The Okayama prefectural police aim to increase the number of these types of workplaces to help improve the work-life balance of police officers. At the Masatsu residential police box in Okayama, Takanari Miyoshi and his wife Kaori, both 27-year-old sergeants, share the duties of serving about 3,000 households. They support each other in their duties, such as patrolling their assigned areas. Both musicians met as members of the prefectural police band and were wed in June 2021. However, they had conflicting schedules and became concerned they would spend more time apart than together, so Takanari requested to be assigned to the same police box as his wife.
