These budget smartwatches are the first in Japan aimed specifically at adults, despite the longstanding popularity of Hello Kitty merchandise since 1974.

Priced at 14,080 yen (approximately $93), the smartwatches are currently available exclusively in Japan through the Green House store.

The smartwatches are rated IP68 for water and dust resistance, making them suitable for fitness enthusiasts, and they are compatible with both iOS and Android devices.

Supporting 13 languages, including English, these smartwatches can be purchased by international fans through platforms like eBay.

Equipped with a 1.83-inch TFT display that boasts a resolution of 240x284, these devices can track heart rate, daily steps, and blood oxygen levels across 20 different workout types.

Users can enjoy notifications and alerts delivered in the voices of their favorite Sanrio characters, and the watch straps feature adorable character faces.

On February 20, 2025, Green House launched a new line of smartwatches in Japan, featuring designs based on iconic Sanrio characters such as Hello Kitty, Kuromi, Cinnamoroll, and Pompompurin.

The smartwatches are designed for convenience, with a battery life that lasts about a week and a dedicated CharaLife app to help track the device if it gets lost.
