So, living in Germany, first it is not easy to get them... but one can do it...
1. Step Register a new account
a)
You need a http://www.amazon.co.jp/ account ... it is easy.
Here is a link to a Japanese kindle Go book:
http://www.amazon.co.jp/gp/product/B00E ... d_i=489986
Right below the "shopping cart sign" are some japanese letters, they are saying:
"Would you like to see this page in English? Click here." If you not find it, use a translator like the one embeded in Chrome browser.
b) register a new account with a new (not your amazon.com email, that avoids confusion) Email adress.
2. Payment method: (The tricky part)
you have to have a Japanese Credit Card!
Or some folks on the internet were saying that you just need a normal Mastercard or any other normal credit card like that, and can give a "random/fake" adress (because they just check the number of the credit card and the exp. date) .... I was of course not doing that, i used a Credit card of a Japanese friend of mine...
3. Register your Kindle or Kindle App
in my case it did not work with my App on the MAC OS ... i think it just cheks Amazon.com and Amazon Europe accounts... but on the i pad i could put in my new email adress which i was using for the Japanese Amazon account... and it worked... the Kindle showed up in the Japanese Amazon "manage your device" section.
4. One final thing: you have to activate the payment option for the Kindle seperatley again in the Amazon.Jp account ... it is not enough to just register a new payment method in general, there is a special menue point just for "Kindle payment"
5. Finally: I paid 8 Euros for all 3 (!!) Go Seigen tsuemgo collection books!!!!!!

So maybe that will inspire you to go shopping ...
6. I recomend using Chrome browser with translation function embeded, so you can browse all thoose Go books and can get easyli a glimpse what they are about...
