For example, Japan's low labor productivity is well known as being lower than that of other  9  advanced economies. If we take a look at this situation from another perspective, it can be said that there is ample room for Japan to expand its economy's supply capacity as the effects of hysteresis dissipate.
Indeed, Japan's labor productivity recently has been improving at a relatively fast pace to catch up with other economies. The expansion of the economy's supply capacity, in the short term, has been working in the direction of easing the upward pressure on wages and prices associated with an increase in demand. However, there is no need to be unduly pessimistic about the current situation.
