About SharkNinja × Grand Nikko Tokyo Daiba 'Ultimate Sleep Stay ~Sleep Tight in Suite~'

Interest in 'wellness tourism'—travel focused on physical and mental well-being—is growing worldwide. In particular, 'sleep tourism,' emphasizing 'quality of sleep,' is gaining attention both domestically and internationally. With rising summer temperatures and increasingly diverse lifestyles, more people face sleep challenges in daily life, increasing demand for 'comfortable sleep environments' even while traveling.

This plan features Shark's latest tower fan, the 'Shark® TURBOBLADE High-Power Tower Fan,' installed in each guest room. Its proprietary 'Air Blanket™' technology generates a gentle, enveloping airflow, creating a comfortable environment that avoids excessive cooling, even during summer nights.

Additionally, rooms are equipped with various sleep-supporting items, including the Airweave bed mattress and Mizuno's 'Deep Breathing Pillow -O2-', designed to simulate deep breathing even in sleeping positions.

Furthermore, limited-quantity items to support pre-sleep relaxation are available, including Kao's 'Megrizm Steam Eye Mask,' Tachibana Pharmaceutical's 'Suya Sleep Drink/Powder Type <Foods with Function Claims>,' NIVEA Kao's 'NIVEA Deep Moisture Night Protect,' and VENEX's 'Recovery Cross+'.

During the collaboration period, Shark fan products will also be deployed across various areas of the hotel. The outdoor poolside will feature the 'Shark® FlexBreeze Pro Mist Cordless Circulator Fan,' allowing guests to enjoy a cool and pleasant stay both indoors and outdoors. Additionally, a promotional campaign will be held, offering guests who stay during this period a chance to win Shark products through a lottery.
