Why “Nobishiro” Is Back in the Spotlight
Most songs fade after a few years. Creepy Nuts’ “Nobishiro” keeps growing, which fits its title. On August 11, 2026, Sony Music Labels announced that the track had passed 300 million cumulative streams on Billboard JAPAN’s streaming chart. It is only the duo’s second song to reach that mark, after the global anime hit “Bling-Bang-Bang-Born.”
The song also got a new audience this summer. Since July 16, 2026, it has played in a TV commercial for the Honda N-BOX, one of Japan’s best-selling small cars. In the same campaign, a second N-BOX ad uses “Running Wheel,” a brand-new song the duo wrote for it. So Japanese TV viewers are hearing a 2021 song and a 2026 song from the same act, back to back, selling the same car.
If you know Creepy Nuts from anime openings, “Nobishiro” may feel different. There is no demon, ghost, or magic school here. It is a song about turning 30. Below, we explain what the lyrics are about, using what rapper R-Shitei said about the song on the radio, and the Japanese ideas you need to get the full picture.
▶ More music videos and live clips are on the official Creepy Nuts YouTube channel. The song is also available on Spotify, Apple Music, and other streaming services.
Who Are Creepy Nuts?
Creepy Nuts is a Japanese hip-hop duo made up of rapper R-Shitei (R-指定) and DJ/producer DJ Matsunaga (DJ松永). R-Shitei made his name in freestyle battle rap and was the first rapper to win Japan’s biggest MC battle tournament, the ULTIMATE MC BATTLE (UMB), three years in a row. DJ Matsunaga won the DMC World DJ Championships in London in 2019, the most famous turntablism contest in the world. Internationally, they broke through with “Bling-Bang-Bang-Born” (the opening of the anime Mashle) and “Otonoke” (from Dan Da Dan), and in April 2026 they played Coachella as part of their first North American tour.

Cultural Note: What Does “Nobishiro” Mean?
Nobishiro (のびしろ, usually written 伸びしろ) literally means “stretching room.” It describes how much more someone can still grow or improve. In Japan, it is a very common word in sports, school, and the workplace. A coach might say a rookie “has a lot of nobishiro,” meaning they are not great yet but have plenty of potential. The closest English is “room for growth” or “upside.” The important detail: it is normally said about young people, by older people. Keep that in mind, because the song flips it.
“Nobishiro” Lyrics Meaning, Section by Section
First, a bit about how the song was made. On August 10, 2021, the duo talked about the track on their late-night radio show, Creepy Nuts no All Night Nippon 0 (ZERO). DJ Matsunaga had sent R-Shitei a very simple beat built on one short repeating loop. R-Shitei then added melodies and a song structure that you would never guess from the beat alone, and the track changed a lot once his vocals were on it. Both said that some of their best work comes from this setup: a minimal beat that leaves R-Shitei free to move.
Cultural Note: All Night Nippon
All Night Nippon is a legendary late-night radio brand on Nippon Broadcasting System that has been running since the 1960s. Hosting a slot is a big deal in Japan, usually reserved for top comedians and musicians. Creepy Nuts hosted their own show for years, and it is where fans hear them explain songs, joke about their lives, and reveal behind-the-scenes stories. Much of what we know about “Nobishiro” comes from that show.
We won’t quote the lyrics here. Watch the official music video above while you read. What follows is based on R-Shitei’s own explanation, plus our interpretation, which we clearly label.
Part 1: The City and the Grown-Ups Who Used to Be the Villains
The song opens by linking two things: a city and “adults” (otona, 大人). According to R-Shitei, he lines up a city he once saw as the enemy with the grown-ups he once saw as the enemy, and then realizes that he is now turning into one of those grown-ups himself.
The city, he explained, is Tokyo. R-Shitei was born and raised in Osaka, Japan’s second big city, and later moved to Tokyo for work. For many people from Osaka, Tokyo is “the other side”: the capital, the center of the entertainment business, a place with a very different attitude. Now he lives there and is part of it.
Cultural Note: Osaka vs. Tokyo
Osaka and Tokyo have a friendly but real rivalry. Osaka has its own dialect (Kansai-ben), its own comedy tradition, and a reputation for being louder, warmer, and more down-to-earth. Tokyo is seen as the polished, corporate capital. R-Shitei still speaks in Osaka dialect, and his move to Tokyo is part of his story. So when he describes Tokyo as a city he once saw as a “villain,” Japanese listeners hear a whole regional backstory behind it.
He also pointed out that in hip-hop, “adults” are often used as a vague enemy: powerful people who look respectable but are up to something behind the scenes. On the radio, R-Shitei said he wanted to take a second look at that “adults are the enemy” view in this song.
Our reading: this opening tackles a question every rebellious rapper eventually faces. If you spent your youth rapping against adults, what do you do when you become one? The song doesn’t beat itself up about growing up, and it doesn’t mock its younger self either. It moves toward accepting that both are part of who he is. That may be why it never sounds preachy.
Part 2: Dropping the Labels
In the middle of the song, R-Shitei takes on the short labels we use to sort people. The examples he gave on the radio were words like otona (adult), kodomo (child), otoko (man), and onna (woman). He explained that he refuses to be neatly filed under any one of them. At 30, he said, he feels like a mixture that is hard to put into words.
This connects to a theme Creepy Nuts has carried from the beginning: the feeling of being “neither one nor the other.” In a 2017 interview with Real Sound, they talked about being in-between and how that position lets them fight with their music in more than one world. Put simply, they have long described themselves as belonging fully to neither the hip-hop scene nor the pop world.
Our reading: in “Nobishiro,” that in-between feeling shifts from music scenes to age. Thirty is neither young nor fully “adult,” and the song treats that not as being stuck halfway, but as freedom from being pinned down. That could also explain why teenagers love the song: they know all too well what it feels like to be called a “kid” when they don’t feel like one.
