I like to slice the kabocha and in half and roast it at 350º cut-side down on a parchment lined baking sheet until I can pierce the skin with a knife, which in my oven is about 30 minutes. I store any leftover squash in the refrigerator and slice the amount I need as I go. once roasted it's easy to scoop the seeds out, and then scoop the squash out of the skin.
Extra roasted kabocha is great cold with a sauce made with tahini, tamari, maple, and a bit of miso diluted in hot water.
