He was 68.

He created the Dragon Ball animanga series and was the character and monster designer of the Dragon Quest franchise and Chrono Trigger, among others. This leaves only Yuji Horii, the scenario writer of DQ (composer Koichi Sugiyama died back in 2021), and it seems the twelfth promised mainline entry (The Flames of Fate) is now far greater vaporware than it was before, and since Toriyama to me is somewhat irreplaceable (and Sugiyama too to an extent), I doubt it will become a Franchise Zombie like other game franchises have become (i.e. Final Fantasy). Rest in peace, Toriyama-san.
