Measure rice while leveling o
Measuring cup
provided
If you shake the measuring cup,
an excessive amount of rice will
be put in the cup.
Do not wash rice in hot water
Do not wash rice too long
Washing it in hot water or taking too long will
make it smell of bran.
Wash rice gently so as not to break it
To wash the rice, gently rub the rice grains against
one another with your hands. (Broken rice grains
can cause mushy rice.)
Adjust the amount of water as necessary
For harder rice Put less water against the
scale.
For softer rice
Put more water against
the scale.
For freshly-harvested
rice
Put less water against the
scale.
For whole rice Put the amount of water
on the scale.
For old rice
During the rainy
season and in summer
Put more water against
the scale.
Adjust the amount of water according to cases, as
it varies depending on the type and area where the
rice was harvested, and how it was stored.
Loosen rice immediately after it has
been cooked
While holding the inner pot with a
dry cloth or mitten, cut the whole
rice into four equal portions and
turn them over one by one to
loosen them.
By doing so, coagulation and
stickiness of the rice can be avoided.
Do not keep the rice warm too long
Instead of keeping rice warm for a long time or
keeping small volume of rice or mixed rice warm, it
is recoomended to wrap the rice in plastic wrap
and store it in the freezer.
Tips for cooking tasty rice
About rice
• It is recommended to purchase rice which has been
polished as recently as possible in such volume
that you can eat up within two weeks to a month.
• Store rice in a sealed container in a dark, cold place.
Do not leave rice in a sieve basket after
washing it
Avoid leaving rice
in a sieve basket
after washing it.
Water that is not appropriate for cooking
It causes drying out
or hardening of rice.
（ ）
It causes a yellow
discoloration or mushy rice.
（）
Water temperature of 30°C or less
It is recommended to use cold
water when you cook rice by
setting the timer in hot weather.
A high water temperature
causes poorly-cooked rice
and/or bad odors.
（）
Please clean the rice cooker as soon as it
has cooled after use
After washing the inner lid
and steam vent, wipe them
with a clean dishcloth to
remove water.
If the rice cooker is
left dirty, it can cause
bad odors.
Do not leave rice in
the pot after turning
off Keep Warm mode.
(It may cause a bad
odor.)
（）
The rice grains
crack and
become mushy
when cooked.
Use cold water
in summer.

Cooking courses
Select the cooking course appropriate to your choice and water level scale
on the inner pot.
• Select your preferred cooking course for white or pre-washed rice. (See page 18.)
• See page 19 for "Tips for cooking rice".
★: The minimum and maximum rice-cooking volumes differ from the respective water level scales on the inner pot.
* : For <Washed> rice, the cooking time is approximately 5 minutes longer. (The displayed cooking time is also 5
minutes longer.)
• Actual cooking time may vary by about 10 minutes depending on the volume of rice, water temperature, amount of
water, etc. Use the cooking time as a guide. (The cooking times are based on the following conditions: Voltage of
220V, a room temperature/water temperature of 23°C, and the standard amount of water.)
• When you want to cook softer congee, reduce the amount of rice or increase the amount of water. Be sure not to add
water exceeding the maximum water level scale for “Congee” on the inner pot.

Using different cooking courses
For <White> or <Washed> rice
Select your preferred cooking course.
■When you want the rice to taste really good
Delicious The cooker cooks rice to bring out the intrinsic deliciousness of the rice.
After trying rice Delicious, try another course according to your prefferred hard or sticky rice texture.
Hard : When you want the rice to be nice and firm.
Sticky : When you want to eat sticky and soft rice.
When you cannot cook rice the way you like
If it is soft →Reduce water or select <Hard> for cooking.
If it is hard →Increase water or select the <Sticky> cooking course. Soak rice before cooking it.
■If you are in a hurry and want the rice to be cooked soon
Quick There is time to make the rest of the meal when the rice is cooking.
• Since this cooking course prioritizes cooking speed, rice may end up being a little bit hard, or slightly watery. To
prevent this, soak rice in water in advance, or steam it longer without opening the lid after the cooker has
entered the Keep Warm mode.
• The following kinds of rice cannot be cooked using <Quick> course.
Mixed rice / brown rice / congee / sweet rice / any other rice apart from white rice and pre-washed rice / Rice
with mixed grains
■Regular cooking method
This is the default cooking course.
If it is not to your liking, try the Delicious, Hard or Sticky course.

