In South Korea epidemic was started with one sick cult member spreading it to wast number of people. In Italy the person who started Lombardy cluster was first asymptomatic for weeks, was later misdiagnosed and spreading the disease in hospital. It seems that the epidemic is starting without similar super-spreaders in Japan.
Case fatality deaths to recovered rate in Japan is 18%. In South Korea it's 6.6%. This might indicate that Japan has 3X larger undocumented/documented rate.
This early in the exponential curve 2x difference is just 1-2 week delay.
