・Since all trade risks at that time were borne by Song merchants, it was not the Japanese who obtained huge profits from it, but Song merchants (p19)
・The reason why Japanese people were unable to participate in trade was that shipbuilding and navigation techniques did not develop after the abolition of the Japanese delegation to the Tang Dynasty in 894 (p20)
・The Taira family gained huge wealth by adopting a monopoly trade system; other examples include Ashikaga Yoshimitsu, Satsuma Domain, Portugal, and the Netherlands (p23)
・Song merchants hid in the Imperial Court and began to trade with the private sector (temples, shrines, aristocrats) (where payment was slow and bought cheaply), and this became smuggling (private trade) (p27)
・As a condition for earning huge wealth through trade, 1) the unit sales price is high, 2) the shape is small, and 3) the quantity is large (p30)
・Taira no Kiyomori developed the Setouchi route at his own expense (staying in Owada) so that Song ships, which have much deeper bottoms than Japanese ships, can safely enter the cabin (Yamashiro, Yamato, Kawachi, Izumi, Settsu) (p41)
・By moving the center of trade from Hakata to Kobe, they tried to make a major revolution by shifting trade practices from Song to Japan (p46)
・Ashikaga Yoshimitsu built Kinkakuji and invited the Imperial Envoy of the Ming dynasty, which was difficult since Imperial Prince Kaneyoshi of the Southern Court, who was based in Kyushu, traded with the Akira as the king of Japan until the unification of North and South Korea was carried out in 1392 (p54)
・The Battle of Sekigahara was an Asian trade proxy war where the Eastern Army used Dutch artillery and the Western Army used Portuguese artillery, and it was a battle between Protestant Protestant countries and the Catholic Old Empire (p56)
・As a mystery in Japanese economic history, the barter economy using silk and rice as a means of exchange changed to a monetary economy in about 10 years (1160-70) (p58)
・Taira Kiyomori continued to buy Song coins, but the Imperial Court issued a ban on use (1187,89,92,93), but there was no effect and Song coins were used until the Sengoku period (p60)
・In North Korea, where denomination was carried out, money was no longer trusted (there was an exchange limit), and as a result, prices rose and became hyperinflated (p86)
・Ancient Japan failed in denomination because the new currency was of poor quality and was not trusted (p87)
・Whereas the Great Buddha of Nara contains only 1% lead, the Great Buddha of Kamakura contains 10% and was used as a material close to Song coins (p104)
・What Kiyomori was aiming for was to take authority equal to the right to issue currency from the Imperial Court if Song coins became popular and the Taira family could monopolize imports (p112)
・The reason for the change to a monetary economy in about 10 years is that Song coins were spread domestically as copper materials for making Buddhist altar fittings, and since copper itself was highly valuable, Song coins were smoothly trusted as money (p121)
・Complaints and grievances have accumulated to the extent that civil unrest occurred, 1) the advent of the global cold period, 2) the plight of aristocrats and samurai due to the spread of Song Qian (p135)
・The unequal society brought about by Song coins is in a situation where the current yen appreciates; when the value of currency increases, the value of goods decreases, which causes deflation, and the Taira family, which has Song coins, has an advantage (p139)
・Since the value of rice rises when famine occurs, the value of Song coins falls relatively, and hyperinflation occurred all at once due to the famine (p169)
・The reason that lost the most assets due to hyperinflation was that the Heike family was no longer able to do large-scale businesses that employed workers (p170)
・The Battle of Fujikawa, which the Taira family has been good at, was unable to gather people, and the Taira family, which had no standing soldiers, was directly linked to a decline in military power due to a crash in the value of money, and the Battle of Fujikawa was 40,000 versus the Taira clan: 2,000 (p173)
・The Tokaido, which has been a main road since ancient times, passed through Kuwana, Yokkaichi, and Kameyama in Ise, not Sekigahara or Maibara, and was an important point, and Anotsu was famous as one of the “Mitsu-Nanaminato” during the Muromachi period (p184)
・The Taira family defeated the Genji in the Battle of Sunomata River that occurred in 1181/3 after Kiyomori's death (p206)
・In 1183, the Taira family's army defeated Kiso Yoshinaka using the navy, and they won consecutive battles in the Seto Inland Sea (p206)
・The defeat of the Taira family in the Battle of Dannoura was not a change in the tide, but rather Taguchi Naruyoshi's rollover (p207)
・Nationalism centered on land was taken over by the Edo Shogunate and Meiji governments, and land rent (land taxation) was surpassed by liquor tax revenue in 1899, and a land-centered society continued for 700 years (p209)
