| Research Abstract |
1.It is likely that the naming of Nihon-kai was written on the Ignacio Moreira's map of Japan, and that the map of Japan was made on the basis of the geographical knowledge that the Sea of Japan was surrounded by the Eurasian Continent and the Japanese Islands.
2.Matteo Ricci got this geographical knowledge from him and made the world map Kon'yo-bankoku-zenzu (1602), the oldest extant map which the naming of Nihon-kai was written on.
3.The formation of the naming of Nihon-kai was closely linked with this geographical knowledge.
4.The Moreira-type maps of Japan like the C.Blancus's map of Japan (1617) playd an important role in the spread of the naming of Nihon-kai in Europe.
5.The Gyoki-type maps of Japan, Japanese traditional maps of Japan, did not play an important role in the formation of this geographical knowledge.
6.Some islands depicted on the Gyoki-type maps of Japan were closely linked with the structure of the maps. Therefore, they kept on being depicted as long as the structure was maintained, even after the new geographical knowledge about them was acquired.
7.The original source of a mysterious island Etsu-chu-go on the Ishikawa Ryusen's world map Bankoku-sokaizu was Kon'yo-bankoku-zenzu, the immediate, the world maps included in Hoyo-shoryaku and so forth which were derived from it
8.Almost two hundred maps that the naming of this sea were written on were collected systematically.
