One rez cost to save two on a piece of ICE - that means it automatically is saving you a credit on the first piece of ICE he is used on. A three trash cost is a little difficult for the runner to trash, but if timed right it won't matter for the corp. If two or even three pieces of ICE are rezed in a single run with Akitaro in that server, he more than paid for himself and saved the corp a lot of money.
The major drawback is that he is limited to a single server. As Clot comes into its own and the meta shifts around it Akitaro could see a use. While he never really saw much play, bigger, more expensive ICE is becoming more popular, and although the economy can keep up, saving money would never hurt. The question becomes is he worth a deck slot over another upgrade, in the already tight corp decks?
