That drop in exports was the first in ten months. You'll note in the linked post that exports fell to China, the EU and US. Weak demand for autos and the stronger JPY are cited as impacting.

- "It's possible that exports will continue to struggle in coming months in light of uncertainties particularly in the Chinese economy,"
- "The latest data serves as a reminder for the BOJ that a sharp rise in the yen can drag exports"
