Having said that, I do not believe that recent exchange rate  7  movements indicate a situation of "unhealthy" yen depreciation that could lead to stagflation.
In fact, I see the yen's recent depreciation as having some positive aspects for Japan; it is supporting business fixed investment by contributing to the increase in profits of Japanese firms' overseas subsidiaries and to Japanese exporters' bottom lines. It is also encouraging overseas firms to consider establishing a corporate presence in Japan, such as by building manufacturing facilities.
