Yet we have an example from our lifetimes where an economic powerhouse, Japan, is still half of where it peaked 25 years ago.  

I don't want to be overly negative as Japan saw waves of deflation but RE price in good locations like Tokyo actually have risen the last 5 years.  

But if they go down into negative territory like they have in Japan and Europe, we could get a deflationary depression, which could be devastating to stocks and real estate alike over the long term.Why do I invest internationally even though it’s more complicated?

I primarily focus on properties in Japan where yield is high and properties are affordable between $25,000 and $55,000 on average with yield of 6% to 12% net pre tax.

And Japan has a nice tk rental play 

If it's a specific market in my region, like Australia, Singapore and hong-kong, I'll try to focus on the differences my particular niche (Japan) has compared to their own country.

I'm currently stationed overseas in Japan and enjoying the overseas life. 

In my escape, I have lived in the Philippines for a year and traversed Thailand, Japan and Singapore.

In Japan, the Nikkei 225 has dropped 50%.

Aeon mall from japan have build a mall there and planning on another one soon.
