The concept of plane figures and solids in mathematics in Japan is different from that in other countries. It is unique in that it captures solid objects with surfaces, and is also related to the uniqueness of origami play and packaging. In other words, the way we think about spatial understanding is different from that of other countries. Perhaps the sense of time is also different and related to punctuality.
From the viewpoint of language, Levi-Strauss' concept about Japan is quite convincing. The Jananese language doesn't have a constant first person singular pronoun. It changes according to the situation or circumstances--"watakushi", "watashi", "atashi", "uchi", "washi", "boku", "ore", "jibun", etc. Not only English 'I' but also other European languages have their only first person singular pronouns whether the person is female or male, young or old, of high social status or not. For the Japanese, the starting point is not "Self", but his/her circumstances they are in.
Yeah, Japanese myth has many similar episodes to other culture's myth. For example, there's an episode that the husband goes to hades to bring back his dead wife and he is told that he should never look back before he reaches over the ground. This is similar to the Orpheus story in Greek myth and also to the Lot's wife story in the old testament.
