Yup, those are identical to the temple stock.

Mind you, Japanese temples have a tradition for selling bulk tourist stuff (referencing here Nakamisedoori leading to Sensoji in Asakusa and other roads leading to Minobu, Ooyama and thousands other temples). For the really expensive stuff, I'd suggest the small serious shops around Asakusa, the ones that sell the real tomb stones and lackquered oak home altars. Via net, I have no idea, sorry.
