Japanese League DVDs?

Yes, you can buy various season highlights etc., and some clubs do do DVD season summaries. However, you need an all zone DVD player to run them as U.S. and Japan are in different zones (1 and 2 respectively). A standard player will not show a DVD from another zone. You can often use your computer to run any zone DVDs as the players in computers are also all zone.

[Editor's note: While computer DVDs will often work as an any zone player, there are often BIOS (Basic Input/Output System) hooks that only allow the zone to be changed a limited number of times. You'll need to consult your computer's documentation to see what limitations are placed on you in the name of the MPAA.]

Yeah, you'd almost definitely need a Region 2 player.

I have to say, the Fighters 2006 "Big Dream!" 2-DVD set was fantastic. Not only did it have highlights of the entire post season, and information about the players and all, but it also had footage from the 1962 and 1981 Japan Series, and it had highlights of every Fighters game from the 2006 season. Not just the wins or the exciting ones, but even ones like "we came, we saw, we got our butts kicked."

Although it doesn't feature pro leagues, there's an excellent documentary called "Koko Yakyu" that was made about the Japanese high school baseball tournament at Koshien. It's a great insight into both Japanese baseball and culture in general. Just search "Koshien" under DVDs on Amazon and you can find it. It's sold in the U.S., so it will play on your U.S. DVD player. Highly recommended.

VLC Media Player is a free piece of software that also acts as a region free DVD player. If you have a wide screen LCD monitor, it'll also upscale video up to 16:10 ratio. I use it to watch my American DVDs.
