Rikuro Cake from Osaka

As per Rikuro website, it's only carried in Osaka. Does anyone know whether this is the case or not. Can I find this cake in Tokyo? Also, if it's not available in Tokyo, as per their website, it can be ordered. Since I can't speak Japanese, do you think the hotel will be able to order it for me?

Is there any other channels that I can buy this cake? It's very tasty.

They seem to have several shops in Osaka and Kobe, that's it. They do take phone orders for some of their products:

This page has the phone number and shipping information. They deliver for "cash on delivery."

If you are staying in Tokyo for several days, I suppose you can ask the hotel to call them up and order on your behalf. They to not seem to ship on the weekends, and also they have only so many cakes they can ship per day, so you need to (get someone to) call and ask about availability as well.
