The most famous Japanese brown sugar is made in Okinawa and is simply made of sugar cane.

We use brown sugar and white sugar for different usages. According to Traditional Chinese Medicine (TCM), brown sugar warms your spleen and stomach, nourishes blood, and improves blood circulation, whereas white sugar moistens your lungs and helps you reduce phlegm. 
Brown sugar is particularly beneficial for people with blood deficiency and blood stasis constitutions. 
However, If you have phlegm-dampness symptoms, try to reduce the amount of sugar for cooking, adding to drinks and sweets because both types of sugar have the property of moistening your body. 

"Blood Deficiency" might sound weird to you. If you would like to know about "Blood" and "Blood Deficiency" in TCM, visit this website.
