Sure, here is the translation:
Okay, no problem! Let me explain the phenomenon of "Aka Fuji" for you.
"Aka Fuji" (Red Fuji) – A Stunning, Exclusive Moment for Mount Fuji
Hello there! The term "Aka Fuji" conjures up vivid imagery, doesn't it? It's actually not referring to a type of apple (that would be Red Fuji apples), but rather a truly magnificent and beautiful natural spectacle that only occurs on Mount Fuji under specific conditions.
Simply put, "Aka Fuji" refers to the phenomenon where Mount Fuji's main body appears bathed in deep red hues under the light of the rising or setting sun.
Think of it as a magic show put on by nature. Normally, we see Mount Fuji with a white snow-capped summit and a blue-black body. But during an "Aka Fuji" event, the entire mountain looks as if set aflame, radiating a warm, crimson glow that's incredibly awe-inspiring.
Why Does the "Aka Fuji" Phenomenon Happen?
This isn't something you can see anytime. It requires several specific conditions to align perfectly:
- Angle of Light: It can only happen when the sun is just rising or about to set, positioned very low on the horizon. At this low angle, sunlight passes through a thick layer of the atmosphere before reaching Mount Fuji. During this passage, shorter wavelengths of light (blue, violet) are largely scattered away, leaving the longer red and orange wavelengths to reach and illuminate the mountain. This is the same principle that makes sunrises and sunsets appear red.
- Bare Mountain Body: This is crucial! The classic, fully red appearance of "Aka Fuji" requires that the summit snow has melted away, revealing Mount Fuji's inherent reddish-brown volcanic rock and soil. This natural "red canvas" provides the best reflectivity and most intense color when hit by the red light. If too much snow remains on the summit, the result appears pinkish and is called "Beni Fuji". While also beautiful, "Beni Fuji" is subtly distinct in concept from "Aka Fuji".
- Clear Weather: Absolutely! You need perfectly clear skies. Thick clouds blocking the sunlight will prevent this "light and shadow spectacular" from happening.
When Is It Easiest to See "Aka Fuji"?
Understanding the principles above, you can probably guess the best times to witness it:
- Season: Late summer to early fall (roughly late August to early September).
- During this period, the snowcap on Mount Fuji has largely melted, revealing the reddish-brown mountain body.
- Also, the air becomes drier and clearer, offering high visibility and better sunlight penetration.
- Time: Sunrise.
- While it can happen at sunset, the most typical and spectacular "Aka Fuji" usually occurs during those fleeting minutes surrounding sunrise. When the first rays of sunlight peek over the horizon, they instantly dye the slumbering Mount Fuji a fiery red – a sight coveted by photographers and visitors alike.
The Meaning of "Aka Fuji" in Japanese Culture
In Japan, "Aka Fuji" isn't just a beautiful natural sight; it's also seen as a very auspicious symbol.
The most famous depiction is in the ukiyo-e work "South Wind, Clear Sky" ("Gaifū kaisei") by the Edo-period master Katsushika Hokusai. This print is the quintessential artistic image of "Aka Fuji," featuring the massive red Mount Fuji radiating power and vitality.

Because witnessing "Aka Fuji" is so rare, it's believed that those who see it will receive good fortune, such as thriving business, protection from misfortune, or the fulfillment of wishes. Consequently, many people hang paintings or photos of "Aka Fuji" in their homes, hoping to invite good luck.
In summary, "Aka Fuji" is a serendipitous, breathtaking visual feast orchestrated by sunlight, season, and Mount Fuji itself. If you have the chance to travel near Mount Fuji in late summer to early fall, consider waking up extra early – you might just encounter this fortunate red miracle!
