Behind the Design: The 24-Hour Television 2021 Charity T-Shirt Collection
Every year, Nippon TV’s 24-Hour Television brings people together through inspiring stories, charitable giving, and its iconic official Charity T-Shirt ("Charit-Shirt"). The 2021 collection (the 44th annual event) stands out as a unique fusion of J-Pop culture, mascot design expertise, and a powerful message of hope.
Let's dive into the story behind the design, the creative minds involved, and the full color lineup that fans and collectors love.
The Design Collaboration: King & Prince x Kumamon Creator
The 2021 Charity T-shirt was brought to life through a special collaboration between two creative powerhouses:
- Kaito Takahashi (高橋海人): Member of King & Prince (who served as the main personalities for 24-Hour Television 44) and a talented manga artist and illustrator.
- Manabu Mizuno (水野学): Acclaimed creative director, founder of good design company, and the visionary behind Japan’s famous mascot, Kumamon.
Together, they crafted a design that balances playful Japanese character aesthetic with a timeless vintage graphic tee feel.

Meet "Omo-Wolf" (おもウルフ)
At the center of the graphic is a charismatic wolf character named Omo-Wolf. The character's name is a double wordplay:
- Omoi (想い): Representing thoughts, warmth, and care for others.
- Wolf (ウルフ): Wolves naturally thrive within a pack, symbolizing community support, togetherness, and interconnectivity.
Adorned with a bright yellow bandana, Omo-Wolf is depicted howling toward the sky—sending thoughts of unity and encouragement across the world under the official theme slogan: "Believing The World Will Change".

- Soft Pink: A gentle, warm hue symbolizing compassion and care.
- Natural Khaki/Beige: An earthy, modern tone for versatile everyday streetwear styling.
