2. Who is Mari Hoshino's daughter, Fuuka?

Mari Hoshino has a daughter named Fuka. In September 2024, Hoshino announced that Fuka has a rare disease called congenital myopathy. It has been reported that Fuka uses an electric wheelchair to get through her days.

In the 2025 "24-Hour Television" program, Fuuka took on a challenge where she and two friends from kindergarten went out into the city in electric wheelchairs. Her mother, Mari Hoshino, watched over them from the sidelines.

This year, the roles are reversed. The mother who watched her daughter's challenge will now run herself. Knowing this progression reveals how deeply this charity marathon is intertwined with a family story.

3. Congenital Myopathy and a Family's 10-Year Life

Congenital myopathy is a disease characterized by weakness of muscles and delayed motor development from birth. In the interview with Bunshun Online, Fuuka talks about how she came to realize she had the disease and the time her family has spent coping with it.

Not only did Mari Hoshino publicly announce her daughter's illness, but she and her husband also obtained qualifications as social workers. Her commitment to not just disclosing the diagnosis but also to continuously thinking about how to create a society where children with disabilities and illnesses can live more easily is what led to this current challenge.

4. The wish behind "Why do I run?"

Mari Hoshino, having spent 10 years with her daughter, has come to wish for a world where all children are not separated and can choose their own place in the world. She says she hopes that running this time will be an opportunity for people to think about a kinder world.

These words aren't just empty platitudes. Electric wheelchairs, ventilators, school, friendships, ease of going out—because she and her family have witnessed these small obstacles in everyday life, Mari Hoshino's "reason for running" carries significant weight.

The 24-Hour Television marathon receives significant attention every year, but this year, in addition to the distance and the finish line, we should also focus on what Mari Hoshino is trying to convey.

5. Does Chanmina have a cheering song?

Chanmina will serve as a special supporter for "24-Hour Television 49" in 2026. Her name is also listed in the program's official cast list.

On June 22nd, an article was published suggesting that a special performance, such as a support song by Chanmina, was being considered for Mari Hoshino's 24-hour marathon. However, this has not been officially confirmed by the program. At this point, it is natural to treat it as "something that might happen."
