He was regarded as one of the most important pioneers of the Thai voice acting industry and was credited with popularizing Thai-dubbed anime throughout Thailand in the 1980s and 1990s.
Unfortunately, despite his relatives' pleas for him to take some time off, Kaiwan refused to heed their advice and continued to work tirelessly without allowing himself proper rest.
As a result of his relentless dedication, Kaiwan's health deteriorated, leading to episodes of seizures and trance-like symptoms on June 24, 2022.
Recognizing the seriousness of the situation, his relatives came together to assist him and promptly brought him to Sam Chuk Hospital for treatment.
Tragically, despite the efforts made by the medical staff, Kaiwan's condition worsened, ultimately resulting in his passing.
