Ai is a plant that gives us this natural blue color.

Ai-zome leather (Dyed with rare natural dye)
Ai-zome leather is produced by immersing natural leather into the ai dyeing liquid many times with natural-plant-indigo-dye technique, and hand-dyeing one by one carefully. The depth of color, variances, and clear color are expressed in the leather as features of Ai-zome, which is “JAPAN BLUE LEATHER.”
