A few common questions
How quickly will I hear back?
We aim to reply within two business days. If you write over a weekend or Japanese public holiday, you'll hear from us on the next working day.
What kinds of enquiries do you accept?
Questions about any of our three services, general curiosity about household sustainability in Japan, requests to understand whether our work fits your situation, or feedback about anything on the site — all of these are welcome.
Do I need to commit to anything by contacting you?
Not at all. An initial message is simply the beginning of a conversation. We'll understand your situation, share what might be useful, and leave any next steps entirely to you.
Are you based in Japan?
Yes. Our work is specific to households in Japan, and our on-site visits take place within the country. We have familiarity with regional rebate programmes, local building traditions, and the seasonal considerations that shape how homes in Japan use energy.
