It is a renowned location for observing the 'Diamond Fuji' phenomenon when the sun aligns with the summit of the mountain.
The adjacent road, the Hakone Turnpike, is frequently used as a filming location for automotive commercials and media.
The structure is positioned on the outer rim of the massive Hakone volcanic caldera.
Mt. Taikan Observation Deck offers a panoramic vantage point situated atop the Hakone caldera rim, providing an unobstructed view of Mount Fuji and Lake Ashi. The site serves as the terminus for the Hakone Turnpike, a popular winding toll road favored by driving enthusiasts. A prominent on-site facility, the Sky Lounge, functions as a combined restaurant and observation area with floor-to-ceiling windows. The elevation allows visitors to look down upon the clouds, a phenomenon frequently occurring in the morning. The location acts as a geographical gateway between the Yugawara and Hakone regions. Weather conditions frequently change due to the high elevation, often obscuring the mountain vistas within minutes.
The terrace area directly outside the Sky Lounge offers the most expansive, unobstructed frame for Mount Fuji photography.
Bring a windbreaker or additional layers, as temperatures are significantly lower here than at sea level.
Check the live camera feed on the official website before traveling to ensure cloud cover is not obscuring the view.

Do not rely on the view if the weather forecast indicates high cloud cover or rain, as the visibility of Mount Fuji can drop to zero.
