My solution be for let's say Japan would be to peg everything from wages to mortgages to the US dollar. Now with deflation you will be making losses in yen as the value of yen to the $ will keep increasing but in dollar terms and in actual buying strength you will still be improving. Though this will be something very hard to do and everyone would want to keep the yen instead of holding any asset.
