Japan reports almost no street homelessness, 2,591 people in January 2025, down roughly 90% since 2003. But the count captures only people visible outdoors, missing net-cafe refugees, aging day laborers and couch-surfers kept from welfare by shame and bureaucratic rules. Japan exposes a universal measurement problem, including how the U.S. count misses families, youth and the doubled-up.
The 100,000 to 300,000 net-cafe estimates are extrapolations, not censuses, and the high end is disputed. How badly the U.S. count undercounts, and how much of Japan's drop is real versus hidden, are open, since countries define homelessness differently.
