Shiro Shirahata query

Shiro Shirahata (Japan) has published many books with superb photos of mountains. I own one -- on the Rocky (and Columbia) Mountains of Canada.

There are many great images, and I love the one on the cover of the version in the URL above. My question is: Is it possible to purchase a print? I have searched on the name but have found no leads. Maybe someone on here knows someone in Japan or has other ideas for this quest. One would think a famous photographer would want to sell prints.

The image in question is Lyell 5 (Christian) in perfect light.
