Grand Prince Hotel Osaka Bay, an urban resort hotel in the Osaka Bay area, will open its 9th-floor rooftop garden pool for a limited summer season from Saturday, June 13 to Sunday, September 27, 2026. This year's theme, "City Break × Recharge," captures the spirit of a casual short trip that lets you escape the noise of daily life without going far (City Break), paired with a waterside experience that refreshes both mind and body through all five senses (Recharge).
Rooftop Garden Pool: "City Break × Recharge"
Day Pool: A Summer Resort for All Ages
The rooftop garden pool, perched on the 9th floor of the hotel, is a true summer oasis in the middle of the city. Along with a pool for adults, a dedicated children's pool is available, so families with young children can also enjoy the water with peace of mind.
Poolside food and drinks are plentiful, with lunch options including burgers, curry, and chilled udon noodles, as well as desserts like churros and pancakes.
Night Pool: A Glittering After-Dark Experience
When evening falls, the pool transforms into a vibrant, illuminated space that creates a distinctly different atmosphere from the daytime. It's designed as a luxurious retreat for adults, and photo-friendly float rentals are available to make the most of the illuminated setting.

A Special Peroni Beer Presentation
Back by popular demand from last year, the premium Italian beer Peroni is available poolside again this summer. When you order a Peroni Nastro Azzurro, the beer is poured into an original glass and spritzed with a citrus-scented fragrance (profumo) for a special sensory presentation that enhances every sip.
A Variety of Plans to Choose From
Several plans are on offer to match different preferences: a combined pool admission and hotel buffet restaurant ticket, a hotel stay package with day pool access, and a plan that includes a parfait at the Sky Bar 100 meters above ground after the night pool.
The image below shows the Korean buffet "K-Food Holic Vol.2" running from June. The buffet combo ticket is expected to go on sale from mid-June.
