The Robe of the Fire-Rat (火鼠の裘, ひねずみのかわごろも, "Hi nezumi no kawagoromo"), was a garment woven, as its name suggests, from the fur of the Fire-rat. It is an incredibly tough armor clothing and has regenerative properties. It once belonged to Tōga; however, he gave it to his human wife Izayoi after she gave birth to his half-demon son Inuyasha. It remained in Izayoi's possession until her death, when her son Inuyasha inherited it. Along with a container of rouge that his mother used, which was later shattered by Naraku, the robe was the only thing that he had left of his mother.
The robe is completely fireproof. The wearer is protected from both heat and flame. The robe is stronger than any human-made armor, allowing it to shatter un-empowered human weapons, deflect lesser yōkai swords, and absorb concussive pressure from high-powered explosives; the robes have allowed Kagome to survive being immersed in Naraku's highly-corrosive miasma without injury. However, as they are derived from a demon, the robe's powers can be nullified by purification barriers, such as the one that once surrounded Mount Hakurei. It becomes normal cloth and loses its defensive qualities when in such situations (although unlike a living yōkai it would not be destroyed). The robe is regenerative and mends itself. It has some connection with Lake Motosu that, with four other objects, unseals Kaguya's powers.
In The Castle Beyond the Looking Glass, when the robe was tore and stolen by Kagura, Kaguya cited the first part of the verse:
The white-hot flame of my love for you cannot burn this cloth of fur. My raiment, sleeves dried of tears, now on this day I don it.
Kagiri naki, omoi ni yakenu kawagoromo, tamoto kawakite kyō koso wa kime
When it was thrown into Lake Motosu, this second part was spoken:
Could you have but known that it would burn so swiftly, this raiment of fur, you would not then have sat with such little show of concern.
Nagori naku, moyu to shiri seba kawagoromo, omoi no hoka ni, okite mimashi o
- The Robe of the Fire-rat is based on the one in The Tale of the Bamboo Cutter (竹取物語, "Taketori Monogatari"), which is also fireproof.
- The Robe of the Fire-rat is a legendary clothing originated in Ancient China.
- Chinese legends of the fire rat are based on ancient Greek misconceptions of asbestos, a fireproof mineral with hairy fibers that can be spun into a cloth. Some ancient Greek writers believed the moist skin of the salamander, a type of amphibian, could douse flames. This concept was eventually confused with the aforementioned cloth derived from asbestos fibers to form stories of furry, fireproof creatures commonly described as rats.
