Weathered signs from five years ago stand forlornly on a bank of the Tama River in Kawasaki, politely asking visitors to refrain from laying any more flowers of condolence so they don*t accidentally catch fire.

But the scene is otherwise absent of any reminder of the shocking incident that happened here five years ago.

Thursday marks the fifth anniversary of the high-profile slaying of 13-year-old Ryota Uemura, a Kawasaki schoolboy who was found dead 〞 and naked 〞 on the riverside after he was repeatedly forced by a gang of three local teens to swim on a freezing February night in 2015 and had his neck slashed with a box cutter, a detail that evoked in the minds of many the gruesome fate of journalist Kenji Goto, who had been murdered by the Islamic State just weeks earlier.
