A tsunami rolls in and destroys all the construction that was being done on the inlet and the bay. Both the inlet and the bay were having a lot of construction done on them to repair the damage from the last tsunami, and then another tsunami rolled in and destroyed all that too. Bummer.
Imagine the Japanese people standing on the bay and the inlet as the tsunami approaches. “Eh (え)? What is that, Akiko?” “Eh? Where? Oh gawd, it’s a tsunami!!”
