Initially a simply-carved button fastener on the cords of an inrō box, netsuke later developed into ornately sculpted objects of craftsmanship.
These containers may have been pouches or small woven baskets, but the most popular were crafted boxes (inrō) held shut by ojime, sliding beads on cords.
Netsuke, like inrō and ojime, evolved over time from being strictly utilitarian into objects of great artistic merit and an expression of extraordinary craftsmanship.
This effect is particularly pronounced in netsuke, owing to long periods of isolation imposed both by geography and internal politics and limited avenues of self-expression for Japanese citizens due to custom and law.
[9][10][11] As a result, netsuke display every aspect of Japanese culture, including its rich folklore and religion, crafts, trades, and professions, all types of people and creatures, both real and imagined, and every kind of object.
As in other aspects of Japanese culture, the subjects portrayed by netsuke trend, over the long term, away from an initial emphasis on motifs of Chinese derivation toward a focus on objects of more strictly national interest.
[22][23] The Tokyo National Museum has a small exhibition room dedicated to displaying 50 of the 500 contemporary netsuke works collected by the Prince and Princess Takamado.
