Mizuma Railway Mizuma Line

The railway was promoted by local backers in Kaizuka, then a town prospering on the spinning and textile trades, who raised the subscriptions for an entirely private, locally financed company. A licence to build a railway was applied for and granted on 8 August 1923 under the provisional name Mizuma Steam Railway, covering a route in Sennan District, and the Mizuma Railway Co., Ltd. was formally established on 17 April 1924 with capital of 400,000 yen.

The line opened in stages. On 24 December 1925 the first section, from Kaizuka-Minami (貝塚南, later renamed Umizuka) to Nagose, was opened; a short freight branch between Nankai's Kaizuka Station and Kaizuka-Minami followed on 28 December 1925, beginning freight operations. The remaining section from Nagose to Mizuma — the present Mizuma Kannon — opened on 30 January 1926, completing the line through to the temple. Passenger service over the Kaizuka–Kaizuka-Minami stretch began on 20 January 1934. The terminal station building at Mizuma Kannon, in use since the 1926 completion, was designated a Registered Tangible Cultural Property of Japan in 1999.

Through the post-war decades the line settled into a steady local existence, carrying inland Kaizuka residents and, around 1970, some 3.8 million passengers a year. Freight operations were discontinued in 1972, and the line's block system was converted from tablet to automatic operation in 1985. In 1990 the overhead voltage was raised from 600 V to 1,500 V DC, and the entire fleet was replaced with former Tokyu 7000 series electric cars, built between 1962 and 1966, which the company acquired from the Tokyu Corporation; ten cars were taken on, and from 2006 they were progressively refurbished and renumbered as the 1000 series, of which four two-car sets remain in service.

During the boom years of the 1980s the company expanded aggressively into real estate beyond the railway, at its peak turning over around two billion yen, but that business collapsed after the bursting of the asset-price bubble, leaving heavy borrowings that weighed on the company; with passenger numbers also falling, the Mizuma Railway gave up on self-rehabilitation and on 30 April 2005 filed for protection under the Corporate Reorganization Act at the Osaka District Court — a corporate insolvency. (Reported liabilities differ between sources, from about 14 billion yen to about 25.8 billion yen.)

The rescue came from outside the railway industry. On 30 June 2005 the restaurant chain Gourmet Kineya was selected as the sponsoring company; its chairman, Hikoyuki Mukumoto, had been evacuated to Kaizuka as a child during the war and stepped forward to support the railway's rebuilding out of that connection. Reconstruction proceeded under Gourmet Kineya's wing: on 6 April 2006 it acquired 100 percent of the shares, making the Mizuma Railway a wholly-owned subsidiary, and on 16 June 2006 the Osaka District Court ruled the reorganization plan concluded, completing the corporate-reorganization process and relaunching the firm as a new company.

Under the new ownership the railway modernised its fare collection and reaffirmed its founding purpose. It joined the Surutto KANSAI council in 2007 ahead of introducing IC cards, and on 1 June 2009 brought in the PiTaPa IC card, shifted the whole line to one-man operation, and renamed Mizuma Station as Mizuma Kannon Station; nationwide IC-card interoperability followed on 23 March 2013. Reflecting the line's origin as a pilgrimage railway, the company has long run extended late-night and, formerly, all-night services on New Year's Eve to carry hatsumōde worshippers to Mizuma-dera, the temple at its terminus that gave the railway its reason to exist.
