Trivia, insights & behind the scenes
This marks the first theatrical Doraemon remake since 2014's Stand by Me, with Yajima specifically requested by Fujiko Pro to honor the original 1982 director Tsutomu Shibayama's spirit.
The 1982 original premiered during Japan's economic bubble, making its treasure-hunt fantasy aspirational; the 2026 version reframes wealth through environmental collapse anxiety, reflecting forty years of shifted national psyche.
