Zojirushi NP-HBC10-18 vs NP-GBC05

If you are sold on getting one of the Zojirushi induction heating rice cookers and have narrowed your list down to two models, Zojirushi NP-HBC10/18 vs NP-GBC05, this comparison is for you.

To an average consumer, it’s often hard to differentiate between two product models such as this set. They are so similar in features, yet they are somewhat different. But figuring out what makes them different is not an easy task.


The first difference is quite obvious in capacity size. The NP-HBC 10 and 18 have capacity sizes of 5.5 cups and 10 cups (uncooked rice) respectively. The NP-GBC05 on the other hand, only has 3 cups, which is a good size for singles and small families. For mid-size families, the 5.5 cups would work out well and so does the 10 cup for large families.


Due to the capacity size, the two NP-HBC10/18 rice cookers are bigger than the NP-GBC05. Please see the exact dimension sizes in the attached comparison chart.


The Zojirushi HBC models are stainless steel in color vs the stainless brown in NP-GBC05 rice cooker.

Keep Warm/Extended Keep Warm

The Zojirushi Induction NP-HBC model has “Extended Keep Warm” feature after “Keep Warm” runs out of 12 hours. In all honesty, how often would you keep your cooked rice in the cooker after 12 hours anyway? So this feature is very marginal at best. The NP-GBC doesn’t have this feature.

Menu Options

White Rice Texture

The Zojirushi NP-HBC10/18 rice cookers have a few menu options that are absent in NP-GBC model. These options are “softer” or “harder” for the white rice. So you like your white rice to be a little bit firmer that the default white rice texture setting, you can “fine-tune” the texture using this option.

Sweet Rice

The second option in NP-HBC is the sweet rice setting. For those of you who don’t know much about sweet rice, it’s also called glutinous rice. It’s sticky in texture and often used to make dessert in the Oriental culture such as the Sticky Rice in Coconut Cream Sauce with Fresh Mango. This is a very popular dessert in Thailand and other Asian countries. The NP-GBC05 doesn’t have this option, but it doesn’t mean you can’t cook sticky rice in your rice cooker at all if you know how to adjust the rice and water ratio.

Rinse-Free Rice

One menu setting that the NP-GBC05 rice cooker has is the rinse-free rice which is not available in the NP-HBCs. Rinse-free rice is milled through a new technology developed in Japan. During the milling process, the excessive bran and starch are eliminated resulting in smoother texture in cooked rice.

All Zojirushi rice cookers are capable of cooking this type of rice as long as you reduce the measured dry rice by a heaping teaspoon. In the case of the NP-GBC05, it has the specific setting for it. So you don’t have to do anything special as the rice cooker will adjust the cooking time and temperature automatically. Please be aware that there is a special green measuring cup that comes with this type of rice cookers. Remember to use it instead of the white measuring cup.

Mixed Rice

Another miner difference is that HP-GBC05 doesn’t have a setting for mixed rice. Instead, you’ll have to use the white rice setting.

I often wonder if Japanese has made such a big deal of the art and science of rice-cooking. Then again, who am I to judge as long as we all reap the benefits from their innovation.

Electricity Consumptions

NP-HBC10, 1230 watts per cooking hour and 29 watts per “keep warm” hour

NP-HBC18, 1350 watts per cooking hour and 38 watts per “keep warm” hour

NP-GBC05, 700 watts per cooking hour and 25 watts per “keep warm” hour


The NP-HBC rice cookers are more expensive ($30 to $35 more at the time of this review on Amazon) not so much because of the extra features, but because of the capacity size.

Final Thought

If I were you, it’s more important to decide which size you should get first for you or your family. The NP-HBC is a newer model so it has a few features that are not in the HP-GBC05 rice cooker. I don’t think any of the added features are that significant. No matter what you decide, it’s hard to make a wrong decision given that Zojirushi produces one of the best rice cookers in the world.

Zojirushi NP-HBC10/18 vs NP-GBC05 Rice Cookers

    Hey there,

    Just found this writeup. Thanks for the info.

    I have the NP-GBC05 and just figured out that it doesn’t have a setting for sticky rice. I emailed Zojirushi and they said “I am very sorry to inform you that the NP-GBC05 model rice cooker doesn’t have the setting for sticky rice.

    We do not recommend cooking any other types of grains or ingredients other than white rice (or brown rice).

    We have not tested other types grains in our rice cookers and they may overflow and damage the unit or discolor the inner cooking pan. They are primarily for cooking rice only.”

    So now I am trying to figure out what to do…

    You mention in your review that “The NP-GBC05 doesn’t have this option, but it doesn’t mean you can’t cook sticky rice in your rice cooker at all if you know how to adjust the rice and water ratio.”

    So have you figured out how to do this? What setting and what ratio are needed?

    Thanks in advance!

    – Jon

      Thanks for reaching out. I would soak the sticky rice overnight and rinse it until the water is clear before cooking. Use the white rice water line in your rice cooker. The ratio is 1 cup of sticky rice to 2 cups of water if you are curious. This is just a general guideline as the age of crops will make a difference, too. Newer crops require slightly less water and the opposite is true for the older crops. Plus it depends your preferred doneness and what dish you are trying to make. If I were you, I would test 1 cup of rice first to get the consistency you like, then do more. Hope this helps.
