Tamagotchi: The Digital Pet From Japan

How a tiny egg-shaped keychain from Bandai turned pet care into a worldwide craze, and why it keeps hatching new fans.

Quick answer: Tamagotchi is a handheld digital pet made by Bandai that went on sale in Japan on November 23, 1996. Owners raise a tiny creature on an egg-shaped device with three buttons, feeding it, cleaning up after it and playing with it as it grows. Bandai Namco reports sales approaching 100 million units worldwide.

Tamagotchi is one of the great success stories of Japanese toy design, and people still ask where it came from, how it works and whether the modern versions are worth buying. The idea was simple: a pet small enough to clip to a bag, with no fur, no noise and no walks. That simple idea spread across the world within a year and has never really left. This guide explains the origin of the name, how the original toy worked, how the line has changed over the decades and how first-time owners can enjoy one today.

What a Tamagotchi actually is

A Tamagotchi is a small plastic device with a screen, a few buttons and a loop for a keychain, and it holds a virtual creature that needs regular care. The shell is shaped like an egg, which is where the name comes from: tamago is the Japanese word for egg. The design was first conceived as something that could be worn like a wristwatch, and the fun comes from checking on the pet throughout the day.

The creature on the screen has needs that rise and fall over time. Early models tracked hunger, happiness and training, and the pet would call for attention with a beep when a meter dropped. Owners respond with a few button presses to feed a meal or snack, play a simple game, switch off the light or clean up droppings. If the pet is neglected it can become sick, and with poor care it may die, after which the owner can restart with a fresh egg.

This gentle rhythm of small, frequent check-ins is what made the toy different from a video game. There is no score to beat and no level to clear. The reward is watching the character grow through different life stages, with the final form depending partly on how well it was looked after.

How the toy was born in 1996

The Tamagotchi was created by Aki Maita of Bandai and Akihiro Yokoi of the toy company WiZ, and the two later became known as its mother and father. Maita is widely credited with the starting idea of a pet for children that would not bark, shed or need a vet. Yokoi helped shape the concept into a working toy with its own character and story.

The first Tamagotchi went on sale in Japan on November 23, 1996. Bandai sold roughly 400,000 units that first season, according to figures summarized on Wikipedia, which was a strong debut but only the start. International release followed in 1997, with the United States launch on May 1 of that year.

In 1997 Maita and Yokoi shared an Ig Nobel Prize in economics, a lighthearted award given for achievements that make people laugh and then think. The prize recognized how many working hours people spent feeding their virtual pets, a playful nod to the scale of the phenomenon. It remains a fun piece of trivia that shows how far the toy reached beyond the toy aisle.

The craze that followed

Sales climbed quickly after the first holiday season, and reported figures show about 10 million units sold by July 1997 and about 13 million by October of that year. By the spring of 1998 the total was reported at close to 40 million worldwide, including roughly 12 million in the United States and Canada. These numbers come from sales summaries compiled on Wikipedia, and they place the toy among the biggest hits in toy history.

The toy also helped define a style of play built around short, frequent check-ins. It fit in a pocket, clipped onto a bag or keychain, and was easy to show to friends, which suited the way many people move through a busy day. Its popularity also inspired other makers to release their own virtual pets.

Bandai Namco has continued to publish lifetime sales totals in its annual fact book. As of 2025 the total was reported at about 98 million units, so the toy has nearly reached the 100 million mark across nearly three decades.

Growing up: the life stages

Most Tamagotchi models follow a familiar path from egg to adult. The egg hatches within minutes after the clock is set, producing a baby that needs frequent attention. It then grows into a child, a teenager and an adult, and some models add a special form or a senior stage.

The character you end up with depends on care choices. Different versions use different rules, but in general a pet that is fed on time, kept happy and cleaned up after will grow into a healthier or more popular adult form. Models with several possible adult characters encourage owners to try again and see which form they can unlock.

The best-known character is Mametchi, a mascot who has appeared since the original release and later starred in the 2007 film Tamagotchi: The Movie. Other characters have been added over the years, and each generation of toys brings its own cast and its own small surprises. Because every version has slightly different rules, the instruction booklet is worth reading before you start.

Modern versions and special editions

Bandai has kept the line alive by adding new technology while keeping the egg shape. Tamagotchi Connection, released in Japan in March 2004, let pets visit one another through infrared, so owners could trade gifts and play together without cables. This was an early example of the social play that fans enjoy at meetups and conventions.

Tamagotchi Uni, released internationally in July 2023, was the first model with Wi-Fi and a smartwatch style band, and it connects to an online space called Tamaverse. Updates have added downloadable content over time. Tamagotchi Paradise arrived internationally in July 2025 and returned to the idea of a small pet, with a zoom dial for closer views.

Collectors also look for special editions of the smaller Tamagotchi Nano. Bandai has released licensed versions based on well-known characters such as Gudetama, Hello Kitty, Neon Genesis Evangelion and Pac-Man, with many appearing first in Japan. Availability changes quickly, so check the official Bandai sites and reputable toy shops for what is currently on sale.

Tips for new owners

First-time owners do best by setting the clock accurately, since the pet's sleep and meal schedule follows the time on the screen. Keep the toy where you can hear it, and learn what each icon means before the first night. A short check every hour or two during the day is usually enough for most versions.

Do not worry if the first pet does not survive. Early deaths are a normal part of learning the rhythm of care, and restarting is part of the design. Many owners keep a note of what they fed and when, which helps them raise a stronger pet next time.

For travelers, a Tamagotchi makes a light and affordable souvenir, but it is wise to buy from established stores. Look for sealed packaging, a clear model name and an authentic Bandai logo, because imitation toys exist. Prices and models change often, so compare options and confirm the details with the seller before buying.

Why Tamagotchi still matters

The toy became a symbol of Japanese cute culture, known as kawaii, and it influenced later pet and character games on phones and consoles. It showed that a character does not need a story on screen to feel real, because care and routine can create the bond. That lesson shaped mobile games, collectible apps and even the way brands design mascots.

The Tamagotchi also sits comfortably beside other Japanese pocket-sized pleasures, such as capsule toys, character stationery and keychains. These small objects are cheap, collectible and easy to carry home, and they reflect a design culture that values charm in tiny things. Visitors who enjoy Tamagotchi will likely find plenty more to love in toy shops and character stores around Tokyo and Osaka.
