On 10 February 1997, Shinichiro Azuma attacked two twelve-year-old sixth-grade students of Minami-Ochiai Elementary School, at around 16:35 near an apartment complex in Nakaochiai
district. The two girls were returning home when Azuma struck them in the back of the head. One of the injured girls required a week of treatment for her injuries.
Ayaka Yamashita On 16 March 1997, at around 12:25, Azuma bludgeoned ten-year-old Ayaka Yamashita, a fourth-grade student of Ryugadai Elementary School, near a residential building in Ryugadai, causing her death the following week. Ten minutes after the attack, Azuma stabbed and injured a nine-year-old girl with a 13-cm dagger outside of Tatsugaoka Park. for this... Please continue to protect me." As revealed in Azuma's
manuscript, "13 Years Imprisonment" ("懲役十三年"), "Bamoidōkishin" refers to an apparent deity, evidenced by the character 神 for "
kami," whom he claimed to have "created from hatred" in his childhood. The manuscript details a contract which would end with Azuma serving thirteen years in prison for committing murders as part of a "crime pact" to pledge allegiance with "Bamoidōkishin" in exchange for forgiveness of the same crimes. On 15 May, Azuma stopped attending his third-year class at Tomogaoka Junior High School after an incident two days earlier in which he had phoned a classmate for a meeting in the park and then punched him in the mouth, chipping some of the classmate's teeth by wrapping his watch around the fist. Azuma's parents regularly took him to a
child psychiatrist during this time. The assault was considered the high point in a number of other "eccentric delinquent acts" at Azuma's school, including stealing and burning other students' shoes, hitting people with a
table tennis racket and slashing bicycle tires with a
box cutter.
Jun Hase Just before 14:00 on 24 May 1997, while walking a street of Tomogaoka, Azuma encountered eleven-year-old Jun Hase, a
special education pupil at Tainohata Elementary School, where Azuma had attended primary education. Hase was lured to Tank Mountain in Taihata, where Azuma claimed that he would show Hase a turtle. There, Azuma overpowered Hase and fatally
strangled him with the boy's own shoelaces. He stole a
hacksaw and padlock from a nearby
co-op supermarket, then broke into an empty
television relay station on the mountain in which he hid Hase's body. Hase was reported
missing by his family the same evening. On 25 May, Azuma returned to the station, where he
beheaded Hase's body between 13:00 and 15:00. He further
mutilated Hase's head by stabbing out both eyes, cutting into both cheeks and unsuccessfully attempting to cut out the tongue. Azuma took the head and left Hase's body inside the station. Azuma used the term "vegetables" to refer to people around him; he had learned this term from his parents, who had once told him, "If you are nervous at your
sports day, picture the people around you as vegetables." According to Azuma, he wrote the word "SHOOLL KILL" because he believed it to be
English for "school killer." The note also included a symbol which Azuma later described as "inspired by the inverted
swastika of
Nazi Germany", after reading
Mein Kampf while in elementary school. == Investigation ==
