I've read some of the more well known ones like Izanagi and Izanami...Amaterasu, Tsukuyomi, Susanoo, and Orochi... I mostly want to know about the Shinto side but Japanese Buddhism legends are good too. I know about Hotei/Budai on that end. Mostly, because I have to remind people that though he is a Buddha he's not Siddhartha Gautama.
"Are there any sort of chief pantheon, a la the Olympians, in Japanese mythology? Who do they consist of?" This question but you don't have to add in the former gods I've listed. Nothing fancy.
