Frequently Asked Questions

This is a selection of the questions which customers most often ask us. A lot of useful information can also be found on the individual product pages (including rice cooking times located on the 'Specifications' Tab), we also have an inbuilt product comparison and have put a pictorial comparison and further information about the differences between the rice cooker models.
Why are you selling Zojirushi rice cookers and water heaters?

We love eating rice (having visited and lived in Asia) and eat it on a daily basis. We were unsatisfied with the rice cookers available to UK residents where the rice cookers often failed to last more than a month of use and spit water everywhere. We researched on the internet as to what rice cookers have the best record of durability and cooking results and found this to be Zojirushi. We bought this product for ourselves...this was 12 years ago and the rice cooker is still going strong and is used everyday. We were so impressed that we decided to source these Zojirushi rice cookers for sale in the UK and Europe so that other people like ourselves can see just how fantastic these cookers are. After using our Zojirushi rice cooker for so long we got a water heater, which has been just as fantastic as the rice cooker!

Why are you selling your own branded rice cooker?

Sakura is Yum Asia's very own rice cooker. Yum Asia has been the home of Zojirushi in the UK and Europe for over 10 years; we have worked with Japanese rice cooking technologies and learned exactly how they work and their best and most useful features. We realised that the cookers did not always fit into everyone’s budget. We also realised that whilst some models ticked all the boxes of what a customer wants from a rice cooker, sometimes certain models didn't tick all those boxes. We therefore spent many months thinking and designing a rice cooker with functions that were most appealing to people that love Asian food with the core emphasis being based around cooking great tasting rice.

Are the products you sell new?

Yes. All the products we sell are brand new in factory wrapping/box. The unit has not been used and has manual and utensils included.

Why choose a Zojirushi?

Zojirushi is the gold standard of many Asian style kitchen appliances but in particular is a market leader for rice cookers and water heaters. The durability of these rice cookers and ability to out-perform all other rice cookers is unbeaten! If you like rice and want the best possible kitchen appliance that will cook it perfectly then this is THE product for you. This rice cooker will go on and on cooking rice for you. The water heaters are the very best model on the market with the benefit of 50-60% energy saving capacity over standard other brand water heaters.


Why choose Sakura by Yum Asia?

We spent a long time thinking about and designing a rice cooker with functions that were most appealing to people that love Asian food with the core emphasis being based around cooking great tasting rice. We decided that the cooker would not only have to function extremely well but look great and have superior reliability comparable to the Zojirushi brand of rice cooker. Every part of the cooker from the display panel, moulded materials, inner bowl, packaging and instruction manual was designed with meticulous detail to ensure that customers would get the very best value for their money.
The factory we chose to manufacture Sakura also manufacturers highly thought of brands like Cuckoo, Cuchen and Tiger.
We have extensively tested Sakura and we conducted blind taste tests with the Yum Asia team and we are all in agreement that Sakura produces rice which is every bit as good as the rice from a Zojirushi!

Do you have a returns policy?

Yes, we have a comprehensive returns policy. Please see this page for details of our returns policy. All the products we sell are provided with Yum Asia's unique 12 months warranty, as products purchased in Asia for sale outside of the country of purchase are not covered by the original Zojirushi warranties. We supply the same 12 months warranty for our own branded products as well.


Are there any reviews of the products you sell?

Yes, we have many happy customers - don't just take our word for it look on each product page for reviews from our customers.

I don't understand the capacity of these rice cookers

he capacity of rice cookers can be confusing, especially because the international standard is to display the capacity in terms of litres of uncooked rice. To make it easy we have put together this table:


 Capacity in cups*

 Capacity in litres/kg

 Number of people

 Translation to cooked rice**

 3 cup

 0.5 litres or 500g

 1-3 people

 1.5 litres or 1.5kg

 5½ cup

 1 litre or 1kg

 1-5 people

 3 litres or 3kg

 8 cup

 1.5 litre or 1.5kg  1-8 people  4.5 litres or 4.5kg

 10 cup

 1.8 litre or 1.8kg

 1-10 people

 5.4 litres or 5.4kg

* 1 cup = 180ml of uncooked rice
**1kg of uncooked rice = 3kg of cooked rice

What else can I cook in these rice cookers?

