Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we prove that the existence determination of a solution is NP-complete problem for Tasukuea, a kind of combination puzzle. Specifically, the proof is based on a polynomial-time reduction from Planar circuit SAT, which is an NP-complete problem.
