We’ve all had nightmare neighbors, but spare a thought for the residents of Kyoto’s Nishikyo neighborhood, who’ve spent the last decade putting up with one Kazunori Yokoi, a man who sounds like he could be a strong contender for the title of Japan’s worst neighbor. Yokoi, 61, was arrested this week after allegedly having spent the last decade tormenting his fellow residents by blasting his radio and playing his electric guitar at obnoxious volumes. As per Kyodo News, Yokoi has been the subject of multiple complaints over the years, and has continued making a racket despite “officers repeatedly warn[ing] Yokoi.” Apparently three of his neighbors, each aged somewhere between their 60s and 80s, have “developed health problems because of the prolonged noise,” including depression and, unsurprisingly, sleep deprivation. Another woman aged in her 60s allegedly developed tinnitus over the course of the two-ish years between April 2025 and Yokoi’s arrest. The report suggests that his electric guitar was measured between 80 dB and 90 dB. The former compares to the sound of a passing truck or motorcycle, or perhaps a police siren; the latter is more like a subway train or a power tool. Most scales also note that sounds above 85 dB are considered harmful.
