Hengeyokai are a category of monster (or "yokai") within Japanese mythology. Technically a subcategory of obake (shapechanging monsters), although the terms are often used interchangeably, hengeyokai is a generic title used to cover an array of monsters based on the idea of magical animals who can transform into human form, and often times into other shapes as well. The term is actually pretty rare, and more usually these critters are identified as "bakemono" instead. The term is real, and would translate from Japanese as something like "changing phantom", it's just not commonly used - but then, Japanese mythology can be a right clusterfuck to try and unravel.
The list of hengeyokai is pretty damn long, and this is more a collection of the species most obviously connected to this term. It's muddled somewhat because many individual yokai of assorted species can learn to shapeshift, but these species are known to have it as inherent abilities.
Kitsune: Without a doubt the most iconic of all hengeyokai, the kitsune is a shapeshifting fox, often described as gaining multiple tails as its power increases. Cunning and seductive, but as likely to help humans as harm them, it has achieved a great deal of fame. A common myth-related saying suggests kitsunes tend to have seven different forms they can assume.
Tanuki: As popular as kitsunes in its home country, the tanuki myths have had a hard time getting abroad, mostly because of a certain bowdlerization issue. See, the jolly and happy-go-lucky tanuki are considered symbols of good luck, which is most prominently manifested in their enormous ball-sacks. Ironically, although typically depicted as more oafish and goofy than the sleek, elegant kitsunes, tanuki are even better shapeshifters, able to assume eight different forms - which may not be accounting for the stories of them turning their scrotums into things like the shop around them or a palanquin with servants to carry them about. Add in that the real animal, commonly known as the "raccoon dog", was only native to East Asian and that this sometimes lead to translators referring to them as "raccoons" or "badgers", and they've had a hard time getting known, although since the 2000s that factor has basically gone away.
Bakeneko: Shapeshifting cats are one of the most famous of the "lesser" hengeyokai. In fact, there are three different varieties of bakeneko at the least; the common bakeneko, who can be benevolent or malevolent as it sees fit; the two-tailed, almost always malevolent nekomata, who love to enslave, kill and eat people; and the kasha, particularly large and fiendish bakeneko who have a taste for corpse meat and are often servitors of hell. All varieties are known for having fire-creating and necromantic powers in addition to their shapeshifting.
Mujina: are shapeshifting badgers, very frequently confused with tanuki in the stories, to the point it's hard to really define them. Like tanuki, they are said to be capable of eight different transformations, and they're supposedly very shy and reclusive, which makes them much more careful about not giving themselves away when they do decide to walk amongst humans. Ironically, this means that Japan's badger-spirits have an attitude closer to the typical D&D elf, despite being more thematically associated with the dwarf.
Itachi: Without a doubt the most obscure of the "true" hengeyokai, itachi are shapeshifting weasels feared for their potent non-shapeshifting magic, which includes hypnotising people to become their slaves and gathering in groups to create huge firestorms. They are said to be the masters of shapeshifting, attributed with wielding nine different forms. Their cousins the Kamaitachi, a trio of super-fast weasels who run around knocking people over and cutting them with sickles, are much more famous.
Kawauso: A more obscure hengeyokai, the kawauso are jovial and friendly shapeshifting otters, who mostly take on human form to play tricks and buy booze.
Sazae-oni: These aquatic hengeyokai are based are turban snails - a sort of spiky sea snail native to Japan - that learn to take on the form of beautiful women in order to lure victims to their doom.
Jorogumo: These are the closest thing in Japanese mythology to a succubus; female spiders who assume the form of beautiful maidens in order to seduce and usually devour men. Their name literally means "whore spider" in its original format, although politeness means the modern version of their name is written with characters that translate as "entangling bride".
Tsuchigumo: Like the jorogumo, these are shapeshifting spiders, but tsuchigumo are more powerful, ambitious and politically minded. The other big difference is in the species; jorogumo are based on golden orb-weavers, whilst tsuchigumo are based on purseweb spiders.
Unagi-hime: Among the more obscure hengeyokai, these are female eels who assume human form in order to interact with humans, often to beg for their assistance in battling other yokai who want to claim their homes.
Beyond being natural monsters to try and include in games with more of an oriental theme, hengeyokai have appeared in two different roleplaying games.
First introduced in the very first edition of Dungeons & Dragons via the "Oriental Adventures" splatbook, the D&D hengeyokai is treated as a singular race divided into sub-races based on which animal forms it can take. This is perhaps the laziest way to handle it, because hengeyokai actually covers a wide variety of different animals who just happen to have "assume human form" as a common trait, but it seems fairly cemented in tradition: D&D has had the hengeyokai appear according to this formula in every edition from 1st to 4th, and they're absent only in 5th edition so far.