Essentially Zojirushi rice cookers perform best when used for cooking rice. However, we do have recipes that can be cooked in the rice cookers we sell and the book'The Ultimate Rice Cooker Cookbook' is highly recommended by people who own these rice cookers.

Some models we sell have steaming, cake baking and slow cook functions, which can cook a variety of foods other than rice.

Our own branded Sakura (YUM-EN15) in addition to several rice cooking menu options has useful add-on multi-cooker functions like steaming, cake baking, soup, slow cook, crust (Persian Tahdig), porridge and yoghurt making.

My rice isn't as good as I would like it to be

Take a look at our Tips and Troubleshooting page, where we detail common problems customers encounter.

We have years of rice cooking experience and know our rice, so please feel free to contact us to get advice.

Will these rice cookers and water heaters work on UK and European power supply?

Yes. The rice cookers and water heaters are factory made for UK and European 220-240v, 50hz power supply. The unit comes fitted with a British 3-pin rectangular blade plug. All our electrical products are compatible with European and Australian power (or any country with 220-240v power) and just need an adapter plug. Please note that models imported from the US and Japan run on a different power supply (110v) and WILL NOT work on UK, European and Australian power.

Where are these products made?

The Zojirushi products we sell are made in dedicated Zojirushi factories in China (NS-LAQ05, NL-BGQ05, NS-TSQ10, NS-TSQ18, CV-CSQ30) or Japan (NS-YSQ10, NS-YSQ18, NL-AAQ10, NL-AAQ18, CV-DSQ40). Only Zojirushi products are made in these factories; Zojirushi manufacturing standards are extremely high and the factories have a reputation of excellence with build quality and detailed quality control.


Our Sakura (YUM-EN15) own brand is manufactured in dedicated Chinese factories which also make premium brand rice cookers like Cuckoo, Cuchen and Tiger. Our factory conforms to the highest international standards and has comprehensive quality control and manufacturing  procedures which we have had independently inspected.


Can't I just buy a Zojirushi or other rice cooker from USA and import it?

No. USA units are not compatible with UK, European and Australian power supply (they are 110v and 60Hz) and you would need to purchase a bulky and expensive transformer to convert the voltage so you could use it. Transformers for stepping up voltage take up a lot of electricty when converting voltage, are bulky and don't convert the cyclical electricity frequency of an appliance (ie they don't convert from 60Hz to 50Hz). We have had several customers who have tried to use US rice cookers with a voltage converter and they do not work or broke within 6 months.

Are these products CE Marked for European and UK use?

Yes, all the Zojirushi products and the Yum Asia branded products we sell have the CE Mark applied. We hold a EU Declaration of Conformity for all these products showing conformance to the relevant UK and European safety directives. 

How do Fuzzy Logic Micom rice cookers work?

Fuzzy Logic Micom rice cookers are sophisticated machines, see our page, how rice cookers work. Briefly, the computer chip is the brains of the unit, it makes the cooking of rice foolproof. Instead of the cooker simply switching on and off reacting to temperature, the rice cooker makes small adjustments in temperature and cooking time according to what the thermal sensor senses. This means the rice is steamed rather than boiled and it therefore gives a completely different taste and texture to rice cooked in a saucepan on a stove. It’s this steaming process which takes the time to cook the rice.

Does it cost a lot to keep a Zojirushi water heater on all the time?

No. A lot of the energy in a traditional kettle is wasted because of poor insulation, as water is converted to steam before it switches off. There is also excess water which is heated and left in the kettle but not used - most people overfill their kettles. The inner pot of these water heaters are insulated therefore the energy goes into the water, no steam is produced and very little energy is needed to keep it warm. It is estimated that maintaining the water temperature costs less than 7 pence per day (depending on electricity tariffs). Remember that each time you boil a kettle it costs you each time it is boiled - you are probably heating more water than you need too every time you boil your ordinary kettle and then letting it cool. These Zojirushi water heaters retain most of the energy used, therefore saving you money to use on other things!

Why don't you stock Zojirushi Induction Heating (IH) models?

Although there are quite a few IH and pressure models for sale which are available for 110v power there is only one 220-240v IH and one 220-240v IH plus pressure equivalent available. After looking at the features of the Induction Heating (IH) models, we believe that it does not offer anything substantially different to the models we currently stock to justify the high price of these cookers, so we have decided at this moment in time not to stock this model.


