That big book in the glove box hidden underneath all of the napkins has this convenient drawing in it. It doesn't look like anything was intended to go there in the North American market.
You gave me enough information to start a search. Toyota offered an Emergency Assistance Kit and a First Aid Kit that were optional items, usually purchased directly from the dealer as an afterpurchase item or at the time of purchase. Looking at the images of these items, it seems that they'd fit the spaces highlighted in my original post.
These kits fit many Toyota models over many years, and may still be purchased from Toyota.
