Relentless Probe in Kyoto Child Case Exposes Suspect Yuki Adachi’s Cover-Up Attempts

Even after sunset, visitors continued to come to pay their respects

Even after the sun had set, people did not stop coming to offer their condolences.

This case involves the body of a sixth-grade elementary school student, Yuki Adachi (11), who was abandoned in a mountainous area in Sonobe-cho, Nantan City, Kyoto Prefecture. An offering table was set up at the entrance to the mountain path where the body was discovered.

When a reporter from this site visited, the offering table had not only bouquets of flowers, but also snacks such as potato chips and drinks such as Calpis. The offerings piled high on a small wooden table conveyed how many people were mourning Yuki’s death.

A man in his 50s who visited from Osaka said, “It was such a heartbreaking incident that I came here straight after returning from Minamisanriku Town in Miyagi Prefecture. Even if only to lay flowers.” He spoke, occasionally struggling to find words, sharing his feelings.

“Since the arrest on April 16 of the father, Yuki Adachi (37), on suspicion of abandoning a body, various facts have begun to come to light during questioning. One of them is the previously major mystery surrounding how Yuki’s body was discovered. The body was found in an area where people go for wild vegetable gathering, and it has been confirmed that local residents were still entering the surrounding woodland to gather wild plants even after March 23, when Yuki went missing.

The fact that the body was found in such a place initially felt abrupt and difficult to explain. However, during questioning, it became clear that the suspect, Yuki Adachi, had moved the body from place to place. During that process, suspicion has also emerged that it was temporarily hidden in a public restroom near his home. Yuki’s home was a large household where four families lived on the same property, but the suspect is believed to have concealed the body so that it would not be discovered by his family,” said a reporter from a national newspaper’s social affairs department.

“I didn’t realize he was the father.”

The people Yuki Adachi’s father, Yuki Adachi (suspect), tried to deceive were not limited to his family. On the very day the first piece of evidence—a backpack—was discovered, he went to work as usual, maintaining a composed facade. Furthermore, it has been confirmed that on March 31, he visited a nearby cake shop to distribute missing-person flyers for Yuki.

In fact, this site obtained surveillance camera footage from that time. It shows the suspect calmly handing out flyers.

However, cracks in his behavior were also beginning to show.

“When he visited the cake shop, the suspect did not introduce himself by name. Because of this, the staff did not realize he was the father. Moreover, when a staff member asked whether the posters should be displayed outside or inside the shop, he bluntly replied, ‘Either is fine,’ and appeared unenthusiastic about the search,” said an investigative source.

While living a normal daily life in front of his family and presenting himself outwardly as a grieving parent, his concealment efforts were eventually dismantled by a determined investigation.

“From his reaction when the school informed him that Yuki was missing, to his behavior during flyer distribution, and even traces of deleted footage found in his car’s drive recorder, various suspicious points led the prefectural police to advance their investigation.

Because he was acting while hiding things from his family, his range of activity was likely limited. Still, items such as the backpack and shoes were found in the mountains along the road he used between his home and workplace. The backpack showed no signs of exposure to wind and rain, which was clearly unnatural. Perhaps due to panic, his concealment efforts gradually became more careless,” said the same source.

Four days have passed since the suspect’s arrest, and the full picture of the case is gradually becoming clearer.
