Minetopia Besshi Copper-Mine Heritage Park, Ehime

Seasons and floral highlights

Minetopia Besshi (マイントピア別子) is organised around outdoor gardens and a lawn plaza whose plantings change through the year. The site lists species such as Soshin robai, mountain cherry, sato-zakura and Somei-Yoshino cherry alongside mitsumata and sanshuyu. Specific seasonal blooms named in the site information include peony and salvia in May, hydrangea in June and Kanokoyuri lilies in July. The flower garden and seasonal plantings are one of the visible ways the park changes across months.

Hadeba Zone — the hub of visitor facilities

The Hadeba Zone occupies the river-valley section reached from Niihama along Ehime Prefectural Route 47 (the Niihama–Besshiyama line). The main building houses Besshi Onsen “Tenku no Yu”, a kids park, food and souvenir corners, and an event/display hall that shows children’s taiko-float exhibits.

On the second floor of the main building is Hadeba Station, the boarding point for a short tourist railway whose track is roughly 400 metres long; a one-way ride takes about three to four minutes and links the main building to the mining-tourism area. In the mining area a former explosives magazine has been converted into a tourist tunnel of 333 metres where displays recreate scenes of the Besshi Copper Mine in both the Edo period and the modern era.

The train that runs the line is an electrically driven, slightly reduced-scale reproduction of the Sumitomo Besshi Mine Railway steam locomotive known as “Besshi No.1.” The original mine locomotive from the Besshi operation is on static display in front of the Besshi Copper Mine Memorial Museum. The tourist train was renewed on 1 March 2019, when cage cars and handcars were connected to give a configuration closer to historic trains.

Outside the building the zone includes a gold-panning area, a barbecue cafeteria, seasonal flower beds and an event lawn. The Hadeba Zone opened as a copper-mine theme park on 5 June 1991; the place had earlier been the site of the mine’s last mining headquarters after that office moved from the mountain base in 1930.

Tounaru Zone — the mountain mining centre

The Tounaru Zone sits higher on the mountain at roughly 750 metres elevation and preserves the facilities that supported mining life at altitude. After the mining headquarters moved to Hadeba in 1930, Tounaru continued to be active until the mine’s closure in the later 20th century; the article notes that the area remained lively until 1968.

Facilities developed for interpretation include the Tounaru History Museum and the Mine Workshop, which uses the old brick-built security head office for hands-on copper-plate relief work. Numerous industrial ruins and structures are maintained: an incline track now used as a 220-step stair, short and long pump tunnels turned into exhibition spaces, and the third main transport tunnel (Third Tunnel) completed in 1902 at 747 metres elevation with a length of 1,795 metres (width 3.35 m, height 3.73 m). The zone was promoted with the phrase “Eastern Machu Picchu” in visitor materials and is listed as number 65 in the compilation of Shikoku 88 scenic spots. A route into the Tounaru Zone that had been closed because of a landslide was reopened on 1 April 2023 after work.

Historic structures and industrial archaeology across the site

Minetopia Besshi is built on the remains of the Besshi Copper Mine and preserves a number of registered structures and notable industrial features. Examples recorded in the site material include:

• The former guest entrance and a special guest room from Izumujutei, originally built in 1937 in Kita-Shinmachi and relocated to the park in 1991; this structure was registered as a tangible cultural property on 7 August 2009 and is described as Kyōfū sukiya-style architecture that visitors may enter.
• The former Hadeba Hydroelectric Power Station, completed in 1912 and registered as a tangible cultural property on 26 January 2011; the station retains original generators and equipment and the interior has been opened for public viewing free of charge from 28 March 2023.
• The water-pressure pipe system that linked mountain reservoirs to the power station: the stone records note 236 iron pipes and a head difference of 597.18 metres that allowed large-scale generation with a relatively small water flow.
• Railway relics used by the tourist line today, including the Ashidani River truss bridge (built in 1893 by the German firm Harkort) and the Nakao Tunnel (length 92.55 m, width 3.0 m); both were registered as tangible cultural properties on 7 August 2009.

Other industrial remains include the Hadeba ore-storage site (completed 1919), the Fourth Tunnel (completed in 1915; elevation 156 m, length 4,596 m), and the large incline and coarse-ore bin area where the incline reached a slope of about 15 degrees, an extension of 4,455 metres and levels approaching one thousand metres below sea level; a coarse-ore bin with a capacity of 4,000 tonnes is recorded at the site and still visible on the opposite mountainside.

The Shakamori company housing group lies above the large north parking area; at its peak about 300 houses housed around 1,300 employees and family members. The housing cluster was built from 1916 onward and closed in March 1970; a central stairway of 277 stone steps leads up the slope.

Roadside station (Michi-no-Eki) and practical access

The site includes Michi-no-Eki Minetopia Besshi on Ehime Prefectural Route 47 at Tachikawa-chō; it was registered among the first roadside stations in 1993. Parking capacity is listed as 381 ordinary cars, 13 large vehicles and 7 disabled spaces. Toilet counts in the official specification show men’s fixtures (large 12; of which 4 are in the separate 24‑hour block) and small 36 (11 in the 24‑hour block), women 30 (10 in the 24‑hour block), and 3 accessible toilets (1 in the 24‑hour block). A public telephone and a pair of small vendor huts stand by the main parking area; the vendor space called Nakamochi Chaya lists “iyokan soft cream” as a noted offering.

Access notes in the site material give concrete routes: from JR Niihama Station take the Setouchi Bus or the Besshiyama regional community bus; by car the run is about 15 minutes and a large free parking area serves the park. To reach the Tounaru Zone from the Hadeba Zone the road follows Prefectural Route 47 4.7 km south, turn left before Shigure Bridge and continue a further 5 km (the article gives the subsequent drive as about 30 minutes). The Hadeba Zone runs six microbuses to the Tounaru Zone as a two-hour sightseeing course; the park’s notes say weekend operation can run from a single passenger and that smaller weekday groups below five people may not be served, with telephone reservations possible for charter use.

Nearby Old Besshi and name origin

Beyond the two main zones, an area called Old Besshi on the southern side of the Akaishi range contains further industrial heritage. From the Hadeba Zone the Old Besshi trailhead lies about thirty minutes farther south on Prefectural Route 47, immediately past Besshi Dam; the Old Besshi parking area listed in the material holds nine cars.

Local tradition recorded with the site links the place-name “Besshi” to an early historical narrative: descendants of a son of Emperor Keikō who governed the Iyo area in the early fourth century are named as ancestors of the families who ruled the district, and the name “Besshi” is said to have arisen from that lineage.

A commercial experiment recorded in the site material: in 2016 a venture began rearing warm-spring tiger puffer (torafugu) in four tanks on the Minetopia grounds and explored serving it in on-site restaurants; that effort was discontinued in November 2018 owing to poor growth.
