MKUltraman
IT support and administration for businesses in Japan
I help you see what you've got, run it well, and grow from there, at your pace.
Japan, 2026
Cybersecurity Tracker
Supply-chain breaches in Japan: who was named, which vendor was involved, and when the notice was published.
Domain Exposure Check
See what attackers see about your domain.
Email authentication (SPF, DKIM, DMARC), registrar and DNS, website headers, PHP version, vendor breaches from the tracker, and a breach check for up to three email addresses. Full report for one domain, ¥5,000 + tax.
Your people and your tools form a complex system.
Seeing how it runs is the first step to running it better.
Customer inquiries, bookings, payments, files, and internal handoffs move through the tools your team uses every day. Those tools, the people who run them, and the work that passes between them shape how the business actually runs. Understanding that system more clearly is the best path to optimization.
MKUltraman is the IT support and administration practice of Matt Ketchum, an independent consultant working in Japan since 2009 and based in Tokyo, serving small and mid-sized businesses in English. I look after the everyday IT a company runs on: user accounts and access, Google Workspace or Microsoft 365, email and domains, the website on whatever platform it already uses, the software staff open each morning and the vendors behind it.
The work is organized as five stages. A Decision Session talks through one IT decision in 45 minutes. Diagnostics produces a written assessment of your tools, ownership and risks. Digital Baseline is a one-time setup that puts accounts, access and systems in order. Ongoing Stewardship is a monthly managed IT retainer. Operational Expansion adds new infrastructure, workflows and people to a foundation that already works. Any stage can be the starting point, and every price is quoted in yen plus consumption tax.

About me.
IT administration and digital infrastructure for businesses in Japan.
Fourteen years in Japan have shown me that IT and business gains usually come from retooling, recalibrating, or cleaning up what is already in front of you. You do not need a big new purchase to make big new gains.
The work is the everyday IT a business runs on: accounts and access, email and domains, websites, the software staff use, and the vendors behind it. For a Tokyo executive events network, I built and maintain the website, domains, email, event and ticketing systems. I also advise a holiday-home operator, a tour company and a software developer, all in Tokyo. Client names stay off this site; case studies are available on request.
Selected work
Anecdotes from across my Japan operations.
-
Executive events network
A private community for foreign executives leading Japan operations. Membership, events, and invitations need a site and supporting systems that keep the community running while the founder stays free for the work only they can do.
Developed new revenue streams and introduced new payment solutions, with business-development deals negotiated on their behalf and a better booking platform.
-
Coaching practice
Leadership coaching for founders and executives across Japan and abroad. Positioning, booking, and follow-up stay clear so the practice can grow while the calendar supports the work.
Grew monthly site traffic sixfold and generated at least four additional hot leads per month.
-
Research and commentary
A Tokyo-based scholar writing and speaking on international affairs. The public site stays current and light to maintain, so the work stays on research, events, and commentary.
Catalogued and digitized over twenty years of multilingual publications on international affairs.
-
Technology product company
A Tokyo software developer with decades of products, each with its own site. I work with the company on digital strategy, web consolidation and how its products are presented online.
Mapped and improved the workflows of paying clients on their platform through hands-on platform debugging and workflow analysis.
