China's Economic Woes Echo Japan's 'Lost Decades,' Threatening Japanese Economy Again

China's economic troubles like stagnant growth and property sector woes echo Japan's lost decades and could hurt Japan's economy.

Every 10% drop in Japan's exports to China reduces Japan's GDP by 0.4%, so slowing Chinese growth badly hits Japan.

Weak Chinese demand has made the Bank of Japan wary of exiting its ultra-easy monetary policy despite high inflation.

The yen's sharp drop this year worsens imported inflation, suppressing wages and consumer demand in Japan.

Japan failed to reform much except corporate governance, leaving it vulnerable as China slows.
