In its original weekly publication, the final chapter of Jaco the Galactic Patrolman — Akira Toriyama’s new one-shot-turned-Dragon Ball-prequel — indicated that a collected print edition of the manga would be coming in January 2014.
January came and went, and along with it went Jaco from all listings of upcoming releases from Shueisha. One Japanese fan in particular seemed to get a hint out of Shueisha that it had been delayed until April, but there had been no formal, public confirmation from the publisher.
It turns out that the April timeframe was indeed true, as Shueisha’s latest listings now confirm a 04 April 2014 release date.
Jaco the Galactic Patrolman ran from the 2013 #33-44 issues of Weekly Shōnen Jump in Japan, and also saw a simultaneous digital release in English by Viz. There is currently no word from Viz on a collected English release either in print or digital form. Jaco is currently receiving a “Voiced Comic” (“Vomic”) from Shueisha in conjunction with the TV program “Saikyomi JanBANG!”
