QUARTZ SHINSAIBASHI's new restaurant floor opens with nine tenants, three of them debuts
The dining floor completes the Shinsaibashi tower's public-facing programme, pairing a nationwide crab-specialist debut with two Kansai-first concepts inside Osaka's newest mixed-use address.
The fifth-floor restaurant zone at QUARTZ SHINSAIBASHI, a mixed-use tower in Osaka's Shinsaibashi district, opened on 16 July with nine dining tenants, according to the facility's operators.
The complex is developed by Hulic, the Shinsaibashi Development special-purpose company (a joint venture between L Catterton Real Estate and J. Front Urban Development), Takenaka Corporation and JR West Real Estate Development. QUARTZ SHINSAIBASHI itself rises 28 storeys above ground and two below, reaching roughly 132 metres with about 46,227 square metres of floor area; construction was completed in March 2026.
Three of the nine restaurants carry debut billing: a Chinese/xiaolongbao concept from Paradise Dynasty (trading locally as Rakuten Kocho) is opening its first Osaka location, crab specialist Kaniju is opening its first location anywhere in the country, and shabu-shabu and sukiyaki restaurant Kobai is opening its first Kansai location — all three also described by the operators as new store formats. Tonkatsu chain Haoju Saboten is opening its first Kansai location as well. The remaining tenants — Mercer Brunch Shinsaibashi, eel restaurant Sumiyaki Unafuji, izakaya Yama, yakiniku chain Jojoen Yugentei and Sushi Amato Shinsaibashi — round out the floor.
A dining floor built around debuts rather than familiar chains is a Product bet as much as a leasing one — it gives QUARTZ SHINSAIBASHI a reason for Osaka diners to visit that a floor of already-familiar names would not, at the cost of unproven demand for at least three of the nine tenants. It also completes the building's vertical mix, adding a food-and-beverage layer to a Shinsaibashi tower that already combines a basement food hall with hotel and office floors above.
