History
The Seishin Line was conceived as the trunk artery serving Suma New Town, a planned residential district then being developed in western Kobe. It was the first municipal subway built in the city, and it runs partly in the open: the stretches around Myōdani and Myōhōji stations are at the surface, with Myōhōji half-underground. From the outset the project was planned as part of a longer corridor that would eventually reach the Shin-Kobe Shinkansen station to the east.
Authorisation came in the early 1970s. On 15 October 1971 the Ministry of Transport granted the Kobe Municipal Transportation Bureau a railway-business licence for a subway line linking the Myōdani district with Shin-Kobe, and construction of the first segment, between Shin-Nagata and Myōdani, followed. The line's 1000-series rolling stock was completed at Kawasaki Heavy Industries on 23 February 1976 in readiness for the opening.
The Shin-Nagata–Myōdani section opened on 13 March 1977, becoming the first municipal subway line in Kobe; the 1000-series entered revenue service the same day. The opening established the core of what would grow into a much longer route, and work to extend it toward the city centre began the same year, with construction of the Shin-Nagata–Ōkurayama section starting on 17 December 1977.
Through the 1980s the Seishin Line became the middle link of a steadily lengthening subway. The Yamate Line was built eastward from Shin-Nagata: the Ōkurayama–Shin-Nagata segment opened on 17 June 1983, and on 18 June 1985 the Shin-Kobe–Ōkurayama segment was completed, joining the line to the Shinkansen interchange at Shin-Kobe. That same day the Seishin Extension Line opened its first stage west of Myōdani to Gakuentoshi, and on 18 March 1987 the extension was completed through to Seishin-Chūō, so that the original Seishin Line now sat in the centre of a continuous Shin-Kobe–Seishin-Chūō route. Reciprocal through services with the Hokushin Express Electric Railway's Hokushin Line began at Shin-Kobe on 2 April 1988, extending journeys north toward Tanigami.
The line was caught up in the Great Hanshin earthquake of 17 January 1995, which damaged the subway and forced a shutdown. Recovery was staged: the Itayado–Seishin-Chūō portion, which includes the Seishin Line between Itayado and Myōdani, resumed limited running from the following day, 18 January, while the worst-hit central tunnels took far longer. Service across the whole route was restored on 16 February 1995 — among the earliest railways in the city to reopen, achieved by carrying out repairs overnight after a shortened operating day — with the three most heavily damaged stations, Sannomiya, Kamisawa and Shin-Nagata, reopening over the following weeks and normal operation returning on 21 July.
Today the Seishin Line is operated as an integral part of the Seishin-Yamate Line; from 1 March 2000 the Kobe Municipal Subway adopted "Seishin-Yamate Line" as the unified guidance name for the combined route. Successive generations of rolling stock have worked the line, from the original 1000-series through the 6000-series introduced from 16 February 2019, and on 5 January 2026 driver-only (one-man) operation began across the route.
