Moon Path

It’s definitely one of KAT-TUN’s hidden gems.

It starts off like a ballad, and just when you think it will stay somber, the flowing sound as the song progresses comes to express hope.

Many fans are moved to tears by this track.

I’m one of them, too.

Freeze

The song they performed before their debut is mostly rapped by the members.

I think it’s a track that brings out KAT-TUN’s toughness.

As it heads toward the end, the tempo picks up and the excitement rises, so you can listen without getting bored.

Kusabi -kusabi- (Piano) KAT-TUN with lyrics

Their first song as four members.

The title, “Kusabi” (Wedge), carried a somewhat suggestive meaning for fans.

Since Akanishi and Kamenashi had been the main vocalists, people worried whether the four of them could handle it, but there was no need to worry at all—especially Nakamaru’s voice is distinctive and addictive.

I really want you to listen to it.

SIGNALKAT-TUN39rank/position

Released as KAT-TUN’s second single in 2006, “SIGNAL” was used as a song for a NTT Docomo commercial around the time of its release.

Many people probably remember not only the commercial featuring the KAT-TUN members, but also the catchy chorus that played in it.

While their debut single “Real Face” is likely their most widely recognized song, this track is also an important one that helped bring them into the public eye.

4U

A hidden gem that was included only on the standard edition of the mini-album “Kusabi” released in November 2013.

Amid a lineup of tie-in tracks and hard-hitting numbers, this song is placed toward the end of the album, serving to evoke a warm, gentle glow.

The lyrics convey the inevitability of the encounter and deep gratitude toward the other person, and it seems to carry messages of “bond” and “connection” as the group, now a four-member formation, embarked on a fresh start.

Set to an urbane J-pop sound, the members’ distinct vocal timbres blend beautifully, giving a palpable sense of the group’s depth.

KAT-TUN – Ain’t Seen Nothing Yet [Official Music Video (YouTube ver.)]

A refined piano intertwines with restrained beats to create a medium-tempo number that exudes mature allure and nuance.

It stands apart from their previously wild and aggressive image, captivating listeners with a polished, sophisticated charm.

Produced as the lead track for the album “Honey,” released in March 2022, it served as a symbol for the project as a whole, with multiple versions of the music video unveiled ahead of the release.

Now a trio, the members’ individual expressiveness shines through in this track, making it ideal for quietly immersing yourself on a calm night or sinking into a chic, urban mood.

BLESSKAT-TUN42rank/position

BLESS

A track included on the standard edition of the mini-album “Kusabi” released in November 2013.

This period marked an important turning point as the group moved forward as a four-member unit.

The song is a lyrical medium-tempo tune that delicately traces fragments of memory to portray lost time and feelings for someone dear.

Its clear, transparent vocals and beautifully spacious arrangement convey both poignancy and warmth at the same time.

While they’re often associated with intense dance tracks and rock numbers, introspective and emotional songs like this are also immensely compelling.
