The challenges of home automation in Japan,
solved by Formetra

  1. Challenge 01

    Recreating the automation you know from abroad in a Japanese home

    Bringing the features and ease of use you are accustomed to overseas into a home in Japan takes broad expertise — from integrating multiple protocols to a deep understanding of Japanese architecture, electrical work and residential equipment.

    How Formetra helps

    Specialist expertise,
    delivering your ideal automation

    We combine multiple protocols and design the optimal configuration around Japanese building equipment and electrical requirements — taking the experience you are used to abroad as the baseline, and making your home even more comfortable.

  2. Challenge 02

    Complex coordination across architects, contractors and equipment suppliers

    Lighting, air conditioning, curtains and other systems are often handled by different companies, and pulling together how everything connects — and who is responsible for what — can be a heavy burden.

    How Formetra helps

    One specialist point of contact
    for all coordination

    We handle technical coordination with Japanese architects and contractors, and take charge of your home automation from design and build through commissioning and handover.

  3. Challenge 03

    Language barriers make communication difficult

    Communication with Japanese design and construction teams happens mainly in Japanese, often with a lot of technical terminology. Projects can move ahead before your preferences for controls and the way you want to live are fully understood.

    How Formetra helps

    Listening in English,
    turning it into clear specifications

    We carefully organize your wishes in English and share them with the Japanese design and construction teams, confirming how you want to control your home as we turn it into a working system.

  3. Step 03

    System design

    Finalize the specs

    We define the equipment, control and network specifications, and share wiring and connection requirements with your architect and contractors.

  4. Step 04

FAQ

Frequently asked questions

Have another question? Feel free to ask when you get in touch.

Contact us
Can I consult you from overseas?

Yes. We work through online meetings, sharing drawings and control concepts so you can review the specifications from abroad. You are welcome to consult us even before drawings or equipment are decided. We work in both English and Japanese.

Can I still work with you if my architect or contractor has already been chosen?

Yes. We work with your architect and contractors and take charge of the home automation scope. You can contact us directly or through your architect.

Can you use the equipment I use overseas, or a brand I prefer?

Tell us the model numbers and how you would like to use them, and we will check the conditions for use in Japan and how they can connect to and be controlled with the other equipment. If something is not compatible, we will propose the closest alternative.

How are fees determined, and what support do you provide after handover?

We quote based on the number of devices, the integration scope and the extent of fabrication and tuning, shown separately from on-site construction costs. Post-handover contact, support scope, method and fees are agreed in advance for each project.
