Sakurajima Line

In addition to trains that operate only on the Sakurajima Line itself, there are also direct services from Tennōji, Kyōbashi, and Osaka stations that alternate during non-peak times. Also, during peak travel seasons, seasonal trains (such as the Universal Express limited express service) will run through to/from the Hokuriku Main Line. However, as the number of visitors to USJ has been on the decline in recent years, such special trains are now only rarely operated.

As a contingency in the event of a service disruption, the line has bi-directional signalling, meaning trains can operate in either direction on either line between Nishikujō and Universal City.

While Universal Express trains make their final stop at Universal City, there are no points for them to change directions at that station. Such trains proceed to Sakurajima and change directions there.

Originally the Nishikujō – Sakurajima section was not a separate line, but part of the Nishinari Line, which was operated by the private Nishinari Railway and featured a movable bridge over the Hokkō Canal on the Ajikawaguchi to Sakurajima section. A portion of the Nishinari Line became a part of the Osaka Loop Line when it was completed in 1961, with the rest becoming the Sakurajima Line. The line served as a commuter route for workers in factories along the line as well as for freight, with limited off-peak patronage. This continued until the construction of USJ, which resulted in tourists being the main users of the line.

From the end of operations on the Katsuki Line on April 1, 1985, until the beginning of service on the Miyazaki Kūkō Line on July 18, 1996, the Sakurajima Line was the shortest passenger line among the JR Group companies. (Including freight lines, the shortest at the time was the Shinminato Line in Toyama Prefecture.)

Sakurajima Station was relocated on April 1, 1999, the lift-bridge on the former line being unused since the canal was filled in the 1990s.

When service began at Universal City Station, there were requests by local residents and business owners for a new station ("Haruhinode Station") between Nishikujō and Ajikawaguchi stations. However, not enough demand was forecast and the requests were not met.

On September 10, 2009, the then Governor of Osaka Prefecture Tōru Hashimoto announced that he was examining a 4 km extension of the Sakurajima Line from Sakurajima to Trade Center-mae on the Nankō Port Town Line (New Tram).[2] This was to improve access to the World Trade Center (WTC) in Suminoe-ku, to which the governor considered moving the prefectural government offices. Traveling from Osaka Station to the WTC requires at least 30 minutes, and this inconvenience is considered a major obstacle to any move. Although the prefecture is willing to foot at least part of the estimated construction cost of 100 billion yen, there has been no discussion yet of the effect on travel patterns with existing transit agencies/companies.

Of the estimated 4 km length of the extension, approximately 3 km would be underground. Travel times between Osaka and the WTC are expected to drop to 20 minutes if completed.
