It's bull, Sega Japan has nothing to do with this and here's the plain and obvious reasons why.
1. The site is all in English ! (biggest and so obvious that you shouldn't need another reason).
2. Adds. Sega Japan NEVER use adds for anything apart from in house teams or Japanese affiliates. Never in their life would a big company like Sega want Play Asia or Google adds.
3. The mail addresses are very odd. Sega don't use these. I know because I7 get many official mails from Sega Japan.
4. Sega Direct links are pointless because it closes this month.
I think this is just a way to get peoples mail addressees for spam
