I am frequently asked how I watch Japanese baseball games here in the States. I used to use Justin.tv until Google shut it down a few years back. I then switched to win24tv.com, a Korean site, but I've never been very comfortable with it. I've always said that I would be willing to pay for something like MLB.TV for NPB but there isn't one. There is Pacific League TV but I was never sure about whether or not I could sign up for it without a Japanese address, bank account or credit card and whether or not I could view it from outside of Japan. And rather stupidly on my part, I never attempted to find out for myself.
It turns out that the answer to those questions is "yes, it is possible to sign up for PLTV from outside of Japan with a non-Japanese credit card" and "yes, it is possible to view the games on PLTV from outside of Japan". And it also turned out that it's ridiculously simple to sign up.
The easiest way to sign up is to use a browser that automatically translates Japanese to English (I use Chrome) and go to the PLTV website. There's a red button at the top of the page with text that says "利用登録" which translates to "On registration" (at least on Chrome anyway). NOTE - all the screen shots I'm going to show don't have the automatic translation - just to show how easy it is even without the translation.
Once you click on that, you'll be taken to a page that allows you to select what kind of membership you want. Your options are the "unlimited viewing package" (at either 950 or 1450 yen per month plus tax*), interleague only (flat rate of 1450 plus tax but it's only available from May 31 to June 19) or a single day's games (600 yen). I signed up for the "unlimited viewing package" and was taken to the registration page.
*You can get the 950 yen rate if you're a member of one of the Pacific League team's official fan clubs
I will point out that PLTV is currently doing a promotion where you can watch for free from now until the end of March so this page currently looks different than the screen shot I'm showing here.
Some of the elements on the registration page have English on them, even if you don't have them automatically translated. The page is long enough that I had to split it up into three screen shots. I'll go over each of them in order.
The red boxes labeled "必須" indicate required fields. The first two fields ("お名前" or "Your name") are your last and first names. The next two fields ("フリガナ" or "Yomi") (which are not required) are apparently used if the kanji version of your name has an alternate reading in hiragana. Since I suspect that most people reading this don't use kanji for their names, just leave these blank. The next field ("性別") is for your gender (obviously) and followed by your birthdate (生年月日) - the fields are for year, month and day. The next field ("お住まいの都道府県") is where you have to lie a little bit - it's for which Japanese prefecture you live in. I didn't see an "outside of Japan" option so I said "Tokyo". The next two fields ("メールアドレス" and "メールアドレス再入力") are for your email address - the second one is to confirm that you typed it into the first one correctly.
The next two fields ("パスワード" and "パスワード再入力") are for your password - again the second field is to confirm what you typed in the first one. The next field ("お好きな球団") asks for your favorite team - all 12 NPB teams are listed, not just the Pacific League ones. The next two fields (which are not required) are how you would specify if you belonged to PL team's fan club. The first field ("球団有料ファンクラブ") is where you select whether or not you're a member. If you select "Member", the second field ("対象球団/会員番号") will ask for which team and what your membership number is. The last field ("決済方法") is where you select your payment type - currently you can only pick credit card ("クレジットカード決済") but when I signed up a few weeks ago you could also pick some sort of e-payment plan offered by Yahoo! or Rakuten.
Once you're filled in all the required fields, click on the red button towards the bottom of the page labeled "利用規約に同意の上、ご入力情報の確認へ進む (Confirm)".
At this point, PLTV will send a confirmation email to the email address you entered above (assuming that they validated everything you entered in the form). That email will contain a link that you'll follow to confirm that you gave them a valid email. At this point you'll be asked to enter your credit card information.
The first field is for the number on your credit card. The next two fields are for the expiration date - month first, then year. The last field is a captcha code to confirm you aren't a robot. Once done, hit the big red button and PLTV will charge your credit card. With the 116 yen tax, the total was 1566 yen which worked out to around $14.
I hope this makes sense and is helpful. It was very simple to do and I'm regretting not having done it previously.
