Eastern Ehime: The Sacred Mountain & the Copper-Mine Frontier — 2 Days

Mt Ishizuchi is the highest mountain in western Japan and one of the seven great sacred peaks of the country, a jagged ridge of rock revered for over a thousand years and still climbed by white-robed pilgrims who haul themselves up its famous chains to the shrine on the summit. The ropeway climbs the lower mountain in about eight minutes, lifting you from the valley to around thirteen hundred metres, where a short walk reaches a mountain shrine, an observation point and, in autumn, some of the earliest and finest colour in Shikoku. Reaching the true summit is a serious half-day climb beyond the ropeway and not part of this route; the cable car alone gives the scale, the air and the sacred atmosphere of the peak, and is the high point of the eastern day. Check the seasonal timetable before setting out.

Ropeway round trip about ¥2,200 (approx., 2026); runs year-round on a seasonal schedule, first and last cars vary. Reached by bus from Iyo-Saijo Station. Allow about 180 minutes including travel and time at the top.

Down from the mountain, Saijo is the place for lunch, and the town's pride is its water: Saijo sits on the snowmelt of Ishizuchi, which surfaces all over the city as 'uchinuki', cold, soft artesian water that pours from hundreds of free wells and is rated among the best in Japan. That water makes the local rice, sake and noodles, and the town eats well and simply — udon and soba in the clear local broth, river fish, and the vegetables of the Saijo plain. After a morning on the mountain it is an easy, restorative meal in the water city, and a good moment to fill a bottle from a roadside spring before walking the town in the afternoon.

A meal about ¥1,000-1,800 (approx., 2026); restaurants generally 11:00-15:00. In central Saijo. Allow about 60 minutes.

Saijo's defining wonder is its 'uchinuki', the free-flowing artesian springs that rise of their own pressure all through the city — in parks, beside roads, in courtyards and even in the middle of the river, where freshwater wells up through the seabed offshore. Fed by the snow and rain of Mt Ishizuchi filtering down through the plain, the water is cold, soft and exceptionally pure, and has been chosen among Japan's finest waters; townspeople fill bottles and tanks from the public taps every day. Walking from spring to spring with a cup, tasting the difference between one well and the next, is the quiet pleasure of Saijo and a side of Japan — a whole town organised around clean water — that few visitors ever see.

Free; public springs open continuously, a visitor centre helps locate them. In central Saijo. Allow about 40 minutes.

Beside Iyo-Saijo Station, the Railway History Park gathers the Shikoku Railway Cultural Center and the memorial museum of Dr Hideo Shima, the Saijo-connected engineer who led the design of the first Shinkansen bullet train. Its halls hold the real machines: an original 0-series Shinkansen car, the rounded nose that became the face of modern Japan, displayed beside a DF50 diesel locomotive and other rolling stock you can climb into and sit in the cab of. For a solo traveller with an eye for how things are made and run, it is a genuinely absorbing stop, and it ties the day's industry-and-engineering thread to the morning's water and mountain. Note it closes on Wednesdays, so keep this day off mid-week.

Admission about ¥300 (approx., 2026); roughly 9:00-17:00, closed Wednesdays. By Iyo-Saijo Station. Allow about 60 minutes.

Lodging in the eastern end of Ehime is business-hotel territory — clean, reliable, functional and without pretension — and a hotel like the Route Inn by Iyo-Saijo Station is exactly the right base for this route. There is no ryokan or resort tier out here, and the honest pleasure is a comfortable room, an artificial hot-spring bath to soak the mountain out of your legs, and a quiet night in a working provincial city before the copper-mine country tomorrow. For the independent traveller it does everything that is needed and gets out of the way; the experience of this route is on the mountain, in the springs and down the mine, not in the hotel.

Rooms business-tier, with an artificial hot-spring bath (approx., 2026). By Iyo-Saijo Station. Check in and settle, about 30 minutes.

The Besshi copper mine above Niihama was worked from 1691 until 1973 — nearly three centuries — and it was the foundation of the fortune of the Sumitomo house, one of the great industrial dynasties of Japan. Minetopia Besshi is the heritage park built on the main lower works at Hadeba, where a little mine railway carries visitors across a red iron bridge and into a tunnel to a recreated mine gallery, with the brick remains of the old power station and ore-dressing plant around it and a hot-spring bathhouse on site. It is an engaging, hands-on introduction to a vast industrial story — how a mountain of copper was dug, hauled and smelted — and the natural first stop of the copper-mine day.

Park with mine train about ¥1,300 (approx., 2026); roughly 9:00-18:00 (seasonal). Above Niihama, reached by car or bus. Allow about 90 minutes.

High in the mountains above the main works, at around seven hundred and fifty metres, lies Tonaru — Higashidani — the upper zone of the Besshi mine where a whole working town once stood, with a station, a school, shops and the families of the miners, all reached by an inclined railway up the slope. The town is long abandoned, and what remains is a haunting terrace of moss-grown stone walls, ruined ore-dressing steps and tunnel mouths returning to the forest, sometimes called the 'Machu Picchu of the East' for its scale and its setting. A small museum tells the story of the people who lived here. It is remote, seasonal and weather-dependent, so confirm access before going, but for the solo traveller it is the unforgettable, slightly melancholy heart of the copper-mine country.

Free to view; small museum modest fee; access seasonal and mountain road, confirm open days (approx., 2026). Above the Hadeba zone. Allow about 60 minutes.

Back down in Niihama, the industrial city built by the copper money, take lunch before the last stop. Niihama is a working town rather than a tourist one, and it eats accordingly — hearty local plates, sea fish from the Inland Sea, and the regional specialities the city is fond of, with good casual restaurants around the station and the centre. It is an unpretentious, satisfying meal in a place few foreign travellers ever stop, very much in keeping with the honest character of this eastern route, and the fuel for a last hour at the museum before the road home. Niihama also throws one of Ehime's three great festivals each October, when towering drum floats fill these streets.

A meal about ¥1,000-1,800 (approx., 2026); restaurants generally 11:00-15:00. In central Niihama. Allow about 60 minutes.

The Akagane Museum — 'akagane' is the old word for copper — is Niihama's cultural centre, a striking contemporary building clad in copper that has weathered to a deep red-brown, standing near the station as a monument to the metal that made the city. Inside it gathers the art and history of Niihama and, most memorably, a hall devoted to the great Niihama Taiko festival, with one of the towering 'taikodai' drum floats on display so you can grasp the astonishing scale of the things — some five and a half metres high and weighing two and a half tonnes, hauled through the streets by teams of men each October. It is a fitting last stop, drawing together the copper, the craft and the living culture of the eastern cities before the journey home.

Building free; some exhibits ticketed (approx., 2026); roughly 9:00-17:00. By Niihama Station. Allow about 60 minutes.
