No it isn't. In purchasing power terms Japan has been, or is about to be overtaken by Poland and Slovakia [1]. This is largely due to demographics and the declining share of the working age population. There is nothing that impoverishes countries more. Gradual decline feels fine for a while, until it doesn't when the bulk of the workforce ages out.

Japan demographic crisis is due to a mismanaged economy where many Japanese leave the country to find work. They are also not interested in mass immigration.

Does this not speaks to the rapid growth of Central Europe economies rather than a decline of Japan? I have read similar comparisons for both the U.K. and Germany vs Poland.

Also, a quick googling suggests both Poland and Japan both have fertility rates around 1.2. Working age of Poland is 65% of the population vs 60% for Japan. So a bit worse.
