Congratulations on your new Hanabishi Low Sugar Rice Cooker! To ensure you get the best results when cooking rice with it, here's a general guideline on the water-to-rice ratio:

For White Rice:
The typical water-to-rice ratio is 1:1.25 or 1.5 (1 cup of rice to 1.25 or 1.5 cups of water).
For Brown Rice:
The ratio is usually 1:1.5 or 1:1.75 (1 cup of rice to 1.5 or 1.75 cups of water).
For Low Sugar Rice Function:
If you're using the 'Low Sugar' feature, the cooker might adjust the water level slightly to help reduce sugar content. Generally, you would follow the standard water-to-rice ratio but experiment a little to find the right balance for your taste preferences.
Steps for use:

Measure the rice using the cup that comes with the cooker.
Add water based on the ratio above, depending on the type of rice you're using.
If you’re cooking a large batch, you can scale the measurements proportionally.
It’s a good idea to check your rice after cooking. If it’s too soft or sticky, reduce the water slightly next time. If it's a bit hard or undercooked, you may need to add a little more water.
