A set of six Kan’ei Tsuho, copper coins that were once used for currency, are also included in the set. The six coins make up the symbol of the Sanada clan.

A skilled calligrapher lends his hand to the project.

Limited to 666 items, the covers are available in these gorgeous four-piece packs for ¥27,000 each (about US$227).

Deluxe editions featuring a lacquered box, serial number, and calligraphy are available for ¥60,000 (about US$505).

The rokumonsen (six coin) motif is beautifully embossed on the red suede smartphone covers. This is the emblem of the Sanada Clan, as seen on Yukimura’s distinctive helmet.

All purchases come with a free entry ticket to the Kudoyama Sanada Museum, which is due to open on March 13, and will feature exhibits related to Yukimura and the taiga drama (year-long historical fiction television series) in which he stars.

To see the attention to detail and the amount of work that goes into making each of the beautiful smartphone sheaths, take a look at the video above. Watching traditional craftspeople at work is always a wonderfully relaxing experience!
