Japan is not just home to giant crabs, but they are also known for getting some pretty bad tsunamis too. Of course, many Asian territories such as the Philipines also deal with their fair share of them too. Tsunamis are unique events, and would likely make anyone anxious. Thus, you do not need thalassophobia to be afraid of them. This particular image shows giant waves destroying an area in Natori, Japan in 2011. Luckily, most of the area has recovered since this event.
