GDP per capita is but an estimation, but the larger picture is gdp growth rate (nominal terms) , number of foreign direct investments, job creation per annum, and the demographics of jobs created by industry. There's no way Japan is 'responsible' for the Philippine economy, but i will say that Japan is an active partner , active investor (actually the largest FDI in the Philippines, as well as the largest trading partner of the Philippines). So we can say that Japan 'contributes' to the growth of the Philippine economy, but not responsible for the Philippines' success. The ones responsible for said success are the Filipino people, Filipino businessmen, and the leadership in Malacanang.
What matters is how well the people life. Phil has one of the worst life expectencies in ASEAN. It has lower income than Nigeria. It has among the highest crime rates in all of Asia except for those torn by civil war.
In that case which country isn't a "success" aside from North Korea, Syria and Zimbabwe?
