What happened

On June 9, 2026, Japanese manga platforms LINE Manga (a popular Japanese manga app) and ebookjapan made all 38 volumes of *Blue Lock* free to read for 24 hours. The franchise, written by Muneyuki Kaneshiro and drawn by Yusuke Nomura, has sold more than 60 million copies worldwide. The date became 'Blue Lock Day' through a Japanese number pun: 2-6 reads as 'blue,' 6 as 'ro' and 9 as 'ku,' spelling out the title. Organizers billed it a 'once-in-a-century' event.

Why it is trending now

The free day was the opening of a seven-day 'soccer manga feature' running June 9–17, with a different title unlocked each day (June 10 highlighted the manga *Days*). A coin-prize draw also runs alongside it, rewarding readers who sample three serialized titles. The timing stacks with bigger franchise news: an officially announced anime Season 3, *Blue Lock: Neo Egoist League*, and a live-action film starring Fumiya Takahashi set for August 7, 2026.

Together, they turned a giveaway into a wider 'jump-in point' moment.

How fans reacted

Most posts on X are campaign-style invitations using the phrase 'must-see for soccer manga fans,' nudging followers to read and enter the draw. Others explain the series' hook—an 'egoist' striker who scores by outcompeting teammates rather than the usual teamwork-and-effort sports story—prompting newcomers to say they'll check it out.

What to watch next:

Watch whether the daily free titles keep driving new readers through June 17, and how the momentum carries into the Season 3 anime rollout and the August 7 live-action film opening.

Japan context

For readers outside Japan

Blue Lock is one of the most internationally recognized sports manga of the moment, and Japan just gave readers a 24-hour window to read the entire series for free.

Blue Lock streams internationally as an anime and is published in English by Kodansha, so its name is familiar to many overseas fans even though this specific giveaway ran on Japanese platforms. 'Blue Lock Day' is built on a Japanese number pun (6/9), a common style of dajare (a Japanese pun) used to create themed promotional days.

The Japanese press releases confirm the scope—all 38 volumes, 60 million copies sold—and show that the free day was the launch of a longer soccer-manga feature rather than a standalone stunt.

The free reads ran on LINE Manga and ebookjapan, which are Japanese services, so access differs by region.
Japanese sources confirm the franchise's 60-million-copy milestone and the dates of the June 9–17 feature.
