Zao Snow Monsters (Juhyo)
Every winter, the fir trees near the summit of Zao Mountain are transformed into towering snow sculptures known as juhyo — literally "ice trees" or snow monsters. The phenomenon occurs when supercooled water droplets from clouds freeze onto the branches in repeated layers, encasing the trees in thick white armour and turning the mountaintop into a surreal, otherworldly landscape. Viewed from the Zao Ropeway or during night illumination events, the snow monsters are among the most photographically striking natural phenomena in Japan. The season runs from late December through February, depending on conditions.

Bunshokan — Yamagata Prefectural Museum
Bunshokan is a striking red-brick building completed in 1916, originally serving as the Yamagata Prefectural Office and Assembly Hall before being designated an Important Cultural Property of Japan. The Taisho-era Western-style architecture, complete with a central clocktower, stands in sharp contrast to the castle walls of the adjacent Kajo Park, offering a window into a different chapter of Yamagata's history. Today the building functions as the Yamagata Prefectural Museum of Art, housing rotating exhibitions and permanent displays, and remains one of the most recognisable landmarks in the city.
