Before You Use for the First Time


Before you use this product for the first time or after a long period of non-use, please clean the jar following the instructions in “Care & Maintenance” section of this manual.


  • Install Dew Collector on Inner Lid.
  • Without the dew collector, excess moisture forms dews on the inner lid, which drop onto the rice every time you open the lid, making the rice stickier.
  • Put freshly-cooked rice into Jar.
  • Warming the jar interior before you place rice will keep the rice warmer for a longer period.
  • This product is designed for plain rice. If you need to store salty or vinegared food, thoroughly clean the jar after use.
  • Do not add cold rice to the warm rice in the jar or leave a rice scoop inside. It often alters the flavor of the rice inside.
  • Close Lid – Keeping rice warm and fresh.
  • This product will keep the rice inside warm and fresh for five to six hours.
  • Plan to consume the rice within that time period; otherwise the rice may lose its fresh flavor.



  • Store freshly-cooked rice before it gets cold.
  • The secret is to store freshly-cooked rice and as much rice as possible.
    Close the lid tightly.
  • Loose lid may cause the rice inside to dry, discolor and/or smell unpleasantly.
  • Make sure to close the lid tightly every time.
  • In order to preserve the heat inside, keep the lid on and closed tightly all the time except when serving the rice, which should be done quickly.
