Getting to Know Grand Cube Osaka
Welcome, and congratulations on your upcoming business meeting or conference in Osaka. Grand Cube Osaka (officially the Osaka International Convention Center) opened in April 2000 and has become the flagship convention facility of Osaka’s Nakanoshima district, hosting everything from international conferences and academic conventions to exhibitions and ceremonies.
The venue sits on Nakanoshima, an island framed by the Dojima River and the Tosabori River, and is served so directly by public transit that the local Keihan Nakanoshima Line station carries the venue’s own name. The adjacent Rihga Royal Hotel Osaka connects to the venue via a first-floor covered passage, making it easy to move between your accommodation and the conference floor.
This guide covers how to get to Grand Cube Osaka, how to choose a nearby hotel, where to eat, and practical points worth knowing before your visit. It also covers the venue’s officially announced large-scale renovation closure schedule beginning in 2029 — worth checking if you’re planning an event further out.

The Keihan Nakanoshima Line’s Nakanoshima Station carries the venue’s name for a reason — Exit 2 leads directly to Grand Cube Osaka. From the other stations, plan for roughly a 10–15 minute walk. Nakanoshima is the closest station, but Watanabebashi Station on the same line is also within about an 11-minute walk, and you can walk west along the Dojima River from there.
If you’re coming from the Umeda area (including Nishi-Umeda Station on the Osaka Metro Yotsubashi Line), take the Midosuji Line from Umeda to Yodoyabashi, then transfer to the Keihan Nakanoshima Line and get off at Nakanoshima Station (Exit 2, immediate). A free Rihga Royal Hotel shuttle bus also runs from JR Osaka Station (Sakurabashi exit, approx. 15 min). Nishi-Umeda Station itself is about a 20-minute walk away, so transferring or taking the shuttle bus is more comfortable.

One point in particular deserves attention: the large-scale renovation closure scheduled from 2029. On March 30, 2026, Grand Cube Osaka officially announced a notice titled “Closure for Large-Scale Renovation Work,” stating that with the building marking its 25th anniversary, renovation work will be carried out to keep the facility comfortable for continued use. The confirmed schedule is a full-building closure from June 2029 to March 2030, and a Main Hall closure from May 2029 to May 2031 (which includes the full-building closure period). During the period when only the Main Hall is closed, the Event Hall, Special Conference Room, individual meeting rooms, the basement parking garage, and in-house restaurants remain available as usual, and a 10% discount on venue fees applies when using those non-affected facilities. The official website also notes that “the construction and closure schedule may change depending on the progress of design work going forward,” and as of 2026, the venue remains in normal operation for now. Bookings for the post-closure period will continue to be accepted by email (info@gco.co.jp) or phone (06-4803-5585). (Official announcement: Closure for Large-Scale Renovation Work, Japanese only)

The nearest station, Keihan Nakanoshima Line’s “Nakanoshima (Osaka International Convention Center)” Station, carries the venue’s own name — Exit 2 leads directly to Grand Cube Osaka. Even with a lot of luggage, you won’t need to worry about getting lost.
☔ Via Rihga Royal Hotel Stays Drier on Rainy Days
Grand Cube Osaka connects to Rihga Royal Hotel Osaka via a first-floor covered passage, and the hotel in turn connects to Nakanoshima Station via an underground passage. This route can help you stay drier on rainy days, though neither official website spells out whether every segment of the route is fully covered — check with each facility for the latest details.
🏪 No Shop or ATM On-Site — Check Nearby Convenience Stores in Advance
According to the official FAQ, the venue has no in-house shop or ATM. If you’re attending a long event, it’s worth locating a nearby convenience store beforehand.
🌸 Nakanoshima Sits Between Two Rivers and Is Known for Cherry Blossoms
Grand Cube Osaka sits on Nakanoshima, an island between the Dojima River and the Tosabori River. The adjoining Nakanoshima Park is planted with roughly 100 Somei Yoshino cherry trees. If visiting during cherry blossom season, build extra time into your schedule for larger crowds in the area.
