Masashi Hioki, SASUKE Regular, Appointed Official Ambassador for 'Nin-JAPAN Cup' – Yaruki Switch Group's Sports Tournament for 10,000 Children Nationwide!
Yaruki Switch Group Co., Ltd. (Chuo-ku, Tokyo; Representative Director and President: Naoji Takahashi), a comprehensive educational service company, has appointed Masashi Hioki, a regular competitor on the popular TBS program "SASUKE," as the official ambassador to enliven the "Nin-JAPAN Cup." The cup is a major event where students of the "Ninja Nine®" sports class for toddlers and elementary school students compete to show the results of their daily lessons.
The "Nin-JAPAN Cup" is a passionate competition where children compete for the fastest time in a circuit format, based on the Ninja Drills they have practiced in their Ninja Nine lessons! A heated battle will unfold as children aim for the pinnacle of ninjas, conquering the top spot among 10,000 participants nationwide.
The "Nin-JAPAN Cup" has a very high affinity with "SASUKE" in terms of "challenging one's limits" and being a "one-shot match." This ambassador appointment was realized out of a strong desire to have Mr. Hioki—a SASUKE regular and part of the "dad generation" to Ninja Nine students—help elevate the children's challenges.

■ From "Nin-JAPAN Cup" Ambassador Masashi Hioki, to the Challengers of the Future!
Mr. Hioki, newly appointed as the ambassador, will appear as a guest at the national tournament held in August, witnessing the children's serious challenges up close.
Comment from Mr. Hioki
I felt it was very SASUKE-like to put everything on the line in a one-shot match. It's a wonderful place where the skills everyone has practiced come together to be tested. The actual performance carries a tension that can affect you mentally, which is exactly why it's important to be conscious of the real thing during practice. I'm cheering on everyone's challenge!
