The Jomon through Yayoi people used a unique Y-shaped shura which allowed them to transport heavy and large items such as timbers, trees or megalithic stone.

Abstract:

They had also developed a sophisticated technology involving a Y-shaped shura used for transporting heavy and/or large items such as timbers, trees or megalithic stone. Abstract: The Y-shaped lumbers of the chestnut trees were excavated at the Sakuramachi-Site in Oyabe City, Toyama, Japan in 1997. It is thought that the people of the Jomon period about 4000 years ago used the Y-shaped lumbers to transport heavy items such as giant trees. The positioning of Y-shaped lumbers in the history of sledges in Japan is discussed in this paper. The Y-shaped lumbers of the Sakuramachi-Site were compared with sledges excavated in Kitoragawa-Site of the Yayoi period in Higashiosaka City, Osaka Prefecture, Japan. It was confirmed that the Y-shaped lumbers of the Sakuramachi-Site is the oldest Shura in the world for the transportation of giant trees under the assumption that the Y-shaped lumbers at the Sakuramachi-Site are Shura

  1. When they made Osaka Castle, in order to transport large stones, they use
    large ships on the water, and “Konbu” Seaweed is used as lubricant for sledge on the ground.
    Dried Konbu was imported from Hokkaido, and used Konbu as lubricant was cooked to soup food and treated to blue workers.
    “KORO” log tree roller bearing was also used.
    Bamboo is also used as lubricant in Festival to steering man power dragging big festival car. Living bamboo is very oily.
    The big festival car has no steering mechanism for dragging fun.
