Design Explained –
Our Signature Tune!

Our rice cookers and water boilers are practical. They’re technologically advanced. They’re stylish. And they’re…whimsical!

Until 1999, our appliances used standard beep sounds to indicate when the rice cooker or water boiler had started and finished their settings. We realized that so many appliances existed together in our customers’ kitchens that it was difficult to know which appliance was beeping. So, as part of our tradition of smart design, we programmed our rice cookers and water boilers to play a tune instead of beeping.

And now we’re known for our whimsical, musical and oh-so-familiar “Twinkle, Twinkle, Little Star” tune which plays at the beginning of a setting. And when a course is finished, the lyrical tune of “Amaryllis” plays!


While this feature is definitely one of our more lighthearted and fun ones, there is a solid technological foundation to adding tunes to our appliances. Each appliance needed a microcomputer in the control panel, and that technology was introduced in the late 1990s. Further, microcomputers needed to be programmable, and the manufacturers were able to sequence a series of beeps to make a tune.

We loved it then and we love it now. And so do our fun friends. Just check out this incredibly cute video on our Instagram page:

  1. Please add a happy song to your coffee makers. It would be nice to hear a lovely song at the completion of brewing. I will be the first to buy it.

  2. My friend and I were wondering, if you might share the composer or original performer for Amaryllis?

    It sounds so vaguely familiar, but just googling the title gives us too many hits (and theyre all wrong)

    • Hi Trish, what a great question! According to google: “Amaryllis, a melody from the 1581 Ballet Comique de la Reine, later popularized by Henry Ghys”

      It seems like it was popularized in Japan later on and that’s probably why this tune was selected, but now we’ll have to do more research into the Ballet! Please let us know if you figure out where you may have heard the tune!

  3. I appreciate the thoughtfulness that goes into the design but is there an option to mute the music notification on the water boiler?

    • Hi Berenice! The melody on our water boilers may be turned to silent. Please press and hold the UNLOCK button for more than 3 seconds. If you hear 3 long beeps, press and hold the UNLOCK button again and one long beep should be heard. This would indicate that the water boiler is set to silent!

  4. I have an old cd-wbc40 water heater. It plays music, but the tune is neither “Twinkle, Twinkle, Little Star” nor “Amaryllis”. It sounds like a sped-up version of a specific pop song I remember from the 1960s, but that song itself I recall being based on a piece of classical music. Are there other tunes you use in your water heaters, or am I just wrong about this tune being “Amaryllis”?

    • Hi C, great question! The water boilers have different melody alerts. The melody that plays when the boiling stops is called “Minuet” and when the timer is set it will play “Beautiful Dreamer” Please let us know if you have any more questions!

    • Hi Jan! The NS-RPC10 rice cooker is a conventional rice cooker that doesn’t have an internal micro computer and unfortunately it does not have a signal. Our Micom rice cookers do have melody signals and more cooking settings as well! Please let us know if you have any questions.

  5. Hello! Does the NS-JCC10 play a melody? We used to have a different model that played the melody. Recently it broke. Now sadly this one does not play the melody. Thank you.
