What's the slope of the Mt. Fuji Subashiri trail?

I wanna know the slope of the Mt. Fuji Subashiri trail because I heard it has the least steep slope.

Reply: You've asked a great question, and according to my calculations, the % grade of Mt. Fuji's Subashiri trail is 26.1%.

That compares to 21.6% for the Kawaguchiko trail, 29.9% for the Gotemba trail, and 27.5% for the Fujinomiya trail.

And according to mtfujiguide.com, the estimated hiking time for the Kawaguchiko trail (the least steep slope) is 5 hrs., which is 10 min. less than for the Subashiri trail.

Since initially receiving your inquiry, I've since put this Mt. Fuji trail steepness info along with trail hiking distances & hiking times on my Climbing Mt. Fuji FAQ page here: https://www.garyjwolff.com/climbing-mt-fuji.html#31

Thanks for your inquiry.
