i don't know if it's intended as a foreign aid program, but if it is, it's a foreign aid program whose budget amounts to a single google engineer's salary, so i'd think japan could do better

It's like U.S. doctors and contractors doing projects in Central America. Japan is very into building soft power in SEA through development assistance.
