A hot drink on a cold winter day warms the body and soul. In Japan, hot beverages like coffee and green tea are available in cans from the vending machines you can find on almost every street corner. Canned coffee and tea - available either hot or cold - are a Japanese invention. In recent years, many different kinds of canned coffees and teas have become available. And this Japanese invention has begun to spread to other countries. In the United States, for example, the global coffee-house chain Starbucks is selling canned coffee.
