More than two months have passed since the devastating earthquake and tsunami hit the northeast coast of Japan. Among many aftereffects, shifts in the global supply chain have impacted businesses and people worldwide. The damage to Japanese ports, vessels, and factories has been grave. As expected, U.S. imports from Japan took a dive from March to April, decreasing 13.22%. Below is a graph of U.S. imports from Japan for the past 2 years.

A breakdown of Japanese ports illustrates that while many ports posted a decrease in exports to the U.S., others have actually increased exports since March. The Port of Sendai, in particular, is the port that was closest to the disaster area and worst hit; reports indicate that it will likely take many months for the port to resume activity. The ports of Kobe and Osaka, conversely, managed to increase TEUs exported to the U.S. by 10.52% and 11.02% respectively from March to April. Below is a chart showing the top 10 Japanese ports.
