His early independent films, such as Violent Men and The Wind Shall Blow, received accolades at local film festivals, signaling his promise as a creative storyteller.
Throughout the 2000s, Shiraishi established himself in the horror video market with entries in the Honto ni Atta! Noroi no Video series. His breakthrough came with the critically acclaimed Noroi, which gained international recognition for its chilling realism and unconventional narrative. In the 2010s, he transitioned into higher-budget commercial horror with titles like Funouhan (2018) and Hell Girl (2019), while still nurturing his passion for offbeat, experimental cinema. Shiraishi remains a prominent figure in Japanese horror, known for pushing genre boundaries with his unique voice and dark imagination.
