December 10 on what J-Pop has that the UK doesn't

From Asia to the World — A New Era of Sound アジアのシーンを牽引するアーティストたちとの対話を通して、"アジアミュージック"という未定義のカルチャーに輪郭を与えていく。 ■ DECEMBER 10　/ ディセンバー・テン Seven strangers, one Netflix series — and a band name that is also their birthday. December 10 is an English–Irish UK boy band born on the Netflix documentary series "Simon Cowell: The Next Act," which followed Cowell's search for a new group and premiered on 10 December 2025 — the date that became their name. Cowell set out to sign five and kept all seven: Cruz, Danny, Hendrik, John, Josh, Nicolas and Seán. A week before the audition, none of them was anywhere near a stage. Seán was on a remote island off the Irish coast with no phone signal, speaking Irish; John had just turned 16 and started was about to start his first job at McDonald's; Cruz was playing pre-season football and pouring drinks at a Hilton bar; another was working the grill at Nando's. They play 14 instruments between them, and the first year has been fast: the debut single "Run My Way" in January 2026, then "Angel," "Infinity (123)" and "Us Against The World"; a debut EP, "On Your Side," that entered the UK Albums Chart at No. 5; a Wembley Stadium crowd of 90,000. Japan came early: Summer Sonic SUMMER SONIC 2026 in Osaka and Tokyo, then a first solo show in the country at Spotify O-EAST in Shibuya. They sat down with YUGEN the day after Summer Sonic SUMMER SONIC, six of them (Danny is taking a break time out), still a little stunned by Japanese crowds that clap in perfect sync, and by a karaoke machine that played "Run My Way" ten times in a row. それぞれ別の道を歩んできた7人と、1本のNetflixシリーズ。そして「誕生日」が、そのままバンド名になった。 イングランド＝アイルランド出身イギリス発の7人組ボーイバンド。サイモン・コーウェルが新しいグループを探す過程を追ったNetflixのドキュメンタリーシリーズ『サイモン・コーウェル: Who's The Next?』（原題『Simon Cowell: The Next Act』）から誕生し、シリーズの配信日である2025年12月10日がそのままグループ名になった。5人を選ぶつもりだったコーウェルは、最終候補の7人全員——Cruz、Danny、Hendrik、John、Josh、Nicolas、Seán——を残した。オーディションの1週間前、彼らはステージとは無縁の場所にいた。Seánは電波の届かないアイルランドの離島でアイルランド語を学び、Johnは16歳になったばかりでマクドナルドの初バイトを始めたところ。Cruzはサッカーのプレシーズンをこなしながらヒルトンのバーで酒をつくり、もうひとりはNando'sの鉄板の前にいた。7人で14の楽器を弾く。最初の1年は速かった。2026年1月のデビューシングル「Run My Way」から「Angel」「Infinity (123)」「Us Against The World」、全英アルバムチャート初登場5位のデビューEP『On Your Side』、ウェンブリー・スタジアムの9万人。日本との出会いも早かった。8月のサマーソニック2026（大阪・東京）、その直後には渋谷 Spotify O-EAST で日本初の単独公演。YUGENの収録はサマソニの翌日。休止中のDannyを除く6人は、手拍子まで揃う日本の客席と、「Run My Way」を10回リピートし続けたカラオケの機械に、まだ少し呆然としていた。 ■ FOLLOW DECEMBER 10 Official Website: https://www.december10.com/ Instagram: https://www.instagram.com/december10/ X: https://x.com/D10Band X (Japan): https://x.com/December10JP TikTok: https://www.tiktok.com/@december10 YouTube: https://www.youtube.com/@December10Band Streaming（Debut EP「On Your Side」）: https://december10.lnk.to/OnYourSideEP Universal Music Japan: https://www.universal-music.co.jp/december10/ Netflix「Simon Cowell: The Next Act」: https://www.netflix.com/title/81743409 ■ YUGEN OFFICIAL Web Site: http://ygen.net/ ■ CHAPTERS 00:00 Intro 01:43 Welcome to the YUGEN Podcast 02:51 From five members to seven, and working with Simon Cowell 05:10 How the name December 10 stuck 06:20 No phones in Miami 07:23 One week before the audition 13:08 The Asian artists they love, and their favorite anime 15:21 Seven songs mashed into one 18:00 From choirs to tap dance, where each of them started 22:46 Who's who in December 10 25:02 What sets them apart from the boy bands before them 26:17 Japanese crowds and SUMMER SONIC 30:08 Meeting XG, and Asian music going global 33:42 The most Japan thing: karaoke and conveyor belt sushi 36:08 One song for Japan, and who should come next CREDITS YUGEN Production Committee ― MC: Isaac Y.
