Buying a Rice Cooker from Japan? What Zojirushi's Japanese Manual Says About 100V and the Warranty

Short answerFor use in the US, buy the US model. Zojirushi's own Japanese manual says its Japan-market cookers must not be used on anything other than 100V, and the warranty is valid only in Japan. The 120V US models below are the safe way to get the same heating types.

01Why people look at Japan-market models

Zojirushi's Japanese lineup is larger than what it sells in the US. Its Japanese site lists pressure IH lines such as Enbu-daki ("dancing flame") that do not appear on Zojirushi's US online store (we checked on October 28, 2026), so it is natural to wonder whether an imported one is worth it.

We read Zojirushi's Japanese pages and manual for a current Japan-market pressure IH model, the NW-BC10/18, so you do not have to. Here is what the maker itself says.

大粒でふっくら甘みのあるごはんを炊き上げる「炎舞炊き」の最高峰モデル。

In EnglishThe top model of the "Enbu-daki" (dancing flame) line, cooking rice with large, plump, sweet grains. Zojirushi Japan lists it as the NX-AB10/18.

Quotes are copied word for word from the maker's own manual or website, many of them published only in Japanese. The English lines are our translation. Details differ by model and year, so check the manual for the exact model you buy.

02What the Japanese manual says about voltage and warranty

Two lines decide it. The safety section says not to use the cooker on anything other than 100V AC, and the warranty page says the warranty is valid only in Japan. Japan's outlets are 100V while the US models on this page are rated 120 volts, so a Japan-market cooker would need a step-down transformer, and a fault would not be covered either way.

交流100V以外では使用しない

In EnglishDo not use on anything other than 100V AC.

03The same manual's list of things not to cook

The Japanese manual also lists dishes you must not make in the cooker, because they can block the steam vent. These are worth knowing before you plan to use any pressure rice cooker as a multi-cooker. Check your own US manual for the exact list for your model.

●のり状になるカレーやシチューのルーなどの料理●多量の油を入れる料理●ジャムなどの泡立つ料理

In EnglishListed under dishes you must not cook: curry or stew made with thickening roux, dishes with a lot of oil, and dishes that foam, such as jam.

04US models with the same heating types

If what you want is pressure IH, the NW-JEC10 is Zojirushi's US pressure IH model. For induction heating without pressure there is the NP-HCC10, and for a plain Micom cooker the NS-ZCC10. All three are rated 120 volts on Zojirushi's US store. Our pressure guide and IH vs Micom guide explain the differences.
