While this situation is largely due to the fact that the recent improvement in corporate profits has been supported by temporary factors, I believe that it also is attributable to firms' assessment that the domestic market has not yet improved sufficiently.
For example, while the recent improvement in current profits of large manufacturing firms has been brought about largely by factors that cannot necessarily be considered sustainable, such as the depreciation of the yen and low crude oil prices, the contribution of the increase in domestic sales volume to such profits is limited.
