How To Cook Japanese Rice In A Rice Cooker

If you love Japanese cuisine, learning how to cook Japanese rice in a rice cooker will make things easier for you in the kitchen.  

Rice, like in many other countries, is a staple in Japan. Rice has been cultivated for thousands of years in Japan and the Japanese eat rice almost every day, sometimes even in all three meals! 

Japanese rice is a short-grain variety of rice with a sticky texture. To get that perfect consistency of sticky rice, the trick is to get the perfect water to rice ratio when you cook the rice. It’s super easy to do with a rice cooker as the rice cooker has measurements on it and you can measure the level of water as you pour it in the rice cooker. 

Keep on reading to find out how to cook Japanese rice in a rice cooker with perfect Japanese rice to water ratio in a rice cooker.

How To Cook Japanese Rice In A Rice Cooker 

When cooked properly. Japanese rice will have a sticky texture with enough moisture that it goes down your throat easily. But if the water ratio is even slightly off, you’ll end up with really dry rice.

If you check online, you’ll find the most ‘how to cook Japanese rice’ blogs and articles say that the water to short-grain rice ratio should be 1:1, this is where you go wrong (don’t worry, it’s a common mistake and I’ve done this myself before too.) 

“The water to Japanese short grain ratio is 1:1.1 or 1:1.2’’

This basically means that you need to add 10% to 20% more water than Japanese rice, that is, for 1 rice cooker cup (180ml), you have to add 200 ml of water! It’s just that simple. 

This way you know your rice has enough moisture to not go completely dry. 

But if you still want to go with the 1:1 rice to water ratio then soak the Japanese rice in a separate water for about 30 minutes before cooking, drain it well, and then add the measured amount of water for 1:1 rice to water ratio. 

The problem is that most recipes for how to cook Japanese rice in a rice cooker miss out on this step. And your rice is deprived of that extra 10-20% of moisture because of which it comes out dry.

How much water do you use when cooking Japanese rice in a rice cooker?

When cooking Japanese rice in a rice cooker follow the rule of 1:1.1 or 1:1.2 rice to water ratio.

So if…

One cup of Japanese rice is 180 ml then use 200 ml of water.

2 cups of Japanese rice is 360 ml then use 400 ml of water

3 cups of Japanese rice is 540 ml then use  600 ml of water

4 cups of Japanese rice is 720 ml then use 800 ml of water 

5 cups of Japanese rice is 900 ml then use 1000 ml of water. 

Just follow this calculation to get the perfect water to rice ratio when cooking Japanese rice in a rice cooker. 

Formula: If one rice cooker cup = 180 ml 

180ml x no. of rice cooker cups of rice x 1.1 (or 1.2) = amount of water to add in ml 

Say, for example, you want to cook 5 and half cups of Japanese rice then: 

180ml x 5.5 x 1.1 (or 1.2) = 1,089 ml (or 1,188) ml of water should be added to the rice cooker.

If you don’t have the patience to measure the water to the T then just add a little more water than the amount of rice you’ve added to the rice cooker. So if you put 3 cups of Japanese rice then add 3 cups of water plus a little more water to the rice cooker. 

Japanese Rice Secret Tip: Do Not Skip The Soaking

Unlike other varieties of rice, it’s important to soak Japanese short-grain rice in water for at least 20-30 minutes so that short rice grain absorbs enough moisture to its core.

My favorite rice cooker is the Zojirushi Japanese rice cooker and warmer. It can cook up to 5 and a half cups of uncooked Japanese rice. It does take quite a bit of space in your kitchen counter but that’s okay because the benefits it offers will make your life so much easier.

It has an automatic ‘keep warm’ feature and extended ‘keep warm’ feature so once your rice is cooked it will stay warm until you decide to serve it. You can steam veggies or even bake a cake!

How to reheat Japanese rice in a microwave

Transfer the rice to a microwave safe dish. Sprinkle some about 2 tablespoons of water over the rice. (A little more water if there’s more rice). Cover the bowl with the rice with a damp paper towel and turn on the microwave. Let it heat for about 20 seconds per cup of rice or until it is thoroughly hot. 

If you’re heating a large amount of rice then you may have to pause the heating in the middle and stir the rice and stick it back in the microwave for even heating.

Transfer the rice in a pot. The pot you choose to reheat rice on the stovetop shouldn’t be too deep so you stir it easily.
