A central dogma of the Japanese history is that, throughout the history, there was absolutely no other dynasty or kingdom than the dynasty of the Imperial House of Japan (Yamato dynasty) which continues to exist since some 1500∼2000 years ago. Although much inconsistency has been noted between this dogma and accumulated records of Chinese historical documents on ancient Japan, almost all the Japanese historians have not taken such inconsistency seriously and even attributed it to mistakes or confusion of the Chinese historians who wrote the documents. But, one historian, Takehiko Furuta, who fully believes in the Chinese records, analyzed them recently in a very logical and even scientific manner and reached a surprising conclusion that there was a dynasty in northern Kyushu (Kyushu dynasty) and it was always this dynasty that appeared in the Chinese old records until 648 A.D., whereas the Yamato dynasty which started as a branch of the Kyushu dynasty finally overcame the Kyushu dynasty around 700 A.D.This new theory seems to be supported by many archaeological discoveries in and around the Fukuoka area, one of the most notable examples of which is the Gold Seal that appears in the Symposium poster. These remind us of the famous story that Heinrich Scliemann who believed in Homer’sThe Iliadas real finally succeeded in excavating the ruins of Troy.
