TENTIAL Co., Ltd. (Location: Shinagawa-ku, Tokyo, Representative Director and CEO: Yutaro Nakanishi, hereinafter 'TENTIAL'), which develops the conditioning brand 'TENTIAL' aiming to realize a society positive about health, will hold 'SPRING CONDITIONING' for a limited period from Wednesday, April 1st to Tuesday, April 14th, as an opportunity to review one's condition and tune up the body.
Since its founding in 2018, TENTIAL has operated with the mission 'Create a health-positive society and draw out human potential,' deploying conditioning*1 products including the recovery wear 'BAKUNE'. Spring, marking the start of a new fiscal year, is a season where the body easily bears burdens due to disruptions in daily rhythms caused by temperature fluctuations and environmental changes. On the other hand, many people feel a hurdle in adopting new habits amidst their busy daily lives. Therefore, TENTIAL proposes an approach of 'replacing' everyday items with those designed for conditioning. Through products easily incorporated into daily life, such as recovery wear 'BAKUNE', clothing, and bedding, we support effortless conditioning.
In the 'SPRING CONDITIONING' campaign, which aims to help people review their spring conditioning, those who purchase eligible products totaling 30,000 yen (tax included) or more will receive special novelties supporting conditioning, such as a travel pouch that allows easy carrying of BAKUNE and can be washed whole as a laundry net, or a mesh tote useful for the gym and sauna scenes. Furthermore, 30 people selected by lottery from those who purchase the SPRING CONDITIONING limited set items will be presented with a 'Hoshino Resorts Accommodation Gift Voucher' worth 50,000 yen.
Adjusting one's condition is an important element that supports daily performance. Precisely because spring is a time when one's condition tends to falter, we will closely support everyone's daily conditioning.
*1 At TENTIAL, conditioning is defined as 'tuning all factors related to physical condition into a good state in order to improve life performance.'

Spring is balmy, sleep is shallow, and the body feels heavy—Spring is a season with pollen, new interpersonal relationships, and changes in workplace roles...
