If anyone is reading you can add Indonesia to Philippines , Vietnam , and parts of China as underdeveloped places with issues with pollution and sanitation. You gotta understand the condition of the ocean and how polluted the sea water is.

Be careful what u buy!

You probably won't hear about an authentic Japanese sushi bar giving you cheap stuff to eat IF the sushi master is born and trained in Japan 

If then NOT born and trained in Japan I would not go to that sushi bar

Thx for reading
