These declines were prominent during the state of emergency from April to May 2020, particularly in pandemic areas. HRM and POEM in nonpandemic areas were relatively unaffected. From 2019 to 2020, there was a 0.4% (254\u2013248) decrease in POEM cases within the prefecture, but the number outside the prefecture decreased by 33.6% (372\u2013247).
