Company history

Tobu Railway was incorporated in November 1897 with capital of ¥2.65 million to link Tokyo with the northern Kanto plain, and opened its first stretch of the Isesaki Line — Kita-Senju to Kuki — in August 1899. It then stalled. Land acquisition proved difficult, traffic along the line was thin, and the railway could not reach the towns of Gunma and Tochigi that were supposed to fill its trains, because the Tone River cut the route in two.

In 1905 Nezu Kaichiro, a speculator and industrialist from Yamanashi, bought into the stock and took a hand in management. He stripped out internal waste and, at the same time, spent roughly ¥400,000 on a 549-metre bridge across the Tone — an extraordinary sum to concentrate on a single structure — and pushed the tracks north. That one decision set the scale of the company. The Isesaki Line was completed in 1910; Sano Railway followed in 1912 and Ota Light Railway in 1913; the 1920 merger with Tojo Railway added the Tojo Line and gave Tobu the two-trunk structure it still runs on. When the Nikko Line opened through in 1929, Tobu became the first private railway in Japan to run electric trains over more than 100 kilometres — the ancestor of the Spacia and Spacia X limited expresses, and the foothold for its leisure business. Real estate was expanded in the same year, pairing the railway with development of the land beside it.

The Asakusa terminal opened in 1931, connecting the network to what was then Tokyo’s largest entertainment district. Wartime consolidation did the rest: Joshu Railway in 1937, Shimotsuke Electric and Ogose Railway in 1943, Sobu Railway — the basis of today’s Urban Park Line — in 1944. The result was 463.3 route-kilometres, the largest private network in Kanto and, nationally, second only to Kintetsu. Nezu Kaichiro died in 1941 and his son, Nezu Kaichiro II, took the presidency — and held it for about fifty-three years. Tobu listed on the Tokyo Stock Exchange in 1949, and moved into retail with Tobu Utsunomiya Department Store in 1958 and Tobu Department Store and Tobu Kaikan (now Tobu Store) in 1960.

In May 1962 the Isesaki Line began through-running onto the Teito Rapid Transit Authority’s Hibiya Line (today’s Tokyo Metro), putting Ginza, Roppongi and Ebisu within a single ride of Kita-Senju. The reasoning was arithmetic: laying Tobu’s own rails into central Tokyo would have meant enormous land and construction costs, while running onto an existing subway delivered the same convenience with no new track to carry. Nezu Kaichiro II had said as much before the service opened — “the line will be joined directly to the city centre, so it will develop enormously; the paddy fields will be filled in and become housing.” They were. Suburbanization along the Isesaki Line ran through the 1960s and 1970s, and commuter traffic lifted both the railway and the property business. Tobu was assigned to the First Section of the Tokyo Stock Exchange in October 1961.

Through-running to the Yurakucho Line via Wako-shi followed in August 1987, opening the Tojo Line to Yurakucho and Shintomicho. Across those twenty-five years a policy hardened: rather than extend its own network, Tobu would create junctions with other people’s and let the connection raise the value of its own corridor — holding down capital spending on rail infrastructure while capturing the network effect, and monetizing the resulting suburbanization through property and retail.

The other half of the model was to put shops where the trains ended. Tobu Department Store’s Ikebukuro branch opened on the west side of the station in May 1962 — the same month as the Hibiya Line link — turning the Tojo Line terminal’s passenger flow straight into shop-floor traffic. Railway, retail and real estate were run as one business, so that a passenger paid Tobu twice: once for the house in the suburbs and once at the store downtown. That this combination could be assembled at all owed much to family control: rail, property and department stores all return capital slowly, and a single president in office for fifty-three years was not going to be pushed off them by a bad half-year.

In 1990 Tobu Department Store moved to buy the American luxury retailer Saks and was outbid by Investcorp at $1.5 billion — a defeat that brought a policy split between the owning Nezu family and the store’s management into the open and cost the department store its president. The group turned inward instead. An enlargement of the Ikebukuro store was completed in June 1992 at 82,963 square metres of selling space, the largest in Japan, aimed squarely at the Seibu department store on the east side of the station; with the surrounding west-exit redevelopment, Tobu committed roughly $710.5M (¥90bn). It was called the group’s “greatest and last challenge.” The bubble burst as it opened. Floor area did not convert into customers, the department store format itself went into decline through the 2000s, and in October 2001 Tobu restructured the business by transferring 1,500 employees to subsidiaries and taking 150 voluntary retirements. The store stayed in the group as a device for filling the terminal — but the west exit of Ikebukuro was still an unfinished redevelopment project three decades later.

The second bet ran the other way. When Tokyo needed a 600-metre tower for terrestrial digital broadcasting in 2003, ten candidate sites were narrowed to a disused freight yard beside Oshiage station — land Tobu already owned, in a ward that wanted it, next door to the tourist traffic of Asakusa. Tobu invested about $1.8B (¥143bn) in the whole Skytree Town and set itself a 25-year payback, an unusually long horizon for a single private-railway project. Tokyo Skytree opened in May 2012 and the tower alone earned an operating profit of about ¥9.1 billion in its first year; the leisure segment swung from a ¥620 million loss in the year to March 2011 to ¥10.6 billion of profit in the year to March 2013. Where the 1992 store enlargement had been a thirty-year drag, an investment of comparable size twenty years later beat its own plan.

Through-running kept widening: the Hanzomon and Tokyu Den-en-toshi lines in 2003, the Fukutoshin Line in 2008, the Tokyu Toyoko and Minatomirai lines in 2013, and in March 2023 a Tojo Line service reaching the Sotetsu network via the Shin-yokohama Line — five operators and fourteen lines strung together, with Tobu holding a central position in the metropolitan rail web without having built the track. In the year to March 2019 operating revenue reached ¥617.5 billion and recurring profit ¥62.9 billion: transport ¥213.6 billion of revenue and ¥41.1 billion of operating profit, leisure ¥76.2 billion and ¥6.0 billion, real estate ¥45.1 billion and ¥14.0 billion. Three pillars each earning at the ten-billion-yen scale — that was Tobu on the eve of the pandemic.

The pandemic took the commuter and tourist traffic that all three pillars rested on, and the recovery ran alongside a change Tobu had never made before. In March 2023 the Tojo Line began through-running to the Sotetsu network via the Shin-yokohama Line, completing the connective strategy begun in 1962; three months later, in June 2023, Nezu Yoshizumi handed the presidency to Tsuzuki Yutaka, a career Tobu manager, ending about 120 years and three generations of Nezu leadership.

He chose it himself. “There are limits to hereditary succession within one family,” he said. “I am the last president from the Nezu house.” The reasoning was that a family cannot guarantee a suitable successor in every generation, and that a Prime-listed company is better served by professional management under transparent governance than by continuing the line. Tobu set up nomination and remuneration committees and separated the board from executive officers to match. What the family leaves behind is the habit of very long-dated capital allocation — and its unfinished business: the redevelopment of the west exit of Ikebukuro station, still on the investment agenda thirty years after the bet that created it.
