>>280476775 (OP)Toriko was good for a shounen. It actually had unapologetic MCs and characters that actually killed and manned up barring Komatsu, but he's a different kind of wankery. Anons here have said everything else but I'll more to why it failed.
First off early in the anime, during the Jewel Meat arc, there was an actual product placement that was hilarious bad. That was the first nail in the coffin.

The second and final nail in the coffin was the end of the 3rd season. They did an anime original ending so bad it actually tanked the sales of Toriko for tankobons.

From then on Toriko gradually was removed from the front covers of WSJ. Hell, even it's ending proclamation was printed so abysmally small to the right side of the mag. After that, it was like it never existed. Barely any author gave it notice for Jump anniversary except for Murata who snuck some Toriko in his overly large tribute works to WSJ.
Now you know what killed Toriko. It was the business workings of WSJ top heads and editor who forcefully pushed it to the top without it naturally grabbing audiences, a fucking product placement and an anime end so abyssmal by Toei that it cratered Toriko as a whole.