Precisely what animal forms of hengeyokai have been availible have varied depending on the edition:
- In 1st edition, appearing in the 1e Oriental Adventures, the hengeyokai species available were Carp, Cat, Crab, Crane, Dog, Drake, Fox, Hare, Monkey, Raccoon Dog, Rat and Sparrow.
- In 2nd edition, the hengeyokai received an informal update in the Kara-tur Monstrous Compendium, which updated all of the 1e subraces. Their ranks were then bolstered by Dragon Magazine #266, which added more races to the lineup: Badger, Dolphin, Falcon, Frog, Lizard, Lynx, Octopus, Owl, Panda, Turtle and Weasel.
- In 3rd edition, under the 3e Oriental Adventures, a new lineup appeared that blended elements of both of the previous lists: Badger, Carp, Cat, Crab, Crane, Dog, Fox, Hare, Monkey, Raccoon Dog, Rat, Sparrow and Weasel.
- In 4th edition, hengeyokai were again relegated to Dragon Magazine, with the lineup of volume #404 starring the Badger, Carp, Cat, Crab, Crane, Dog, Fox, Hare, Monkey, Raccoon Dog, Rat and Sparrow.
AD&D 1e PC Stats
- Ability Score Minimum/Maximum: Strength 12/18, Dexterity 9/18, Constitution 12/18, Intelligence 12/18, Wisdom 12/18, Charisma 12/17
- Class & Level Limits: Shukenja 8, Kensai 6, Bushi Unlimited, Wu jen 9
- Movement Value: 12'
- Shapeshifting: A hengeyokai can change form once per day per level; once it has exhausted this ability, it must remain in its current form until the next day. Changing form takes a full round to complete, and all armor & equipment is left behind when it transforms. Spells that reveal illusions do not affect a hengeyokai in its animal or human forms.
- Animal Form: A hengeyokai in animal form can only speak the hengeyokai and animal languages in this form. It cannot use weapons, armor or equipmient, nor can it cast spells. In animal form, its maximum hitpoint value is halved (round up); damage from one form carries over and it cannot assume animal form if this would leave it with 0 or less hit points. If reduced to 0 HP in animal form, the hengeyokai is slain outright. It gains certain other traits in animal form dependent on its subrace. All hengeyokai have infravision 120 feet in animal form.
- Bipedal Form: Now appearing as a humanoid animal, the hengeyokai retains the ability to speak to animals and its infravision, but has access to all of its normal abilities. However, it loses any special movement rates, such as fly, swim, or increased/decreased land speed, cannot use any natural attacks, and does not benefit from an altered base Armor Class.
- Human Form: In human form, a hengeyokai loses its animal-speech, infravision, natural attacks, base armor class and special movement traits, but retains all of its class abilities.

The Old World of Darkness attempted to broaden its appeal by doing "Oriental Flavors" for several of its gamelines. Out of the original Changing Breeds sourcebook, came the Oriental Therianthropes of the World of Darkness, in the form of the Hengeyokai: Hakken (werewolves), Khans (weretigers), Kitsunes (werefoxes), Kumo (werespiders), Nagahs (wereserpents), Nezumi (wererats), Same-Bito (weresharks - one of which you fought in the Vampire the Masquerade Bloodlines vidya game), Tengu (wereravens) and Zhong Lung (weredragons).
It goes without saying that hengeyokai are actually pretty classic monstergirls, with many real-world myths revolving around them assuming the form of sexy human women for a night of fun or even to score themselves a cute human husband. Of course, some of those stories also depict them as seductive predators who eat their would-be lovers, either before or after the sex, but that is why they call them monstergirls.
Precise behavior will depend a lot on which type of hengeyokai you're actually dealing with, and even then, there's often a certain amount of fluidness - kitsune, for example, can be anything from free-wheeling hedonistic party-girls to enigmatic seductresses to playful pranksters. The most common trait is that the hengeyokai will usually be desperate to hide what she is at first, often because she's scared that the guy will freak when he learns she's really a cat or a weasel or whatever.
Appearance, likewise, is heavily fluid; a hengeyokai can appear as anything from a human with some "symbolic" traits of their animal form to the classic "girl with animal ears and an animal's tail" to a full-on beastfolk. Add in their shapeshifting abilities, and things get more complicated. There is a slight tendency to give them three forms; human girl with animal symbolism, girl with beast ears & tail (which the Japanese call "kemonomimi") and either female animal or female beastfolk. Four-fold or five-fold shifters are very uncommon.
