What Is “Diamond Fuji”?

Diamond Fuji refers to the breathtaking moment when the sun aligns perfectly with the summit of Mt. Fuji, shining brilliantly like a diamond.

This spectacular sight cannot be seen year-round—it only occurs when specific conditions of time, location, and alignment between the sun and Mt. Fuji are met, under clear weather. Because of these strict natural requirements, Diamond Fuji is an extremely rare and precious phenomenon.

Among the most famous viewing locations are Lake Yamanakako in Yamanashi and Lake Tanukiko in Shizuoka, which attract countless photographers each year hoping to capture this magnificent scene.

In some cases, when the reflection of the sun appears on the surface of the lake, visitors can witness the extraordinary “Double Diamond Fuji” (two suns visible—one in the sky and one reflected on the lake). In even rarer conditions, additional reflections create what is known as the “Triple Diamond Fuji”, making it a once-in-a-lifetime sight for photographers and nature lovers alike.

Origin of the Name “Diamond Fuji”
・The term was inspired by the “diamond ring effect” seen at the end of a total solar eclipse, when sunlight shines through the moon’s craters, resembling a diamond ring.
・It also reflects the way the sun sparkles like a diamond when it meets the peak of Mt. Fuji.

Where Can You See Diamond Fuji? | Recommended Viewing Spots

Rising Diamond Fuji

The Rising Diamond Fuji can be observed on the western side of Mt. Fuji, where the sun rises directly above the summit.

Famous viewing spots include Lake Tanukiko and Asagiri Plateau, both attracting large numbers of photographers every year. As the sun ascends diagonally from the upper right, it aligns with the peak of Mt. Fuji for a brief, dazzling moment—shining like a diamond.

Because this phenomenon occurs about an hour after sunrise, visitors need to arrive early in the morning and wait patiently for the right moment. The best time to witness it is during clear, windless mornings between winter and early spring, when the air is crisp and visibility is at its best.

Setting Diamond Fuji

The Setting Diamond Fuji can be viewed from the eastern side of Mt. Fuji, when the sun sets directly behind the summit.

Lake Yamanakako and Hana-no-Miyako Park are among the most famous spots, with Lake Yamanakako often referred to as the “sacred site of Diamond Fuji.” The area even hosts seasonal events such as Yamanakako Diamond Fuji Weeks, celebrating this natural spectacle.

During sunset, the sun slowly descends diagonally from the upper right to the lower left, meeting the summit of Mt. Fuji before vanishing in a burst of brilliant light. This rare moment lasts only about two minutes, making it especially captivating for photographers.

Compared to the rising version, the setting Diamond Fuji is easier to time and observe, as the movement of the sun is more visible. However, it can sometimes appear slightly before the official sunset time, so visitors should prepare early to avoid missing the chance.

For the best experience, it’s recommended to be ready at least one hour before the sun approaches the peak when photographing or simply enjoying the view.

Other Places to See Diamond Fuji — Not Just in Yamanashi!

Although Lake Yamanakako is one of the most famous viewing spots for Diamond Fuji, this breathtaking natural phenomenon can also be observed from various locations in Ibaraki, Chiba, Saitama, Tokyo, Kanagawa, and Shizuoka.

Below is a list of major Diamond Fuji viewing spots across the Kanto region, including approximate dates and viewing times. Many of these sites offer stunning sunset or sunrise views with Mt. Fuji glowing like a diamond.

The spots and dates listed above are general guidelines and may shift slightly due to factors such as leap years. For more precise planning, we recommend using the Diamond/Pearl Fuji Map, an interactive tool that calculates where and when to see Diamond Fuji as well as “Pearl Fuji” (when the moon sets over the summit of Mt. Fuji) based on the date you enter.
