Anime is Japan's music export engine: what 'IRIS OUT' and Ado teach artists about sync

The biggest Japanese song of 2026 so far started as an anime film theme. On 5 Jun 2026 Billboard JAPAN named Kenshi Yonezu's "IRIS OUT", written for Chainsaw Man – The Movie: Reze Arc, the No. 1 on its first-half Hot 100. The same announcement notes that the song reached No. 5 on the US Billboard Global 200 dated 4 Oct 2025, the highest position yet for a Japanese-language song, and credits anime's popularity for helping it become a hit at home and abroad.

That fits a pattern the data firm Luminate has been tracking, and a government estimate of what Japanese music actually earns abroad. Read together, they say a lot about how sync placements (licensing music to film, TV, games and ads) turn into careers, and that holds well beyond Japan.

How big was "IRIS OUT"?

According to the announcement, "IRIS OUT" reached 100 million streams in four weeks, the fastest in Billboard JAPAN history. It also topped Global Japan Songs Excl. Japan, a chart Luminate compiles from streams and downloads in more than 200 countries and regions outside Japan. The first-half charts covered 24 Nov 2025 to 24 May 2026; the overseas charts ran 21 Nov to 21 May (OTOTOY has the same dates and details).

It wasn't the only anime song near the top. Mrs. GREEN APPLE, the No. 1 act on the Artist 100 for a third year running, was represented by "lulu.", the opening theme for the second season of Frieren: Beyond Journey's End. Billboard JAPAN even runs a separate Hot Animation chart for tie-in songs, as THE FIRST TIMES notes in its write-up.

Why does anime do the exporting?

Luminate's media analyst Robert Steiner put it plainly in March. Japan is the world's second-largest recorded music market by IFPI's count, yet J-pop has stayed focused on its home market, and anime openings are often how its artists first break through abroad. His examples:

• YOASOBI, "Idol". The opening theme of Oshi no Ko, released in April 2023, had 3.9 billion lifetime global on-demand streams (audio plus video) by 12 Feb 2026. It became the fastest Japanese song to reach diamond certification from the Recording Industry Association of Japan, and its No. 7 peak on the Global 200 was the record for a Japanese artist until "IRIS OUT" beat it in late 2025.
• Ado. Her listening first spiked abroad after her music appeared in One Piece and Spy x Family in 2022 and 2023. On her 2025 Hibana world tour she sold out Los Angeles' Crypto.com Arena, the first Japanese artist to do so, and played London's O2 Arena. Luminate says her daily on-demand streams outside Japan now slightly exceed those at home, and with 212.1 million on-demand streams she was the most-streamed Japan-based artist in the US in 2025.

The Ado example matters most to us. The anime placement wasn't the career. It was the first way in. Luminate credits her persona, her steady output and her online following for the growth that came after.

What does Japan actually earn from music abroad?

Until this year nobody had a good answer. On 30 Apr 2026 Japan's Ministry of Economy, Trade and Industry (METI) published a report on a long-noted gap: the industry had no shared overseas data usable as statistics. It came with an estimate for 2024. METI counts two things: overseas income, the money Japanese people and companies receive from abroad, and overseas sales, what is spent abroad on Japanese music.

Two things stand out in our reading of the table. First, streaming is about three-fifths of the income METI can trace from abroad, excluding visitors, while the rights line, which lumps royalties and sync fees together, is under a sixth of it. Second, overseas live sales are more than ten times overseas live income. That suggests most of what fans abroad spend on concerts stays with local promoters, venues and ticketing rather than coming back to Japan. METI doesn't break any of this down by anime, so how much of the streaming line anime drives isn't measured.

What we think

Anime is Japan's best discovery channel, and the METI table shows where the money from that discovery ends up: in streams and tickets, much later, not in the placement fee. Four lessons apply wherever you make music.

A tie-in is marketing, not income. If sync fees and royalties together come to ¥6.87bn against ¥26.53bn from streaming, the value of a placement is the listeners it brings to everything else you've released. Judge a sync offer on how visible it is (opening credits, a trailer, a game's title screen) as much as on the fee.

Write for the picture. "IRIS OUT" was written for the film, not licensed from a back catalogue. A song made to fit a story is more likely to become that story's sound, and that is what sends a viewer to look it up. For an independent artist the equivalents are indie games, web series, regional cinema and creators' channels, which are much easier to reach than a major anime.

Plan for the second step. Ado turned anime spikes into arena shows abroad within about three years. The METI gap between live sales and live income is a warning, though: touring abroad grows your reach faster than your bank balance unless you control the deals.

Own enough to collect. Streaming income only reaches the artist who holds a share of the master or publishing, and is registered to collect it in every territory. If you're pitching for placements, sort your splits, metadata and collecting-society registrations first. A placement that goes viral overseas pays far less if the money can't find you.

The honest limit is access. Anime themes go to a small number of artists, mostly through labels and production companies, so the copyable part for most musicians is the pattern rather than the placement itself.
