The Asuka period spans the period from 593, when Empress Suiko ascended to the throne, to 710, when the capital was moved to Heijo-kyo. This was a time of great change for Japan, as various cultures, policies, and ideas were introduced to Japan with the introduction of Buddhism. It was also during the Asuka period that Japan promoted policies aimed at becoming a Ritsuryo state centered on the emperor. The late Kofun period overlaps with the early Asuka period, and while kofun tombs were constructed during the Asuka period, major changes occurred in funeral culture.

As regent to Empress Suiko, Prince Shotoku implemented political reforms by introducing advanced political systems and culture, such as the Seventeen-Article Constitution, the Twelve Ranks of the Crown, and the dispatch of envoys to the Sui Dynasty. According to the Nihon Shoki (Chronicles of Japan), he died in 621 (the 29th year of the reign of Empress Suiko) and was buried in Isonaga. There is a record that Prince Shotoku built his own tomb in 618, the year before his death, suggesting his strong attachment to his grave. Prince Shotoku's tomb is a circular tumulus approximately 50 meters in diameter and 10 meters in height, with a horizontal stone chamber made of intricately cut stone.

However, the "Simple Burial Order" issued in 646 subsequently regulated the size of kofun tombs, the time required for their construction, and the number of people required for their construction, resulting in the end of the large kofun tombs seen in the Kofun period.

According to the Taiho Code, enacted in 701, only those of high status were permitted to build tombs, and ordinary people were required to be buried in designated locations and could no longer be buried freely.

There is a record of a monk named Dosho being cremated in 700. This is said to be the first cremation in Japan. Later, in 702, Empress Jitō was also cremated. Cremation appears to have been a noble method of funeral performed only for the privileged class.

"Forest scattering" is a natural burial where the remains are returned to nature. It is similar to "tree burial," which involves burial at the base of a tree, but is slightly different. While "tree burial" involves digging a hole in the ground and burying the remains in an urn, "forest scattering" involves grinding the remains into a fine powder beforehand and scattering them in the mountains. The remains are not buried underground, but rather scattered over the ground like the "Grandpa Who Made Flowers Bloom." In the wild, grass grows and bare ground is rarely found, so the white remains are not left in one place. The powdered remains gradually return to the soil as they are exposed to wind and rain. Furthermore, while in a typical "tree burial," the remains are exhumed and interred after a certain number of years, in the case of "forest scattering," the remains cannot be manually retrieved, so they rest there forever. Japan has a long tradition of "mountain worship," which views the entire mountain as a sacred object. ・・・

"Ocean scattering" is a funeral method that has become popular not only in Japan but around the world. Scattering ashes into rivers is not permitted in Japan, so this method seems to be gaining popularity. It is particularly popular as a way to say goodbye to a deceased loved one, and services such as chartering a motorboat or cruiser to scatter ashes offshore are popular. However, the drawbacks of this method include the fact that the ocean is easily affected by weather, which can suddenly result in a cancellation on the scheduled date, and the relatively high cost of chartering a boat. Our company, SANKOTSUYAMA, offers an "Ocean Scattering Plan," which uses our small boat, eliminating the additional cost of chartering a boat. All costs are included in the price. Furthermore, "ocean scattering" does not necessarily require the services of a specialized scattering company. Individuals are not prohibited from scattering powdered ashes into the sea. However, scattering ashes is prohibited near fishing ・・・
