existence is tied to the sulfur mining industry, which peaked before 1963 when sulfur was exported to America and China.
• Geothermal Agriculture: The heat from Mount Iou is utilized in greenhouses to grow tropical fruits, such as mangoes. This allows for internal temperatures to remain above 20°C even when external temperatures drop below -20°C.

Shiretoko National Park: The Drift Ice Ecosystem

The third national park is a UNESCO World Heritage Site characterized by the Shiretoko Range and its unique marine biology.

• The Drift Ice Ecosystem: Ice drifting over 1,000 km from the Amur River carries plankton, which supports a food chain of tiny fish, larger fish, and apex predators.
• Notable Fauna:
  • Stellar's Sea Eagle: An endangered species frequently seen surveying the ice.
  • Blakiston's Fish Owl: An extremely rare species, with only about 1,000 remaining in the world.
  • Other species: Spotted seals, Ezo Shika deer, brown bears, and Ezo red foxes.
• Guided Exploration: Due to the rugged terrain, guides are recommended for hiking to prevent accidents in the dense forest.

Abashiri: The Final Destination

The journey concludes in Abashiri, a major hub for drift ice tourism, attracting approximately 600,000 visitors each winter.

• Railway Enthusiast Accommodation: The trip ends at a wooden inn managed by Kōriyama Takuya.
• Interactive Railway Experience: Through crowdfunding, Kōriyama acquired a rare, small engine that previously only operated within rail yards. He installed 70 meters of track in front of the inn, allowing adults (over 18) to drive the engine for 30-minute sessions.

Synthesis and Main Takeaways

The JR Senmo Line is more than a transport route; it is a corridor that connects Japan's industrial history with its most delicate natural ecosystems. The journey highlights a symbiotic relationship between human activity and nature: the railway was built to transport sulfur, the steam engines provide the pigment for local art, and the volcanic heat enables tropical agriculture in sub-arctic climates. The preservation of both the steam locomotives and the endangered wildlife (like the red-crowned crane and Blakiston's fish owl) underscores a regional commitment to maintaining cultural and biological heritage.
