timelesz Reveal New Visuals and Details for Upcoming Single “Kienai Hanabi”

timelesz has announced that their new single “Kienai Hanabi” (消えない花火; roughly “Fireworks That Never Fade”) will be released on July 29. Alongside the announcement, the group also unveiled new artist visuals and jacket photos.

Marking timelesz’s first true pop ballad in their current era, the song wraps the miracle of meeting someone in the fleeting glow of summer fireworks.

In Japan, fireworks are often tied to summer memories that feel almost suspended in time — festival nights, crowded streets, distant music, moments that feel endless even while you already know they will disappear by the end of the evening. That emotional contradiction seems deeply embedded into “Kienai Hanabi.”

The fireworks themselves may fade within seconds, but the feelings attached to them linger far longer, becoming memories people quietly carry with them long after summer ends.

Built around a delicate melody and bittersweet lyrics, the song carries the warm but painful idea that while fireworks eventually disappear from the sky, the moments shared together continue to burn gently within the heart. There is a quiet nostalgia woven throughout the track — the kind that settles in after summer nights end — making “Kienai Hanabi” feel less like a dramatic heartbreak song and more like a reflection on the beauty of temporary moments themselves.

With its nostalgic summer atmosphere, the track is set to color listeners’ summer memories — so please look forward to it!

The jacket visuals reflect the world of the song as well, balancing warmth with a subtle sense of fragility. The photos also showcase a different side of timelesz compared to their previous releases.

The release will also include extensive bonus video content. In addition to the “Kienai Hanabi” music video, fans can expect making-of footage and two different variety video features.

A special “Tour Venue Limited Edition” will also be sold exclusively at venues during the nationwide arena tour, beginning with the Aichi performances on the 16th. This version comes in an LP-sized package, allowing fans to enjoy large-format visuals of the group. Reservation details for each venue will be announced on the official website.

Further details regarding tracklists and purchase bonuses — including bonuses for purchasing all three standard editions together — will be revealed at a later date.
