Since she posted photographs of her new teapot-shaped accessory on Twitter, with the simple message, “I made a travel bag,” Koyama’s images have been retweeted more than 14,000 times and picked up by a number of news outlets in Japan.

The teapot bag is both good-looking and functional, with a reinforced handle and a zippered “lid” to keep belongings safely inside. The well-made accessory is just the latest in a long line of innovative one-off designs by the talented artist, whose collection to date includes bags, clothing, scarves and zippered pouches.

Here, a traditional kimono becomes a frilly dress, complete with a colorful parrot plush toy that slots neatly into the obi sash around the waist.

This soft, squishy muscle vest adds a bit of humor to a hero’s outfit.

Her talent for fabric-based design is clearly evident in her bag range, which includes small grenade bags.
