A 24-year-old man identified as Ryuji Kimura has been charged to court for allegedly throwing a pipe bomb at Japanese Prime Minister Fumio Kishida in April.
Kimura was charged with attempted murder, according court spokeswoman on Wednesday.
The suspect was said to have tossed an explosive device towards Kishida during a campaign event in western Japan.
Although, Kishida was unharmed after the attack, while Kimura was arrested at the scene.
The incident came less than a year after former leader Shinzo Abe was assassinated on the campaign trail.
A Wakayama district court spokeswoman told AFP Kimura “was indicted” on Wednesday.
