Junkan Zukuri Co., Ltd. (Headquarters: Nagoya City, Aichi Prefecture; Representative Director: Masashi Hamatani) will officially launch 'Compospet' on Tuesday, April 14, 2026, on the official Compospet EC site. This digital compost allows users to enjoy the process of turning household food waste into compost alongside a digital pet on a smartphone app.
Composting is the process of breaking down food waste using microorganisms to create fertilizer. Compospet changes the previously difficult analog composting into an exciting experience like 'raising a pet' through the power of sensors and an app. It is a new form of compost. To commemorate the official launch of this service, we are also starting a promotional sale offering half-price monitor rates for the first 10 customers.
[Development Background]
Composting is environmentally friendly; simply putting food waste into a base material allows microorganisms to break it down. While home composts are spreading due to rising environmental awareness, conventional home composts faced issues such as 'not knowing how to do it', 'worries about odors and bugs', and 'not knowing the condition'.
'Compospet' eliminates these barriers with the power of technology and characters. We propose a new way to enjoy composting with the combination of 'Compost x Digital Pet'. Sensors are installed in the compost to manage data via a smartphone app, and based on that data, you can 'raise the compost' with your digital pet. 'Compost like a pet'—that is 'Compospet'.
Having received a lot of support in a 2025 crowdfunding campaign, we are finally ready to begin general sales.
[Product Features]
1. Guided by unique digital pets
Characters like 'Volvox-kun' the compost advisor, 'Mikazukimo-kun' who loves music, and the close trio 'Ikadamo-kun' appear in the app to help you grow your compost together.
2. 'Visualization' and advice via sensors
Sensors placed inside the compost measure moisture content and temperature in real time. The smartphone provides advice on 'what the compost needs right now'. You can also keep records of compost temperature changes and the food waste you put in.
3. Safe for indoors, photocatalyst breaks down odors
By applying a photocatalyst to the inside of the main unit, unpleasant odors are broken down. There is no emergence of bugs attracted by odors, making it safe to use in apartment and condo kitchens.
[What Junkan Zukuri Co., Ltd. Aims For]
In today's consumer society, many people are contributing to massive consumption without realizing it. In particular, food waste generated in daily life is disposed of as combustible garbage, but 80% of food waste is water, meaning enormous energy and costs are spent just to burn water.
Composting breaks down food waste into fertilizer. Using that fertilizer for kitchen gardens and gardening creates a small cycle within the household. A small cycle in daily life provides an opportunity to reconsider past consumption. And it gradually influences other consumption as well. However, this is hard to spread solely relying on individual environmental awareness.
Therefore, we offer 'Circulation x Fun' as a new experience. 'Compospet' is the first step. Fun is a propellant that attracts interest in new things.
By creating 'small cycles' with fun at the forefront, Junkan Zukuri Co., Ltd. aims to bring about changes in people's lifestyles and consciousness.
