What are its characteristics? What does it look like?
Raccoons have gray-brown fur and black markings from around the eyes to the cheeks. They are often mistaken for raccoon dogs, but they are a different species. The difference between raccoons and raccoons is that raccoons have black horizontal stripes. The underside is gray or light brown, the area around the eyes and mouth is black, and the nose and chin are white. They live in forests and grasslands. They can be found in wetlands and coastal areas, as well as farmland, suburban areas, and urban areas.

Flexibly changes diet depending on the season and environment
- Behavioral Characteristics
Nocturnal
Good at climbing trees and swimming
Quickly flees when threatened
Curious and often exploratory

What is their personality like?
Raccoons often live in rock cavities and are somewhat timid. They have poor eyesight and the antennae on their palms are very well developed, so despite their cute appearance, they have very aggressive personalities. They may bite or scratch you. They often forage near water in the evening and are very good swimmers.
- Basic Personality
Very curious
Easily interested in new objects, sounds, and smells
Highly intelligent and cunning
Good at trial and error
Repeating successful methods
Highly cautious
Quickly flees when threatened
Can become aggressive when cornered
- Aggression
Usually avoids people
However, they are dangerous in the following cases:
No escape route
Rearing their young
Food is being stolen
Sharp teeth and claws, with powerful bites and scratches
- Sociality
Primarily solitary
Does not form groups except during breeding season
Mother-child bonds are strong but temporary
- Personality as seen in relationships with humans
Perceives humans as both a threat and a food source
High learning ability:
Learns when to take out the trash
Adapts to human lifestyles
Even when accustomed to humans, they are not necessarily tame animals
What is their ecology?
Raccoons are omnivorous, eating amphibians and fish as well as fruits, nuts, insects, small animals, and bird eggs. Their breeding season is from February to June and they are polygamous, with a gestation period of about two months. They can give birth to 1-7 pups at a time. The newborn pups open their eyes around three weeks after birth and have a nursing period of 70 days. They are said to live for about 10-20 years.
- Life Rhythm
Nocturnal
Active in the evening and at night, resting during the day
Range of Activity
Depending on the environment, it can be as large as several square kilometers
Range of activity is relatively small in urban areas
Resting Places
Tree holes, rock shade, underbrush
In urban areas, they also use attics, warehouses, and sewers
- Diet (Very Flexible)
Omnivorous
Fruits, nuts, grains
Insects, crustaceans, frogs, fish
Bird eggs, small mammals
Human food scraps and pet food
Feeding near water
Searches for food using its front paws
“Washing” behavior is confirmed by touch
- Breeding and Rearing
Breeding Season: Mainly Winter to Spring
Gestation Period: Approximately 63 days
Labour: 2-5 pups (average 3-4)
Rearing
Only the mother is responsible
Nursing Period: Approximately 2-3 months
Pups stay with their mother until autumn
- Social Structure
Generally solitary
Males’ territories may overlap, but they do not cooperate.
Females have limited territories during the rearing period.
They do not live in groups, but they do gather temporarily at feeding areas.
- Motor Ability and Adaptability
Excellent at climbing trees.
Excellent swimmers.
High intelligence allows them to quickly adapt to new environments.
Ability to overcome man-made obstacles (garbage cans, traps).
They do not hibernate in cold regions, but their activity is reduced.
Do they have any natural enemies?
Raccoons have no natural enemies, are omnivorous, and have a strong reproductive ability, so their very fast reproduction is a concern. Damage to ecosystems and living environments often spreads rapidly, and farmers are also suffering a lot of damage. They can also climb trees, so measures are needed.

Are raccoons an endangered species?
Raccoons are invasive species, but according to the Ministry of the Environment, they are not endangered. In recent years, raccoons that have become wild and are invasive species have caused many damage to crops, as well as problems such as living in attics and destroying houses. Some municipalities have caused serious damage to urban development, and there are instructions for extermination, so check the site map on the official website for procedures. They invade houses for disaster prevention, so measures such as capture are necessary.
Raccoon Conservation Status
IUCN Red List Classification:
LC (Least Concern)
👉 Classified as a species with little risk of extinction.
Why not endangered?
① Extremely large population
Estimated to number in the tens of millions, mainly in North America
Wide range, with stable or increasing population
② Exceptionally high environmental adaptability
Adaptable to forests, wetlands, farmland, and urban areas
Able to utilize artificial environments (garbage, buildings)
Omnivorous, so food is readily available
③ High reproductive capacity
Gives birth to 2-5 litters per year
Relatively high survival rate of young
Can raccoons be kept as pets?
Raccoons are designated as specified invasive species, and the purpose of keeping them is limited to academic research, exhibitions, education, etc. Therefore, ordinary people cannot keep them as pets. There is a high possibility of spotting them in various places, and if you see one nearby, it is dangerous to leave it alone. Depending on the location of birds and animals, safety measures are necessary.
① Legal Status (Japan)
❌ Keeping Raccoons as Pets Is Illegal
Raccoons are designated as “Specified Alien Species.”
As a result, the following are all prohibited:
Keeping
Purchasing/Selling
Transferring
Transporting
Release
📌 Keeping pets in private homes is strictly prohibited.
Violations are subject to fines and imprisonment.
② Why can’t they be kept as pets?
- Serious Ecosystem Impact
Predates on Native Species (Frogs, Birds, Insects, etc.)
Destroys Ecosystems
Serious Crop Damage
- Highly Dangerous
Becomes More Aggressive as It Grows
Bites and Scratches are Extremely Dangerous
Strong and Difficult to Control
- Diseases and Infectious Diseases
Rabies (Overseas)
Raccoon Roundworm (Serious Human Health Risk)
May Carry Bacteria and Parasites
③ Regarding the “Old-Times” Myth
1970s-1980s
There was a time when they were imported and kept as pets
After they grew older:
Became uncontrollable and were abandoned
Became Feral → Spread Nationwide
👉 This is the cause of the current invasive species problem.
④ Can They Be Kept Overseas?
In some countries and states, it is legal under certain conditions.
However:
Prohibited or severely restricted in many countries and regions
Requires specialized facilities and licenses
👉 There are almost no countries where it is “easy to keep them.”
