Night lighting is designed based on Japanese Industrial Standards and National Police Agency guidelines, but it has not been verified that it is actually in accordance with the standards. In this study, the night lighting environment in the park was verified from the viewpoint of user safety. The illuminance was measured every 10m mesh in Suminoe Park and Sumiyoshi Park, which are thought to have many users at night. The measurement was performed separately for the leafing period and the defoliation period. At Suminoe Park in the leafing period, 75.6% of the main places with garden roads were below 5 lx and below the JIS standard. In addition, 53.1% of other places were below 1 lx and below the JIS standard. 72.9% at the main locations in Sumiyoshi Park and 34.3% at other locations were below the JIS standard. These illuminance deficiencies are considered to be able to be improved to some extent by plant management techniques.
