Hotel New Otani Makuhari
Outdoor Pool 'Shell Pool'
View Details
Hotel New Otani Makuhari will operate its outdoor pool 'Shell Pool' for a limited time from Saturday, July 18, to Tuesday, September 22 (holiday), 2026. Despite its highly accessible location just about 30 minutes from central Tokyo, you can spend an extraordinary and healing summer moment at this open-air pool reminiscent of a tropical overseas resort.
* Advance reservations will begin on Monday, June 1 at 10:00.
An Extraordinary Space Woven with Lush Greenery and an Open Blue Sky, Just Like a Tropical Resort
Last weekend, the Japanese archipelago was covered by unseasonably warm air, and central Tokyo recorded its first summer day of the year (25.3°C) on Saturday, April 11. The temperature rose further to 26.2°C the next day, Sunday, April 12, marking two consecutive summer days. As full-fledged summer approaches, Hotel New Otani Makuhari's summer synonym, the outdoor pool 'Shell Pool', will open for a limited summer season. The elegant shell-shaped pool, lush trees such as palm trees swaying in the wind—step inside, and you are transported to a tropical overseas resort. The perfect location, fitting to be called the closest 'healing resort pool' from central Tokyo, welcomes you.
Day Pool Now Operates Continuously from Morning to Evening! Flexible 'Short Plan' Also Debuts
The two-part system for the day pool, introduced in 2020, has been abolished from this summer, and it has been decided to operate continuously from 9:00 to 17:00. You can relax and enjoy the open day pool at your own pace without worrying about the time.
Furthermore, in response to requests such as 'I want to experience a little bit of a resort feeling between schedules' and 'I want to easily enjoy the pool in a short time', a 'Short Plan' that allows you to use the pool for 2.5 hours from your preferred timing until the end of the day pool will debut this year! It is the first smart plan by Hotel New Otani that allows you to use it flexibly according to your schedule.
This Year's Theme is 'PINK & GOLD'. A Summer Night Resort Experience Surrounded by Magical Light
'I want to fully enjoy the summer mood without worrying about the sun!'. Hotel New Otani Makuhari's night pool makes such dreams come true. This year's theme is 'PINK & GOLD', multiplying exciting 'pink' and sparkling 'gold'. Every night during the period, the entire pool is lit up with pink and gold lights, and the magically illuminated space is photogenic from any angle. Please fully enjoy the adult summer night woven by the sparkling water surface and vivid lights.
Two New Special Plans for Students & Families Debut at This Year's Night Pool!
The 'Student Discount Plan', which was highly popular when sold exclusively last September, will appear exclusively for July this year. To help you start the best summer vacation as a reward for your hard work in the first semester, it will be sold from the opening day of the night pool (July 18). Exclusively for junior high school to university/vocational school students, by presenting a student ID upon entry, you can enter for ¥3,000, less than half the regular maximum price of ¥6,500 per person. Furthermore, groups of 4 or more students will receive one non-alcoholic drink per person! The hotel fully supports the 'best summer vacation start dash' for students.
In addition, responding to the passionate requests from families with children over the years asking to 'use the night pool with children', we have finally lifted the ban on children entering the night pool this summer and prepared a 'Family Night Pool Plan' exclusively for staying guests. Please enjoy the sparkling and magical atmosphere of the night pool with your whole family.
* When using the 'Family Night Pool Plan', the use of the night pool is limited until 19:30.
