Plot
Light Yagami writes Yoda's name into the Death Note to test its effects. Light writes that Yoda will make it to a nearby restroom and collapse from cardiac arrest caused by the Death Note.

On December 19, Yoda walks into the prison's restroom and dies.

Film series
The character is renamed Tobe in the film series, but otherwise, the character and the circumstances of his death are the same. The character is not actually seen, but a photo shows his body's outline on the bathroom floor.

TV drama
The character is renamed Sankichi Setada (世田多三吉, Setada Sankichi) in the 2015 Death Note television drama, but he is otherwise essentially the same as in canon. Setada is a death row inmate in Nagoya. He escapes his cell to a staff bathroom and dies of a heart attack.

Trivia

 * In addition to Yoda, Light's tests also work on Masaaki Shirami and Ken Yadanaka. His tests fail on Shiniichiro Yamasaki, Yuzo Butsura, and Hitoshi Kabeoka. The next day, he does another successful test on Matsushiro Nakaokaji.