Part 3: Still Getting Better
The later part of the song is where the title idea takes over. On the radio, R-Shitei said that even at 29 he was still getting better at rapping and still learning as a person. At 19, he had tried hard to act grown-up and assumed that becoming an adult meant something would end. Now, standing right before 30, it felt less scary than he had expected, with no end in sight. The upbeat feeling of ee yan won out.
Cultural Note: “Ee yan” and Turning 30 in Japan
Ee yan (ええやん) is Osaka dialect for “that’s nice” or “not bad at all,” a relaxed, approving phrase. R-Shitei used it on the radio to describe his mood about turning 30. In Japan, 30 is often treated as a heavy milestone. The word misoji (三十路), meaning “one’s thirties,” can carry a sense of “no longer young,” and there is social pressure about career, marriage, and settling down. Turning that moment into an ee yan attitude is part of what makes the song feel fresh.
Here is the clever twist. As explained above, “you’ve got nobishiro” is normally something older people say to younger people. In this song, a man about to turn 30 says it to himself. Getting older is framed not as losing something, but as still being in the middle of growing. Our reading: this switch in perspective is what gives the whole song its brightness.
A Hidden Working Title: “Thirty Is the New Twenty”
In the same broadcast, R-Shitei revealed that an early idea behind the song was “Misoji wa hatachi” (三十路はハタチ), roughly “your thirties are your twenty.” Hatachi is the special word for age 20, which was the age of adulthood in Japan for decades and is still celebrated with a big Coming of Age Day ceremony. His point: the resolve to “become an adult” that people are supposed to make at 20, he felt he was only reaching at 30.
He also joked that while Japan was lowering the legal age of adulthood (from 20 to 18, which took effect in 2022), his own mental growth seemed to be going in slow motion. Our reading: the song is not about growing up fast. It is about growing at your own pace, which makes it a song for late bloomers too.
How the Duo’s Own Story Backs It Up
The message hits harder when you know their résumés. R-Shitei’s three straight UMB titles made him a battle-rap legend. DJ Matsunaga became the world’s top DJ at DMC in 2019, just two years before this song came out. So the person who made the beat had chased a world title on the edge of 30, and his partner is rapping that there is still room to grow. Our reading: the claim that growth doesn’t stop when you’re young is backed by their real lives. And given that they later headlined Tokyo Dome (February 2025) and played Coachella (2026), the song now sounds almost like a preview.
Cultural Note: Battle Rap and the DMC
In Japan, freestyle MC battles became hugely popular in the 2010s, helped by the TV show Freestyle Dungeon. The UMB tournament is the most respected of these events, and winning it three times in a row is a record no one had set before R-Shitei. The DMC World DJ Championships is a long-running global contest for scratch and turntable skills. A Japanese DJ winning it in London was major news in the DJ world. These two titles are the “credentials” behind the duo, and fans often bring them up when talking about the group’s long climb.
What the Duo Said About Making It
It Started with RHYMESTER’s “Trust Over 30”
R-Shitei has said more than once that the song’s starting point was “Trust Over 30” by DJ TATSUTA featuring RHYMESTER. RHYMESTER is one of the pioneering groups of Japanese hip-hop, and that track is about life past 30. According to THE FIRST TIMES, R-Shitei mentioned this inspiration again in his comment for the 2022 THE FIRST TAKE performance, and said he was glad the song reached people with no connection to the duo.
Our reading: one generation of Japanese rappers sang about being over 30; the next generation answered with its own version. That kind of passing of the torch is very hip-hop.
DJ Matsunaga’s Take
In the same set of comments, DJ Matsunaga said the lyrics are R-Shitei’s personal story, but he is happy that they connect with so many people. The two members are one year apart in age, and the song came from the moment when both of them were reaching 30.
Its Place on the Album Case
Japanese music writer Yu Aoki, in his note column on songs about age, reads “Nobishiro” as a pair with another Case track, “15sai” (“Age 15”). “15sai” is a darker look back at teenage pain, while “Nobishiro” is hopeful about getting older. Aoki sees them as two sides of the same 30-year-old point of view and suggests listening to them together.
Side by Side with “Running Wheel”
According to Real Sound, in their comment on the 2026 Honda campaign, Creepy Nuts said “Running Wheel” reflects where they stand now, and invited people to enjoy the contrast with “Nobishiro” in the other ad. A song about “still growing” at 30, next to a new song written after playing the world’s stages: the duo seems well aware of those five years in between.
How Fans Hear It, in Japan and Abroad
Sony Music’s August 2026 press release credits the song’s long life to its positive “still room to grow” message, and notes that TikTok posts using it are still coming. Our reading: it fits life’s turning points such as graduation, a first job, or a birthday, which may help explain why it keeps getting rediscovered.
Outside Japan, there is far less English-language discussion of “Nobishiro” than of the anime tie-ins like “Bling-Bang-Bang-Born” or “Otonoke,” at least within our research. English-language summaries usually translate the title as “room for growth.” The extra layers, like the weight of misoji or the change in Japan’s age of adulthood, rarely come through, which is exactly why we’ve unpacked them here.
The Takeaway: What “Nobishiro” Is Really Saying
“Nobishiro” treats turning 30 not as the end of youth but as a point somewhere in the middle. It accepts the city and the adults that once looked like villains as part of who you are now. It drops the neat labels people use to sort each other. And it openly enjoys the fact that you can still get better. For a rapper who grew up treating adults as the enemy, it reads like one honest answer to the question of what comes next.
Five years later, the same duo is playing to the world, and their “still growing” song is on Japanese TV again next to their newest single. That pairing feels like the song checking its own answer.
