Googlefish translated link to Eagles’ press video page at niconico.jp.
Aggravtingly, the Yahoo.jp NPB news page and the corresponding Eagles schedule resist the Googlefish.
There does not appear to be an iPad video player app for niconico.jp available in the App store, and attempting to play the videos once registered presents what appears to be a technical compatibility note that mentions OS X, IE, Windows, and Flash, but not iOS.
Additionally, I was able to register at both the English-language niconico.com and the Japanese-language niconico.jp with the same username but different associated emails. I suspect that this indicates a fully-segregated user-management and content system. Backing up that speculation is the fact that the active English-language userid was not accepted as a login from the Bionic Eagles page.
In the past, it seems that the Yahoo NPB Pacific League portal was one of the ways to view the games. The playback was geo-restricted in some way, however.
I have yet to try the niconico.jp playback of the last-season videos on a desktop operating system.

UPDATE: if I am logged in at niconico, the page won’t render in translation. Proceeding untranslated, each individual video will not play despite my being logged in, something I assume which represents geo-blocking.

Therefore, my next steps are to work through the use of proxy servers to provide in-Japan IP spoofing.

As I have been hacking away at this, I am put in mind of my fascination with manual tuning of scrambled pay-cable channels as a kid. My parents wouldn’t pay for HBO as a part of their cable package, and the methodology used to keep premium channels out of view was an analog variable transmission scrambler, or something. The end result was if you manually wiggled the fine tune knobs on the TV and the cable box at the same time, you could occasionally get glimpses of partially unscrambled content.

I would do this for hours, not because of the content, but because I couldn’t get to the content. It seems clear to me that I am in the same sort of dynamic here.

So, last year I forked over for MLB.tv without understanding the minutiae of local area blackouts and the like. I was pissed, and of course the blackouts did not really matter, as I just went ahead and watched the firmly, absurdly illegal video feeds I had started watching the season on. In essence, it was a classic case of a missed sales opportunity – the shitty free product made me want the nice, cushy product.

Well, maybe not a missed sales opportunity.

At any rate, I had the presence of mind to look at my MLB.tv account on January 31, and learned that was in fact the actual day it it was set to auto renew. Naturally, I cancelled.

Out of curiosity, I then went back to each of the devices I had associated with the account last year and to my astonishment I retain access to the 2011 season.

In October of last year, I attended a show by Chicago band Shellac at the Vera Project and during the show, people began sending me texts that maybe I should be watching game six of the Rangers-Cardinals World Series.

All told, this means I can catch that game now.

I have been scrubbing the inarwebs for the equivalent of MLB.tv for Japanese pro ball, and have yet to come up with the solution. Apparently the media provisioning is very robust in Japan, but only for Japanese-located consumers. This means that English language discussion of the material is pretty limited. Additionally, online streaming access appears to be contracted at a team level in the older, more popular Central League and to be centrally administered for the Pacific League (home of the Eagles, the team I follow).

Surprisingly, to me, there does not appear to be the equivalent to the Dubliner or the George and Dragon in Fremont and Ballard, respectively, bars that feature in-house broadcasts of European sporting events, catering to expats. Honestly, you would think at least ONE bar in Seattle, of all places, would offer live or time shifted Japanese pro ball. I suppose there is some sort of marketing opportunity here.
