Yen weakness may be driving up the cost of food imported into Japan, but analysts say even pinched pocketbooks won't stop the country's consumers from getting 60 percent of their meals overseas.

"[Imports] probably will stay more or less stable in the long term unless Japanese agriculture can become more competitive," said Yasuhiro Enomoto, senior analyst at Marubeni Research Institute. In the short-term, however, he expects consumers will buy more domestic-produced food to protect their wallets.