When mixed with white rice →<Grains / Regular>
When mixed with brown rice →<Brown / Regular>
When mixed into white rice congee →<White / Congee>
When mixed into brown rice congee →<Brown / Congee>
Pre-washed rice (Processed rice that does not require pre-washing)
• When water is poured in, stir the rice from the bottom to mix the rice and water together. If the water becomes cloudy,
drain the water and wash it again 1 or 2 times. (This prevents the rice from cooking badly, scorching and boiling over.)
• Add water according to the "Pre-Washed rice" water level scale, and select the <Washed> course .
Mixed rice / sweet rice
➡
For cooking "Mixed rice with ingredients" and "Sweet rice with red beans" see pages 26 and 27.
• For tips on cooking these types of rice, see "When you add ingredients and seasonings" on page 26.
• When making sweet rice, if only sweet rice is used, the cooked rice becomes too soft, so add 1 cup of standard rice
to every 2 cups of sweet rice. When cooking only sweet rice, adjust water volume to slightly below the water level
scale of "Sweet rice".
Rice with mixed grains
• Use the <Grains / Regular> course.
Up to 3 cups (1.0 L type) / 5 cups (1.8 L type) can be cooked.
•
For the amount of mixed grains to be added to rice, follow the
instructions printed on the package of the mixed grains. (If
there are no instructions on the package, add the mixed grains
at about 10% of the amount of the white rice to be cooked.)
You may also cook pre-washed rice.
• Wash white rice quickly until water becomes clear, add water
to the appropriate water level scale by the number of cups for
"White rice"; or by the number of cups for "Pre-washed rice"
for pre-washed rice.
• When cooking this type of rice the steam vent may become
dirty, so be sure to clean the inside of it.
If you are using grains that float in water, soak the rice
and grains for 2 to 3 hours, and only cook the rice when
the grains have sunk.
(Floating grains may block the steam vent, causing steam
leaks, or the deformation or damage of the cooker.)
Congee / brown rice congee
• Use the <Congee> course.
• Add salt and other seasonings after the congee is cooked. (If seasonings are added from the beginning, the rice may not
be cooked well.)
•
Depending on the type of rice, the water temperature, and how the rice was washed, water droplets may come out of the steam vent.
• Congee cannot be made from cooked rice.
When making traditional Japanese congee that contains 7 herbs of spring, do not mix the greens from the
start. (The steam vent may become blocked, causing steam leaks, burns and damage.)
Boil the greens, and add them after the congee is cooked.
Brown rice
• Use the <Brown / Delicious> or <Brown / Regular>
course.
• <Brown>takes longer to cook than white rice. The
rice can be cooked immediately after it has been
washed.
• When cooking brown rice mixed with white rice,
soak the brown rice for 2 hours prior to cooking
and select the <White / Sticky> course.
Germinated brown rice
• Use the <Grains / Regular> course.
• It is recommended to cook germinated brown rice
with white rice in a ratio of 1 to 2. You may also
cook germinated rice only.
Tips for cooking rice
Try cooking rice, and then
adjust the amount of water.
See page 16 for "Cooking courses".
• Since congee, brown rice, multi-grain rice and soup is
high in water content, ensure to use the dedicated
cooking courses (not <Quick> course, and so on).
(Otherwise, the cooker may boil over or you may get burned.)
•
Do not increase the amount of water too much.
(The allowable additional amount of water is up to 2 mm over
the regular water level scale as a guide.)
Partially milled rice
• Use the <Grains / Regular> course.
•
Wash partially milled rice thoroughly to remove its brans.
• Depending on the rice milling degree, the milled brown
rice may be called differently; "30%-milled rice" (similar to
brown rice), and "70%-milled rice" (similar to white rice).
