Even in Asia, I'm sure you've heard of Minute Rice which is a brand name of instant rice. Instant rice is rice that's already been cooked and then had the water removed (dehydrated). It tastes pretty bad/bland unless you're someone who was raised on it. A person is meant to add boiling water to it, stir and cover (without cooking it) and it's supposed to be reconstituted in a minute or less.
Since it's already cooked, the boiling water is only meant to make it hot for eating. Cold water would also work but take longer to rehydrate.
You can make instant rice yourself, dehydrate it and properly store it for emergencies. You'd need to make sure it's throughly dry before storage and that your containers are completely water and air tight. A glass container with a snug lid would suit but I'm not sure if glass containers might not be broken during a catastrophic event. Metal or very good quality plastic would be safer.
I'd not plan on storing your instant rice longer than a year (or less) but then most food stored as emergency supplies need to be cycled yearly. Since instant rice doesn't have the best flavour, I'd use the old supplies to make congee where long cooking is best for it anyway. This site explains how to make your own instant rice.
I don't have a dehydator but I use my oven to dry herbs. The oven setting doesn't go below 200° F (94-5° C) but I found that using a 100 watt incandescent bulb instead of the oven light bulb and leaving it on brought it close to the temperature a dehydator gives. I'd stir the rice around every few hours to make sure it dried evenly.
This is about the best solution to eating rice without any means of cooking it. Maybe not ideal but enough to provide your needs in an emergency. Instant rice only takes up a little more space than dried raw rice. You might even look into getting some of those food-safe silica gel packs for food products to absorb any moisture to be extra safe and add them to each container in storage.
Edited for further cautions
It doesn't matter how much food you have to eat if your water supply isn't safe. A suggeston I read years back given by the UN has stuck with me so I did some digging to find it in order to provide a credible reference. You can sterilize your emergency water supplies without boiling or treating it with bleach or iodine as long as it's sunny.
Since the information is I'm a PDF file, I'll give the link but summarize it here. Essentially, the UV rays from sunlight will kill any pathogens present. If contaminated with chemicals from a spill, I won't work, of course. Containers used need to be clean and be clear plastic. Used pop or water bottles work well. Please look over the link given to find the simple steps needed. In many places in the world, safe water is hard to come by and even clean water can be germ-laden. This method ensures almost anyone can have access to safe water. In extremely dire circumstances, muddy water could be filtreed through cloth a few times and let stand to take the clear water off and then sterilized. Water can mean the difference between life and death. One should always be prepared for the worse case scenario.
