Thanks all for the comments to my part 1. 

 As I wrote in part 1 there have been some TV interviews in Japan this off-season. Part of it is the interview of NHK which has been reported by Brad Lefton
Doctor: "Ichiro has a very fine prefrontal cortex"

For 70 days over three different spans of last season, a four-person, one-camera crew (of which this writer was a member) followed Ichiro's every move, trying to discern his professional methodology.

Here some pictures from the TV (Sorry for bad quality because I made camera shots of TV). First picture is Ichiro commuting in his car (Ichiro likes super sports cars and has some of them).

Next picture is Ichiro eating home made curry.

The camera discovers that Ichiro has eaten the same lunch before home games all seven years he has been in Seattle — homemade Japanese curry from his wife Yumiko. Not variations of her recipe, but the exact same kind every single day. And on the road, he almost always opts for a cheese pizza, easy on the sauce and fluffy around the edges, if you must know.

Now other pics which have not been mentioned in the Seattle Times article:

 

Ikkyuu hi-five with Yumiko-san. When Yumiko-san watch Ichiro's game at TV and he gets a hit Ikkyuu hi-five with her.

Now back more to  baseball related interviews. In all the interviews Ichiro was very confident.
He was confident because he found out the ultimate swing in 2007.

Why?

He found his perfect swing! Or the beginning of his perfect swing.

What is it? Go to MLB.com and watch the video of his swing.
