Try posting sticky notes everywhere with vocab listed for whatever it is posted on. For example, put a sticky note on a chair and write 椅子(いす) for chair. Don't even bother with the English on the note since it should be obvious what the item is by looking at it. That way when you walk around you see them and force yourself to read/memorize them in Japanese. Obviously the vocab will be limited by what you have in your house, but it's better than nothing.
