Younha released the music video for “Sub Character” on her official YouTube channel on 5 March 2026. She has been recording under that single name since the mid-2000s, which makes her one of the longest-running solo acts on the Korean pop chart.

Younha built her career in Japan first

Younha debuted in Japan in 2004, as a teenager, before she had released anything at home. Her Japanese singles found an audience there and she came back to Korea in 2006 with a career already in progress — the reverse of the usual route, where a Korean act establishes itself domestically and then licenses that success abroad. Two decades on she still records in both markets. It is worth knowing because it explains why her back catalogue is split across two languages and two sets of release histories, something you will notice if you search for her older material.

About this release

“Sub Character” arrived as a music video on YOUNHA OFFICIAL, her own channel, published 5 March 2026 KST. The official description carries no credits beyond the title and a set of hashtags, including 혜성은_지지않는다 and 윤하_홀릭스 — the latter being the name of her fandom. No featured artist or producer is listed.

Watching from outside Korea

Artist-run channels like this one rarely add English subtitles, so turn on auto-translated captions if you want the description in your own language. Streaming availability outside Korea is generally good for Younha’s catalogue, though her Japanese releases sit under different listings.
