Cut all the vegetables into small pieces. (You don't have to peel the skin of kabocha)
Heat the oil until it's about 375F.
Deep fry vegetables until they're cooked (usually about a few minutes). Once they're done, set them aside on a cooling rack or paper towels.
For Broth 1, combine all the ingredients together in a pot and let it boil.
Add the vegetables into the broth mixture and let it simmer for about 5 minutes.
Transfer everything into a bowl or a container and let it cool. (I usually leave it in the fridge for a couple of hours.)
For broth 2, combine ponzu and sugar in a bowl or a container, and add vegetables. Let it cool.
