Hattie Stewart x Naomi Watanabe: The Iconic 2018 24-Hour Television Charity T-Shirt

In Japan, NTV’s 24-Hour Television ("Love Saves the Earth") is widely celebrated as one of the biggest live television events of the summer. For over four decades, this annual charity telethon has raised funds for welfare initiatives, disaster relief efforts, and environmental protection across the globe. Over the years, the program has collaborated with top artists and fashion icons—including Takashi Murakami, Yayoi Kusama, NIGO (A Bathing Ape), and Arashi—to produce limited-edition charity T-shirts.

The 2018 edition marked a major milestone in the event’s history: for the very first time, the official charity T-shirt was released featuring two distinct side-by-side graphic designs on a single garment.

The Creative Powerhouse Behind 2018’s Design

The 2018 charity T-shirt was created by London-based illustrator Hattie Stewart, world-renowned for her vibrant "doodlebombing" pop-art style. Known for her playful characters and bold lines, Stewart teamed up with Japanese comedian and fashion icon Naomi Watanabe (who served as Special Supporter) .

Dual-Face Design Concept: Front & Back Synergy

The 2018 T-shirt broke traditional telethon merchandise molds by introducing a dual-sided graphic theme:

  • Front Graphic: Features a heart character adorned with big, expressive eyes and a cheeky smile, symbolizing love and warmth.
  • Back Graphic: Showcases a playful star-encircled portrait character.

Available in a spectrum of vibrant colors—including Yellow, Pink, Black, White, and Purple—the T-shirts catered to diverse tastes while retaining a unified message of hope and solidarity.

Preserving Your Pre-Owned Art Apparel

Whenever we add a vintage screen-printed piece to our personal rotation, we follow strict care steps to keep the cotton fibers and graphics in museum condition:

  1. Wash inside out on a cold, delicate cycle to prevent print friction.
  2. Line dry in the shade to protect the vibrant yellow fabric from sun fading.
  3. Never iron directly over graphics or screen prints.
