Osaka 1-day Unlimited Pass

Hi,
I'm wondering if this pass (2000Yen) can be purchased in Kyoto or Nara? The reason I ask is I'm coming from Kyoto or Nara by train to Osakako transferring at Bentencho where I will ride the Osaka subway straight away (ie before I have a chance to buy it in Osaka).

At subway station Bentencho you can buy the 1 day Osaka subway ticket at Yen 850 ( or Yen 600 on Fridays and the 20th of every month ).

You'd need to do an awful lot of subway travel in Osaka to make this worthwhile. I recommend the Surruto prepaid cards, which don't give a discount, but can be used on buses and subways in Kyoto, and the Keihan and hankyu electric railways, buses in Nara, as well as the subways in Osaka ie basically anything other than JR. We found it invaluable and easy as.

I plan to use the pass also for the Santa Maria cruise (which normally costs 1600Yen) and the Umeda Sky Buuilding (700Yen), so the pass already pays for itself not counting the subway travel. Here are the benefits: http://www.pia-kansai.ne.jp/osp/en/05a.php
