Shakotan Peninsula: A super difficult place for boat traffic! Shakotan Peninsula Coastline Topography
\nSince the Japanese center symbolized by Abe Hirao came as far as the Goshi area, could the Sapporo area have participated in Japanese history from the Heian period if shipbuilding operation technology had been developed a little? …<\/p>\n

In the history of Japanese transportation, the Sea of Japan maritime transportation basically played the leading role. The fact that Abe Hirao’s northern expedition was able to travel as far as Hokkaido with a fleet of 200 ships indicates that the technology of maritime transportation had developed to that extent in 659. The Japanese fleet’s expedition to the Battle of Hakuchon River immediately after the Battle of Hakuchon also indicates this.
\nAfter the defeat at the Hakuchon River, Abe Hirao was appointed as the chief of Dazaifu, and was assigned as the secretary of defense against the combined fleet of Tang and Silla, which was expected to attack Japan. This shows that he and his forces were the most advanced technological group in maritime transportation at that time.
\nAlthough Japan’s maritime transportation network may have functioned in the area up to the Shakotan Peninsula, for a long time afterwards, no traces of the history of the area north of the Shakotan Peninsula and the Ishikari Bay area, including Sapporo, appeared. As mentioned earlier, the area north of Cape Kamui, at the tip of the Shakotan Peninsula, was considered a “no women’s area” and was ignored by Japanese society as an outcast area.
\nIf the Japanese Yamato regime had turned its main direction of expansion toward the north in the direction of the Abe-Hirau Northern Expedition, instead of moving in the direction of increased tensions with the Korean Peninsula, such as the Hakumura River, Japanese history might have developed in a completely different way. The photo above shows the rough sea and coastline of the Shakotan Peninsula. I have juxtaposed an imaginary image of a ship transporting a large number of soldiers at that time against such a difficult place. This is an illustration of a European wooden ship from a Wiki image of the time, but I imagine that the Japanese Abe-Hirau fleet was similar in appearance.
\nSince they were able to build and operate such ships to move and march in the Sea of Japan, it would have been possible to develop the Ishikari Bay area beyond the Shakotan Peninsula, no matter how difficult it was, by further advancing and developing their technology. Looking at the present 150 years since the Meiji era, when Sapporo was designated as the capital of Hokkaido and development began, it is regrettable that the potential of the region has not been fully utilized. Looking at examples such as the development of Otaru, which was even called the “Wall Street of the North,” we can see that considerable development could have been expected during the Heian period from 659 to the present.
\nWell, the Oshu Fujiwara government acquired the fruits of this development and made it a major factor in maintaining its own government. However, it seems that the Oshu Fujiwara were rather strongly oriented toward the Hidaka area from the Tomakomai vicinity. Traces of trade with the Ainu community can be found in these areas.
\nNow, I am going to Tokyo Big Sight for the “AI Artificial Intelligence EXPO” starting today. As I am using AI in my new business, I would like to get acquainted with the latest information at the booths of cooperating companies.<\/p>\n","protected":false},"excerpt":{"rendered":"
