Japan has no sovereign wealth fund, but lawmakers led by Komeito have proposed a Japan Fund that would pool public financial assets, put by Nikkei Asia at about 500 trillion yen, under one agency. Returns would become a permanent revenue source. A private-member bill was filed in January 2026; it is not government policy and has not passed. S4 S1 S5
