Sugar
The most popular sugar you see in the Japanese supermarket is Johakuto(上白糖)-White sugar. However, this is slightly different from the white sugar that is sold as caster sugar in US and UK. If you are looking for caster sugar, you need to buy Guranyuto(グラニュー糖)
Here are the main varieties you may see in the Japanese Supermarket:
I personally use kibisato (cane sugar) for all my cooking. As for baking, I would use Granyuto (caster sugar) in general just to keep the color. Kibisato is more expensive than Johakuto, but it contains minerals without sacrificing its taste. For your info, Sugar beets are mainly produced in Hokkaido, the north island of Japan. It is known that this sugar will keep your body warm. On the other hand, sugar canes are from Okinawa, the southern island of Japan - is known to cool your body.
