Daisenryo-kofun Tumulus (which is said to be the mausoleum of Emperor Nintoku)（ Ohosaka Prefecture）
The keyhole-shaped mound of 486 meters of tumulus length is built at the greatest ancient tomb in Japan about the middle of the 5th century.
Gross area: 464,123 square meters.
Please compare the size of this mound and a human being.
People are not visible even to a point.
Even if we might approach to it, it is visible only as a mountain.
When we see it from high up in the sky, this hugeness is known.
Could people make such a huge grave for only one man of power?
All primitive people could do is to obtain food and one day must have finished for obtaining food.
If the total construction cost of 79,600 million yen and 2000 people per day will be engaged in construction by OBAYASHI in 1985 at construction and it is a total of 6,800,000 people, trial calculation that it takes construction period 15 years and eight months has come out.
