Kimura’s defense team fought for three years because he denied killing Kishida, according to Jiji, while the prosecution had requested a 15-year statement.
The reports were not immediately confirmed by a jury representative.
Suspected explosives, as well as pipe-like materials and resources were found at Kimura’s house during a police research after the attack.
At hearings during the trial, Kimura’s lawyers said his “purpose was to gain ( public ) attention” so his charge should be “inflicting injury” but not attempted murder, NHK said.
However, according to reports, the prosecution referred to the event as a “malicious evil act” and claimed the attacker was aware that his explosive was deadly.
According to previous reports, Kimura once filed a lawsuit challenging the age requirement for political candidates and the requirement that candidates must have at least US$ 3 million ( US$$ 19,700 ) to run for office.
Under Japanese law, candidates for higher property votes may get 30 or older, while the maximum time to work for parliament’s lower house is 25.
