Ginger seems to be a boom in Japan since it is effective of warming the body and improves our metabolism. It maybe common in Sri Lanka but nowadays ginger tea became very popular and sells well in Japan. Other products made from ginger seem to be sell well, too. Recently I am also trying to have ginger whenever I drink Sri Lankan tea. I think I could have a good sleep after that. I would like to keep trying to have ginger. By the way, our ginger which attached with sushi is made at Cafe Japan. Hope you enjoy it.
