About Koga
Koga is a small, affordable Japanese city where a single adult can live comfortably on $1,350/mo, with one-bedroom rents of $550/mo in the center and $420/mo outside it. The tradeoff is real: English proficiency is limited, the nearest airport is 18 km away, and the retiree and digital nomad scores of 67 and 66 lag well behind the overall expat score of 80. If you want cheap rent, low crime, and good healthcare without big-city noise, Koga delivers, but the Japan Digital Nomad Visa's $6,667/mo income floor makes it a poor fit for most remote workers. Come for the budget and safety, not for the nightlife or the networking.
About Japan
Safe, efficient, and financially punishing for anyone chasing early retirement. A 1BR in central Tokyo runs $531.81/mo, cheap by American standards, but progressive income tax up to ~55% (incl. local) erases most remote-work savings. No retirement visa exists, and the digital nomad route requires $6,667/mo income with zero path to permanent residency or citizenship without a long, difficult grind.

About Tokyo
Tokyo is the rare megacity where a $1,280/mo one-bedroom downtown still feels like a bargain against a 51/100 cost of living index and a $2,956/mo average net salary. The tradeoff is space: you are paying for efficiency, safety, and a 90/100 safety index, not square footage. English proficiency is common in tourist areas, so daily life works, but the large and active expat community in Minato, Shibuya, Setagaya, and Ebisu is where you will actually settle in. If you can stomach the language barrier and the crowds, Tokyo rewards you with excellent healthcare, 200 Mbps internet, and a digital nomad score of 88/100.
