The Tamagotchi Nano (たまごっちナノ) is a Tamagotchi released in Japan in 2010. It is based on the Tamagotchi Mini, Tamagotchi iD, and Tamagotchi iD L. Like the Mini, it was marketed not as a virtual pet, but rather as an accessory for the iD.

In addition to the two main versions of the Nano, it also spun off three licensed variants: the Pocket Usatama, the Gudetama Tamagotchi, and the Eevee Tamagotchi.


The Nano comes in two versions, one based on the Tamagotchi iD, and the other based on the Tamagotchi iD L. It is approximately 66% smaller than said versions, making it bigger than the Tamagotchi Mini but smaller than the iD. It is also round at the back, making it thicker than a normal Tamagotchi. Like the classic Tamagotchi, it takes two LR44 batteries. The back of the shell contains no screws; instead, a pressure-sensitive tab keeps the back plate on, and must be pressed down to open it.


The Tamagotchi Nano has two growth stages; Baby and Adult. The baby stage is 24 hours long, and can die at this stage if it is neglected enough. The Adult stage will continue until it leaves either due to neglect or reaches the end of its life span. Which adult character a baby becomes depends on the series, its gender, and the quality of care it is given. It can also evolve into a secret character if certain requirements are fulfilled.

Like the Mini, there are no on-screen icons, and therefore all information is conveyed through the screen and buttons. If the Tamagotchi needs something, the player can press the C button for an animation to see what it needs. If it needs nothing, it will instead come up close to the screen.

Pressing the A button opens the main menu, with the options to feed or to play the minigame. The A button is also used to clean up Poo or cure Sickness.


The minigame involves catching the letters that spell the word "TAMAGOTCHI" in order. Catching anything else will end the game. The player must successfully spell out "TAMAGOTCHI" three times to complete the game.


If an adult Tamagotchi is neglected enough, it will become downhearted, indicated by it facing away from the screen and three lines appearing at the top right of the screen. The player must press A several times to cheer the Tamagotchi up. won't be able to switch to the clock, turn off the sound, play games or feed until it's cured.

If the player does not treat the downheartedness in time, the Tamagotchi will appear holding a suitcase and leave after a few minutes. In this case, it is too late for the player to intervene, and the Tamagotchi will leave a goodbye note on the screen. Pressing A and C together produces a new egg.



  • This is the only Tamagotchi release to be named and marketed with an English name in Japan.
