What happened

Snow Man is a Japanese idol group (a pop act whose members are marketed individually to fans), and several of them host a regular radio show called Sunomanma on the broadcaster Bunka Hoso. On June 4, 2026, the show ran a promotional 'Special Week' episode hosted by two members, Iwamoto Hikaru and Abe Ryohei. The show's official account asked listeners to tune in live and post under its hashtag during the broadcast, which is how the topic climbed Japan's trends.

Why it is trending now

Two things stacked together. First, 'Special Week' is a periodic promotional push that fans treat as a must-listen event. Second, a baseball game scheduled before the slot ran long, so the show's team warned the start could slip — and it eventually began around 9:11 p.m. instead of the planned 9 p.m. The delay updates themselves drew attention, keeping fans refreshing the hashtag while they waited.

How fans reacted

Iwamoto and Abe were both born in 1993, and fans celebrated the 'same-grade' pairing the moment the two opened the show by riffing on being classmates. Listeners clipped favorite lines — including talk about Iwamoto's long-distance run — and shared them in real time. The episode also aired on radiko (Japan's radio streaming service), making it easy to follow along live.

What to watch next:

Sunomanma rotates its hosts each week, so attention will likely shift to which member combination appears in upcoming episodes. Past lineups have included other member pairings, and any full-group reunion episodes tend to spike interest sharply.
