The mirage: where and when蜃気楼
Mirages show over Toyama Bay from mid-March to early June, most often in April and May. On a good day a layer of warm air over cold water bends the light and the far shore looks stretched or turned upside down. Seeing one is said to bring good luck.
Watch from the designated viewing point on Shinkiro Road (しんきろうロード), the coast road from Uozu Port toward Kyōden, from the observation deck at the Buried Forest Museum, or from the car park at Umi-no-Eki Shinkiro (海の駅 蜃気楼). The usual window is late morning to about 16:00 on a warm, clear, calm day, with air above about 18 °C. Uozu city posts a forecast, and the museum’s website links live cameras.
