Top 3 Winter Illuminations in Nagano Prefecture
Winter in Nagano Prefecture brings snow to temple grounds and castle moats, and with it, a tradition of evening illuminations. As temperatures drop, historic sites across the region install carefully designed light displays that transform familiar landmarks. These installations run through the coldest months, offering a great reason to venture out after dark. Here are the top 3 winter illuminations we feel are worth planning an evening around.
Matsumoto 
Nagano 
Azumino
Matsumoto Castle Illumination
Matsumoto Castle, one of Japan’s few remaining original castles, receives a seasonal light treatment each winter. Colorful projections and illumination are projected on the black walls and multi-tiered keep, with reflections spreading across the surrounding moat. The display typically incorporates seasonal themes, turning the historic site into a canvas of light.
The illuminated castle grounds stay open for evening strolls, combining the structure’s 16th-century architecture with contemporary light design. The display offers a different perspective on the site’s feudal history, especially on clear nights when the Northern Alps form a distant backdrop.
We offer a winter-exclusive guided tour for those interested in learning more about the castle’s history.
Zenkoji Temple Illumination and the Tomyo Festival
Zenkoji Temple, a 1,400-year-old site in Nagano City, draws pilgrims year-round, but winter adds evening lighting to its pathways and buildings. The illumination guides visitors toward the main hall, home to a hidden Buddha statue central to the temple’s significance.
The yearly highlight is the Tomyo Festival, a one-week event in February, when thousands of lanterns line the streets and colorful lights illuminate the temple complex in hues symbolizing peace. The festival blends religious observance with community participation. Local vendors offering food, art, and sake contribute to the atmosphere, making it an anticipated annual event.
We offer a limited-time samurai, temple and illumination tour during the festival for those willing to brave the chillier temperatures.
Azumino Alps Park Illumination
Set in the Azumino valley, Alps Azumino National Government Park transforms into a fairy-tale landscape with over 70,000 lights each winter. The displays form illuminated tunnels, garden patterns, and animal shapes set against the snow-covered Japanese Alps.
The park’s leisurely paths wind through the installations, with food stalls offering hot drinks and regional snacks. The scale and design make it particularly suitable for families, presenting a different aspect of Nagano’s valley landscape after dark.