To give you a little bit of background to our decision, our suppliers have demonstrated both the IH model and the models that we stock, we tasted rice from each model and we honestly couldn't tell the difference between the models. The only difference in the rice cookers we could see was that the IH model has a 'regular, softer, harder' setting for the texture of white rice, which is easy to replicate by adjusting water levels and the GABA brown rice setting which the YSQ10 already has. Other than this, the induction heating method is slightly different electronics (ie the heating element is slightly different).


The IH models actually do their best work with plain rice, they don't cook rice any better than the fuzzy logic models we supply and they also don't cook oatmeal porridge, a feature a lot of our customers are interested in. Induction heating models are still quite expensive (the IH model is around £100 more than the YSQ10 and the IH plus pressure is around £250 more). There are also some issues with power supply and the IH models – what we mean by this is that the electrical frequency cycle has to be exactly right for IH models to work as they use magnets to heat the inner bowl, it’s extremely important that the frequency of the machine and the power supply match.


Most importantly, the IH models for 220-240v power also haven’t passed any CE safety tests for use in the UK or Europe so it therefore cannot be legally supplied within the UK or Europe. Knowing what we do about the way IH models work, we do not think they would pass the CE safety tests either.  The only Zojirushi rice cookers we sell are the latest fuzzy logic models which are here

How can I tell the difference between fuzzy logic and Induction Heating (IH) rice cookers?

Some Chinese-made rice cookers claim to be IH models but they are actually fuzzy logic rice cookers. All fuzzy logic rice cookers have a round metal heating element inside the rice cooker which the inner bowl sits on top of (like a disc with a pressure sensor in the middle). Induction heating models do not have this heating element as they cook by using a magnetic field.


The inside of an Induction Heating model is completely smooth with just a pressure sensor in the middle of the bowl and a pressure line around half way up the side of the inside of the machine to help the magnetic field use the bowl as the heating element. Although the fuzzy logic rice cooker inner bowls are very heavy duty (aluminium coated stainless steel with an outer coating of non-stick), Induction Heating model bowls are much heavier as they are made from different materials (usually aluminium coated stainless steel which is then coated with either copper or a ceramic material as well as a non-stick outer coating) as they need to conduct the heat in a completely different way. It is easy to tell the difference between the two types of rice cooker once you know what you are looking for! See our page how rice cookers work for more details. Induction Heating models use a lot more power than fuzzy logic models - for example, a 5½ cup fuzzy logic is a 570 - 610W machine whereas the same size Induction model is typically 1200W or more.

As Yum Asia is a small company, we are not registered for VAT and are therefore unable to discount our prices by the current VAT amount nor can we provide any kind of VAT invoice.


Are your products shipped from the UK?

Yes. We send ALL products from within the UK which means that there are no import or customs fees if you are based in the UK or EU. These Customs fees when importing into the UK or EU can sometimes be up to 50% of the value of the item as Customs fees and Import Duty are calculated on the value of the item and shipping combined. Best of all, it's delivered fast so no waiting for weeks for delivery!


When I check out I get a message saying 'Warning: No Shipping options are available. Please contact us for assistance!'. What does this mean?

You will receive this message if you are trying to check out with a delivery address in a country we do not ship to - see our delivery information page for more details.

We only provide warranty services and after-sales spare parts service for the unit which we have recorded as you purchasing. 

For more information, please see

Can I put the inner bowl and inner lid in the dishwasher?

No, never put the inner bowl or inner lid into a dishwasher. You can soak the inner bowl and inner lid if necessary and then wash with a sponge/soft cloth. This is because the washing cycle on a dishwasher is just too harsh and even being put in a dishwasher just once can be enough to destroy the coating on the inner bowl and inner lid.

Do you supply spare parts for the products you sell?

Yes, we supply spare parts for the Zojirushi products we sell to customers who have previously purchased from us. These spare parts usually need to be ordered in advance and take approximately 6-8 weeks to come in stock. Our prices for spare parts include shipping and the spare parts we supply can be found here. We also supply spare parts for Sakura (YUM-EN15) and you can find a list of spare part names in the manual.
