From the JP wikipedia: 徳島藩主の蜂須賀家に伝来. 個人蔵.

Rough translation: It has been handed down over generations by the Hachisuka family from the Tokushima Daimyo/Lord. Is currently in a private collection.

The private collection part would probably explain why it's hardly seen, since a lot of the other swords are held by museums, hence the easy availability of photos.
