Near the observatory, Kagami-numa’s thawing snow can look like a white pupil ringed by water—the “Dragon Eye.” Hachimantai Visitor Center traces the nickname to Taiwanese visitors who shared it on social media in 2016.
Today’s observatory is the third: its predecessor was built in 1986 for the park’s 30th anniversary. The replacement project stalled after the contractor went bankrupt; the current structure was completed in 2014.
At 1,613 m, Hachimantai’s summit is no sharp pinnacle: it rises as a broad, gently sloping volcanic plateau dotted with low peaks and crater lakes. The observatory stands on this unusually level high ground.
A plaque at the summit recalls writer Kyūya Fukada, whose Japan’s 100 Famous Mountains praises Hachimantai for wandering its highlands rather than chasing a dramatic peak. Fukada first crossed the mountain on skis in 1939.
One local place-name legend credits Sakanoue no Tamuramaro with naming Hachimantai: admiring the scenery, he honored Hachiman Daibosatsu. Local sources tell this as a legend, not established history.
On a clear day, the summit viewpoint can reveal northern Honshu’s volcanic neighbors, including Iwate-san and Chōkai-san. You’re looking out from Hachimantai’s 1,613 m summit.
