A lot of JP homes have a, i wouldn't say nook, but like a hole in the floor to store those emergency rations. also, in japan, the canned goods all have ring pulls. who the hell gonna look for a can opener during emergencies? I live in an apartment so those don't come with those emergency holes like the homes where you can store it. the council will tell you to keep them all in an emergency bag (they always give an easy to follow list) and store it in some place where it is easier to reach like in the closet. you also need to store enough for a minimum 3 days but i got a week going and i cycle them every 3 months
