Mitsui Fudosan and Kanden Real Estate to build a 12,500-seat arena on Kubota's 130-year Namba site
Kubota is handing its 130-year-old Namba headquarters site to an arena, a hotel and shops, three months after moving its own operations to Grand Green Osaka.
Mitsui Fudosan and Kanden Real Estate Development said on August 5 they have signed a basic agreement with Kubota Corporation to redevelop the manufacturer's former Osaka headquarters site into an arena seating roughly 12,500, plus a hotel and commercial space, the companies announced.
The site, in Naniwa Ward's Shikimatsu-Higashi district near Namba Station, covers about 24,000 square metres and served as Kubota's head office for around 130 years. The company vacated it on May 1, 2026, relocating to Grand Green Osaka's Park Tower after citing the ageing of its former facilities, according to the companies' own announcements.
Under the agreement, Mitsui Fudosan will develop and operate the arena, tentatively named "Kubota LaLa arena," while Kanden Real Estate Development takes on the hotel and the commercial floors; the wider site will carry the working name "Kubota field." Multiple train stations lie six to twelve minutes' walk away, the companies said.
The companies are targeting an opening in 2032 or later; neither the investment amount, the floor area nor the hotel's room count has been disclosed, and this week's announcement covers only a basic agreement, not a construction start.
A retail bet as much as a sports one
An arena's economics rarely rest on ticket nights alone. floortok's read is that the real value here is the recurring footfall a 12,500-seat venue feeds into the hotel and shops built alongside it on the roughly 350-plus days a year nothing is on stage. Building in Namba — already one of Osaka's densest shopping and dining districts — rather than on a greenfield site is a bet that an arena crowd converts more easily where retail habit already exists than where it has to be built from nothing.
What the agreement does confirm is Kubota's own choice: rather than sell a rare, fully-cleared 24,000 sqm plot in central Osaka for straightforward office or residential towers, it opted for a multi-decade entertainment-and-hospitality partnership — a bet on the site's footfall value outlasting a simpler sale. With six years or more before doors open, the numbers that will matter — the investment size, the hotel operator, the arena's booking calendar — are still to come.
