Oshi-Katsu Chronicle 2023: The WBC Title, YOASOBI's "Idol," Chanting Returns, and Twitter Becomes X
In 2023, Japan won the World Baseball Classic (WBC). In spring, the anime Oshi no Ko began airing, and its theme song, YOASOBI’s “Idol,” came to be heard in Japan and abroad.
At concerts, the infection-prevention limits on cheering aloud were eased, and shows where fans could call out from their seats returned. The year also saw Twitter renamed and a major talent agency restructured.
