back number is a prominent three-member Japanese rock band that originated in Gunma Prefecture, Japan. The group consists of lead vocalist and guitarist Iyori Shimizu, bassist Kazuya Kojima, and drummer Hisashi Kurihara. Since their formation, they have become known for their emotional depth and ability to capture the nuances of romance and everyday life in their music.
The band achieved mainstream success through their consistent ability to produce chart-topping hits that resonate with a wide demographic in Japan. Their breakthrough was propelled by several singles that were selected as theme songs for popular Japanese television dramas and commercial films. This cross-media exposure helped them transition from the indie scene to becoming one of the most successful rock acts in the country.
On their digital channels, the band primarily shares high-quality music videos, live performance clips, and promotional content for their latest releases. Their content style is characterized by the same melancholic yet hopeful aesthetic found in their lyrics. They are best known for music videos that feature cinematic storytelling, often complementing the emotional themes of their songs.
The band's commercial activity is centered around their music production, extensive concert tours, and official merchandise. They have established a strong brand within the Japanese music industry, leading to numerous partnerships where their music is featured in major advertising campaigns and film soundtracks. These collaborations have been vital in maintaining their presence in the mainstream market.
No reliable public estimate exists for the band's total net worth, as Japanese musical acts typically keep financial details private. Their income is generated through physical and digital music sales, publishing royalties, and large-scale domestic tours. They also benefit from licensing their songs for use in television series, movies, and commercial advertisements.
The band is renowned for their signature work on soundtracks for various Japanese dramas and films. Their discography includes numerous hit singles that have reached the top of the Oricon and Billboard Japan charts. Their songs are often praised for their lyrical relatability and have become staples of modern Japanese pop-rock culture.

They are also a staple on Japanese music television programs and perform at major festivals across Japan. Their music is widely available on all major global streaming platforms for international listeners.
A major milestone for the band is reaching over 2.1 million subscribers on their official YouTube channel. They have achieved multiple platinum certifications for their albums and singles in Japan. Their consistent presence at the top of national music charts confirms their status as one of the leading rock bands of their generation.

back number is based in Japan and posts in Japanese. For brands that usually means the core audience follows the same market and language, with a long tail from everywhere else — big accounts rarely stay local.
The content sits in music and movies & tv, so the people watching are self-selected for those interests. That is the useful part of a niche profile: a mid-size account inside the right category often beats a much larger general account, because the audience already cares about the subject.
If you need the same audience profile in another market, the country and language lists on CreatorFanBase let you line up comparable creators side by side instead of guessing.
If you are shortlisting back number for a campaign, these are the facts worth carrying into the brief. Everything here is stored data, refreshed on a schedule rather than typed in once.
A practical sequence: check the lead platform matches where your buyers are, check market and language, open the official account to see recent posting frequency, then ask for a media kit and rate card directly.

back number's counts come from the platforms themselves via Apify YouTube public channel and are refreshed on a schedule; the most recent check was Oct 14, 2026. When a platform blocks a read, we keep the last verified number and show where it came from instead of filling the gap with an estimate.
Large jumps are treated as suspect: a sudden drop past our safety threshold is held back for review rather than published, which is why the numbers here tend to be lower-drama than screenshots circulating elsewhere.
