I'd love to know if it's possible to find these in Europe. I looked around some more and less popular outlets, but not much from Segoe is available.
I think it's easiest to order from amazon.co.jp, but as far as I know, they don't ship books from third-party sellers outside Japan. I've ordered my set of the 囲碁の力を強くする本 books while in Tokyo in 2013; they were delivered to the hotel without problems.
So if you go to Japan or know someone who will bring the books for you, that's an option.
As far as I can tell you only need a Japanese address and they will ship to you anywhere in the world after that. I ordered items from amazon.co.jp while I was living in Tsukuba for a research visit, and have since had no problems having books shipped to Canada.
