South Korea vs Japan

In South Korea, the minimum wage is ₩10,320/hr ($6.62 USD). In Japan, it is ¥1,121/hr ($6.89 USD). Japan has the higher rate by 4% in USD terms. That nominal gap does not account for local prices; see the purchasing power comparison below for a cost-of-living-adjusted view. Workers in South Korea may retain a larger share of their earnings if prices there are lower.

The average gross salary in South Korea is ₩3,960,000/mo ($2,541.57 USD), compared to ¥398,333/mo ($2,448.12 USD) in Japan. In USD terms, workers in South Korea earn approximately 4% more. Average salaries reflect the full labor market, not just the minimum wage floor. The gap between South Korea and Japan is shaped by differences in industry composition, labor productivity, and the overall cost of living in each country. Workers in South Korea earn more in nominal terms, though how far that income stretches depends on local prices in Japan.

After adjusting for local prices using purchasing power parity (PPP), minimum wage workers in South Korea can afford more than those in Japan. The PPP-adjusted rate is $13 in South Korea and $12 in Japan. PPP converts wages into equivalent US dollar buying power, accounting for what a unit of currency actually buys locally. The 7% purchasing power gap means that even if the nominal wage in Japan appears competitive, minimum wage workers there face greater constraints on day-to-day spending.

Both South Korea and Japan mandate a similar standard work week of 40 hours. When work hours are equal, the country with the higher minimum wage delivers proportionally higher weekly earnings. Standard work week rules set the baseline; actual hours worked often differ based on industry norms and individual employment contracts.

While direct cost of living data varies by source, GDP per capita (PPP) gives a useful proxy for overall economic level. South Korea has the higher GDP per capita at $61,051, which is 1.2x that of Japan at $52,039. From South Korea's perspective, this means goods and services are priced at a higher economic level. A higher GDP per capita generally correlates with higher wages, higher consumer prices, and greater availability of goods and services. Workers moving between these two countries should expect significant differences in rent, food, and transportation costs.
