Ok, think I just accidentally finished the crossword.
38-down シリメツレツ - it’s a four-character phrase, so I confess I cheated. Probably wan’t going to get it otherwise. 
32-across イビツ I think
36-across オリ
35-down チシオ
Makes 30-across モチ, and I confess I thought of that a while ago, but wasn’t very sure.

Think maybe we’ll leave it at that until I get back from my trip.
