About Mentougou
Mentougou is a strange beast: a district of 25 million people where you can rent a one-bedroom for $700/mo in the centre or $500/mo outside it, yet still breathe an air quality index of 85 and struggle with limited English. The expat community is very few, so if you need a built-in social scene, look elsewhere; if you want cheap rent and a temperate continental climate with 37°C summers and -7°C winters, it delivers. The 82/100 expat score and 84/100 FIRE score suggest it works best for budget-focused loners, not retirees or digital nomads chasing comfort.
About China
China works for remote workers and business expats fluent in navigating bureaucracy, not retirees seeking an easy landing. Rent outside the city center averages just $238.5/mo, backing the low COL index of 30.7. But with no retirement visa, no digital nomad visa, and an advisory level of 2, getting legal footing here is the real obstacle, not the budget.

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.
