Slice the kabocha into pieces, put it in a heatproof dish, wrap, and boil in the microwave. Mash with a fork when it's done.
Thinly slice the sweet onion, soak it in water, then squeeze out the moisture. Mix all the ingredients together in a bowl, and season with salt and pepper.

Story Behind this Recipe
I like kabocha salad, and made it with sweet onions.
In Step 1, add a little water when boiling the kabocha for a tasty finish. Don't soak the onion in water for too long. It's nice if you add canned tuna too. You can use shio-koji instead of salt. It's still tasty even if you don't add onion. Homemade Mayonnaise Recipe ID: 1743416.
