In the Prefatory Remarks to Aizawa Yasushi‘s 1825 New Theses (新論) we find an interesting little gloss on the relationship of the “Divine Realm” of Japan and the Western world:
The earth lies amid the heavenly firmament, is round in shape, and has no edges. All things exist as nature dictates. Thus, our Divine Realm is at the top of the world. Though not a very large country, it reigns over the Four Quarters because its Imperial Line has never known dynastic change. The Western barbarians represent the thighs, legs, and feet of the universe. This is why they sail hither and yon, indifferent to the distances involved. Moreover, the country they call America is located at the rear end of the world, so its inhabitants are stupid and incompetent. All of this is as nature dictates.
