Japan has a very high standard of living. It is considered as one of the most expensive countries in the world to live in due to the very competitive market and its position as an economic giant (even if now economy is not so good).
Japan widely exports food, drinks and agricultural products all over the world. Several Japanese staples like rice, noodles, seaweed, sake and soy sauce are sold in the millions. The country also imports a lot of food products from the United States and Europe like chocolates, snacks and prepacked hamburgers, meats and the like. The food in Japan can be expensive including raw materials like fruits, meat and vegetables.
Japan locally produces a lot of food as well. In comparing the price of locally made and imported products, there is not much difference since the Japanese heritage values its own products very much. One can find fair prices of noodles, bread, fruits and vegetables at markets and grocery stores. So long as people can keep within Japanese food staples such as seasonal vegetables, seafood, soya bean products and rice, they should be able to survive the high cost of living in Japan.
Usual fruits are orange, kiwi, Fuji apples and papaya. Meat products are also available but the more preferred fish and seafood array like tuna, salmon, squid, prawns tend to be quite expensive.
