Diners Club Club Rewards - Diners Premium card citibank in Japan

Hello.
I have had the Diners Premium citibank card in Japan for 6 months now but I have yet to find the "real" benefits for Platinum card members in Japan or using it around the world.
What am I missing?
Thank you!http://www.diners.co.jp/premium/index.html

hi, bibu.

you must login from here
https://dinersclub.diners.co.jp/JPDIC/JPS/portal/LocaleSwitch.do?locale=en_JP&N0=0&N1=0
and click onto 'CUSTOMER SERVICE' -> 'Menu for Diners Premium Member only' then you may see all benefits.

That maybe a big differnce from US/EU/ other Asian programs is the bonus.
100 bonus points for every JPY1M purchases in a membership year (1,000pts. max.). This means double points.

You can convert points into AA/KE/NW/UA/AZ/TG/NH miles. (10pts. = 1,000miles) for free I think that as you know it. (NH: 400pts. max. per year)
