It’s always wise to be prepared for emergencies, and even more so in Japan, where there is a high occurrence of natural disasters. If you’re concerned about spending money on things you might not end up using, I have good news to share. You can put together your very own preparedness kit, even on a tight budget!!
The 100 yen shops in Japan carry a number of essential items for emergencies.

These include:
Food (canned food, instant noodles, biscuits, etc) - make sure to get 3 days worth of food per person
Bottled Water - 4 liters of water per person
First Aid Kid (plastic container or water-resistant bag, adhesive bandages, disinfectant, gauze, gloves, tweezers, oral thermometer)
LED Light and Extra Batteries
Portable Toilet (or plastic bags and ties)
Whistle (to call for help)

Aluminium Emergency Blanket

Other items to consider:
