Jomon Period, Sannai-Maruyama Coastline Fluctuation Mura and Living Condition-9
\nThe Jomon period (7,000 to 6,000 years ago), the Jomon sea advance peak (15,000 years ago), and the present coastline and environmental reincarnation. …<\/p>\n

The last two days have been interrupted by the news of my new series of articles in “Shinken Housing DIGITAL” and the heavy snowfall in Sapporo caused by the Ishikari Bay Low, but I am back to the “Mura to Izakaya” series from today.
\nHowever, the Ishikari Bay Low is still raging, and it is snowing heavily again today. So, I’m going to go ahead and plow the snow around my house again (laugh). I’m looking out the window right now and am once again stunned. I will probably post today’s blog around 7:00 a.m.
\nFinally, I’m done. It took me a full hour and a half. This winter has been a tough one. According to yesterday’s data from the weather bureau, the snow depth in Sapporo (indicating the depth of snow accumulation at the present time) was 93 cm at Nishino, which is close to where I live in Nishi Ward, as of 09:00 on February 23, and 83 cm for a normal year. Today’s amount will be added to that, so we will warmly wait for the 9:00 announcement (tears).
\nWell, I’m about to get down to business, but it’s been a long time and I’m feeling a bit drained of energy.
\nI have become strongly obsessed with the Mura’s livability series and the case study of Sannai-Maruyama. The discovery of this site began in earnest with a survey in 1992, so it was only 30 years ago. During my lifetime, its discovery and its study have evolved. I believe that this is an extremely monumental discovery in the history of the Japanese archipelago.
\nThe map above shows the coastline of Sannai-Maruyama at the height of the Jomon sea advance (roughly 7,000 to 6,000 years ago). The distance between the coastline and Sannai-Maruyama during this period is estimated to be about 1.3-1.6 km. The nearest river, the Okidate River, which flows toward the coastline, is only 350 meters away.
\nIt is clear that the largest representative “village” of the Jomon period, Sannai-Maruyama, was easily accessible from the river to the ocean. This is an extremely important factor in securing food supplies and in the trade relations between the villages. Furthermore, as we saw the other day, the six-pillar structure may have been the world’s tallest “skyscraper” of its time, with an estimated height of over 14 meters. It must have been seen from a great distance by ships passing in the distant waters of Aomori Bay. It is easy to imagine the interaction with the island of Hokkaido, which is located on the opposite shore.<\/p>\n

Furthermore, this imaginary map shows the northern Tohoku-Hokkaido area around 15,000 years ago, before the Jomon sea advance began and the earliest confirmed traces of the Sannai-Maruyama Mura. In such a period, rivers would have played a more significant role. Even though the coastline has receded to this extent, traces of humans can still be found at Sannai-Maruyama because of the abundant harvesting resources such as chestnuts. It is also possible that traces and remains from this period lie in the depths of the Aohan Strait.
\nThe depth of human history that established the Mura makes me feel dizzy.<\/p>\n","protected":false},"excerpt":{"rendered":"
