Thinking about what happened in Taken by Storm, I realized that Akio knows a lot more than I would have expected.
He knows that Dìqiú is connected with Zipang. That isn't exactly common knowledge, and he wouldn't have had any particular reason to investigate it before Corwin and Utena decided to honeymoon there. Either he found that while searching for something else, or he had somebody in Cephiro watching the wedding.
Akio also appears to know something that has him interested in artifacts that will offer him more power; Underground happens a day before Try, Try Again starts. No idea what - but it's clear that he's leaving a trail if somebody knows where to look, even if it isn't easily connected to him.
In comparison, knowing what would happen when he made his big push isn't that hard - get the White Lotus to provide a file on Korra, then get a map of Fort Tonraq, and he could probably work out where to go to grab his niece.
Still, he has a lot of cards in his hand. That is never a good thing.
Insert humorous comment here.
