Forming a new north-south line with the
opening of the Naniwasuji Line

Obtaining the urban planning project approval for the
“Naniwasuji Line project” and preparing for construction

Regarding the Naniwasuji Line project currently scheduled for a 2031 opening, project organizer Kansai Rapid Railway Co., Ltd. obtained urban planning project approvals for the railway segment in August 2020 and the road segment in January 2021. In October 2021, construction began on the Nakanoshima Station (tentative name) and Nishi-Honmachi Station (tentative name) sections, and preparatory work has also begun on the Nankai Shin-Namba Station section and the branch tunnel section, as we steadily advance our efforts toward the opening.
The consigned design for the new elevated bridge we have taken on for the north side of the Shin-Imamiya Station intersection, and the survey of the existing elevated bridge needed to install new railway switches, are also going according to plan. Going forward, we will continue to work steadily on these projects while closely collaborating with the national government, local municipalities, and associates.


Major benefits expected from the Naniwasuji Line

    National core route of Shin-Osaka and central Osaka will be directly connected to other areas such as southern Osaka.

    The Umekita area will become more accessible, and community development in the Nakanoshima area will improve.

    There will be better accessibility to Kansai International Airport.

    It will generate interactions between tourism spots across a wider region.

    There will be better accessibility to the Namba area.
