Yoshida Yasei (吉田夜世, ヨシダヤセイ), formerly known as Yasson, is a vocal synth producer based in Hokkaido, Japan. He debuted in June 2020 with the song "Tayutau Hako no Naka de". He specializes in EDM and pop music, with some basic guitar skills. He became interested in becoming a VOCALOID producer after regularly listening to VOCALOID music and wanting to participate in the scene.

His producer name change came about because the name "Yasson" often led to misinterpretations, though "Yasson" remains a fond nickname among some fans. The name "Yoshida" was chosen from his real name, while "Yasei" was selected based on the total stroke count in his name, amounting to 8 and 5 strokes respectively.

His most popular song is "Override", which has reached over 17 million views on YouTube.

He was born on February 3rd.
