Shueisha just rolled out a new English-language simulpub website/app (called MANGA Plus) that provides the latest chapters of One Piece (and many other Jump titles) for free. Kind of like Viz's recent SJ overhaul? Minus the "vault"? But…
The selling point this time is that it's GLOBAL. Every country in the world except Japan, S.Korea, and China.
Article about it:
-same ENG translations used by Viz (Stephen's, for OP!), when it's a series Viz already does
-100% simul-release (same day/time as Japan)
-first and last chapters of a given series are free, and you can also purchase digital volumes
-Spanish version coming next month
