TheSakurajima Line (桜島線,Sakurajima-sen) is a railway line inOsaka, Japan, operated byWest Japan Railway Company (JR West) connectingNishikujō Station toSakurajima Station. It is also referred to as theJR Yumesaki Line (JRゆめ咲線). The entire line is withinKonohana-ku, Osaka, and connects theOsaka Loop Line toUniversal Studios Japan (USJ).

The nickname "Yumesaki Line" was determined in a public poll upon the opening of USJ and the Universal City station. While it was not the first choice, its pleasant sound together with the vision of the area around the Sakurajima Line and USJ being a place where Osaka's dreams were continuing to be born made it the selected choice.

The line is used primarily by a mix of factory workers and tourists. There is also freight traffic operating between Suita and Ajikawaguchi.

No.	Station	Japanese	Distance (km)	Transfers

JR-P16	Universal City	ユニバーサルシティ	3.2
JR-P17	Sakurajima	桜島	4.1

In addition to trains that operate only on the Sakurajima Line itself, there are also direct services fromTennōji,Kyōbashi, andOsaka stations that alternate during non-peak times. Also, during peak travel seasons, seasonal trains (such as theUniversal Express limited express service) will run through to/from theHokuriku 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. In 2025 during the 2025 Expo there will be a temporary Train called the Expo liner from/to Shin Ōsaka and Sakurajima stopping at Ōsaka,Universal City, and Sakurajima. These trains operate once an hour^[1]

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.

WhileUniversal Express trains make their final stop at Universal City, there are nopoints 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 theOsaka 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 theKatsuki Line on April 1, 1985, until the beginning of service on theMiyazaki 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 theShinminato Line inToyama 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.

• 103 series (6-and 8-car formation) (from 1969 to 2017)
• 201 series (8-car formation) (from 2005 to 2019)

Because the Sakurajima Line is the main access route for USJ, 103 series and 201 series 8-car trains are decorated with USJ advertisements, although previously 103 series 6-car trains also featured USJ-relatedwrap advertising.

On September 10, 2009, the then Governor of Osaka PrefectureTōru Hashimoto announced that he was examining a 4 km extension of the Sakurajima Line fromSakurajima toTrade Center-mae on theNankō Port Town Line (New Tram).^[3] This was to improve access to theWorld Trade Center (WTC) inSuminoe-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.
