With the concept of "Enjoy golf seriously while smiling,"
it aims to be "an adult social gathering" where people can enjoy themselves seriously with friends, distinct from business entertainment or simple competitions.
Furthermore, the high level of competitiveness is one of RYTHM CUP's attractions.

■ Reason for Rin's Sponsorship of the Tournament
This tournament naturally becomes a place where participants confront golfer-specific condition challenges such as post-round fatigue and UV damage.
"Rin," a beauty brand developed by Cantik LLC, resonates with the desire to "support everyone who enjoys golf to play in better condition," and supports this tournament from the perspective of inner condition care.
The supplement "Rin NMN White PLUS" is a product that combines NMN and oral UV care ingredients. It is gaining attention as an "effective inner care" product that supports the health and condition maintenance of adults who enjoy golf, allowing users to feel the difference in their performance and skin condition the next day.
Furthermore, the champion sisters who organize this tournament are regular visitors to our salon and are actual users of "Rin NMN White PLUS."
The fact that it is incorporated into daily life for condition care while enjoying golf is also one of the backgrounds for this sponsorship.
