Ministries
Sites we build and look after
Each ministry keeps ownership of its own domain and content.
How we work
What a ministry can expect
Design for humans
Congregations, not developers, are the audience. A site should load on an old phone over a poor connection, read clearly in Japanese and English, and not require anyone to be trained to use it.
Wherever Japanese speakers gather
In Japan, yes, but not only in Japan. Much of our work serves Japanese-speaking churches and returnee ministries across North America and beyond.
The ministry stays in control
You own your domain, your content and your decisions. We can hand over a copy of your site whenever you ask, and you can point your domain elsewhere without going through us.
Looked after, not just launched
Sites we operate are monitored for outages, checked to make sure their links and software keep working, and backed up where they hold data. Handing over a finished site and disappearing is not the job.
Donated work, nothing to pay
The development is donated. We also build on services whose free tiers have covered everything we have needed so far, so ministries have not had to pay for hosting either. The only cost a ministry carries is its own domain registration.
