This year has been absolutely massive for anime theme songs, and superstar Kenshi Yonezu has been at the forefront, dropping tracks for "Mobile Suit Gundam GQuuuuuuX," "The Gold Winner," and "Chainsaw Man Reze Arc." It's been a year where he's truly showcased his boundless creative genius.
Kenshi Yonezu's theme song for "Chainsaw Man Reze Arc," "IRIS OUT," has been absolutely tearing up the charts lately, not just smashing records in Japan but also achieving unprecedented global success. It recently hit a new milestone, breaking his own "Lemon" record by holding the #1 spot on Billboard JAPAN for an incredible 8 consecutive weeks.
According to the latest Billboard JAPAN "JAPAN Hot 100" chart (dated November 12, 2025), "IRIS OUT" snagged its eighth consecutive week at #1. This officially surpasses his previous magnum opus, "Lemon," which held the top spot for 7 weeks, making "IRIS OUT" Yonezu's longest-running chart-topper to date.
What's even wilder is that his collaboration with Hikaru Utada, "JANE DOE," and his theme song for the live-action film "5 Centimeters Per Second," "1991," are also sitting pretty at #2 and #5 on the same chart. Talk about a total chart domination!
On the streaming front, "IRIS OUT" also crushed it, hitting #1 on the "Streaming Songs" chart for 8 consecutive weeks with over 16.23 million plays. Plus, Kenshi Yonezu made history on the Oricon Streaming Chart as the first male solo artist to snag 8 consecutive weeks at the top.
"IRIS OUT" also reigned supreme on the Billboard JAPAN "Global Japan Songs Excl. Japan" chart for 8 straight weeks, setting an all-time record for Japanese songs with a whopping 18.13 million overseas plays in a single week.
And get this: the track soared to #1 on the Billboard Japan Songs charts in 10 countries and regions worldwide, including South Korea, Singapore, France, the UK, Brazil, the US, Germany, Indonesia, and Malaysia. This marks the first time in Japanese music history that a song has simultaneously topped the charts in 10 overseas territories – a truly monumental, phenomenon-level achievement!
Taking an even closer look, it's clear that "JANE DOE," his collaboration with Hikaru Utada, is also crushing it, holding steady at #2 for 7 consecutive weeks. This means Yonezu has had two songs dominating the #1 and #2 spots for seven straight weeks – an incredibly rare feat! Not to mention, it previously hit #5 on the Billboard World Chart, the highest position ever for a Japanese language song.
As the theme song for "Chainsaw Man Reze Arc," "IRIS OUT" has ridden the film's hype wave, absolutely sweeping music charts across the globe. This record-breaking run solidifies "IRIS OUT" as a pinnacle in Kenshi Yonezu's illustrious music career. From Japan to the world, he's not only reaffirmed his creative prowess but also showcased the immense power of Japanese pop music on the international stage.
