China is said to be Japan's second-largest export destination. It has also been said that Chinese are 30% of what makes up the tourists in Japan. Cancellation of trips incoming and outgoing to China certainly affects its economy, that's why I am under the impression that Tokyo Stocks Exchange (Tosho) will drop even further. The 5-day index shows a 1.48% drop as we speak.

Having said that, we might expect them to look bullish on $BTC until they figure out where else to put the money withdrawn from Tosho. Therefore, I am not buying $BTC at the moment - instead would definitely wait for the dip. CAVEAT.
