Services
Build it, grow it with AI, run it for the long haul. Webharu’s services rest on those three pillars. Production only, operations only, operations picked up midway — start anywhere, take only what you need. Choose what fits the phase you are in.
Before we build, we decide what “done” looks like.
Most inquiries begin with “we don’t know what to ask for.” So the first thing we do is not an implementation estimate, butdeciding the completion criteria. We put the purpose, the audience, the priorities and the state that must be reached into a document. Because that is settled, we can promise tokeep the agreed price unchanged after work begins and keep working at no extra cost until that state is reached.
The Requirements Definition Phase (from¥100,000)is also available on its own. If you go on to the main contract, the full amount is credited toward it (effectively free); if you don’t, the documents are still yours, and we refund the full amount for any reason if you tell us within 30 days of delivery.
Start with requirements definition See pricingBuild it. Grow it. Care for it.
Web agencies tend to stop at “built and delivered.” We take it end to end: requirements definition before the build, growth with AI after launch, and operations for as long as you need them. Which is why the person in charge never changes mid-project.
BuildDESIGN & BUILD ─ Websites and apps
Websites, apps and internal systems alike. From designing precisely in Figma and building it out in Webflow, through to building at the speed of AI. We take brand building past the “pretty site” stage and give it a build that holds together.

GrowGROWTH ─ Content production
Content operations that stack up results after launch. We hand over exactly the method we proved on our own blog, which drew roughly 190,000 search impressions in the past 12 months. Designed to satisfy SEO and LLMO at once, with our founder editing every piece to hold up E-E-A-T.

CareSUPPORT & AI ─ Operations and AI adoption
Launch is where it really starts. Updates are just an email; post to Instagram and the news section updates itself — with our own operations platform and AI, we support operations and improvement long after launch.
See AI adoption support01 Build ─ it isn’t only websites.
These are things our founder has actually built together with AI (Claude Code) on this one computer. Not just websites: apps and internal systems come out of the same setup. Every one of them exists.
Corporate and service websites
Original design, drawn in Figma and built out in Webflow.
Examples: JTB Americas / Ibuki Clinic / SnugAI Website Production
As fast as 1–2 weeks. SEO, AIO and fast rendering as standard.
Example: this very siteLanding pages
Single-page pieces for campaigns, products and events.
Examples: an event LP hosted by Nippon TV / RobopoiiOS apps
From concept to App Store release. Three of our own apps are live.
Examples: Sati / Token Map / BooketWeb platforms and internal systems
Web systems with form intake, automatic notifications and an admin screen.
Example: our own operations platform (running in production)API & MCP Development
We put your own systems into a state where AI can operate them directly.
Example: our own CMS API and MCP server (documentation published)Owned media and CMS
Submission, categorization and multiple languages — the whole machine for growing content.
Example: a 55-article journal with English and Korean editionsInternal tools and automation
Calculators, automated inquiry handling, routine work moved onto AI.
Example: a calculator for the transitional measures of Japan’s invoice systemDesktop apps and more
Internal tools that run on a Mac — we build outside the web, too.
“Can you build this?” — just ask us firstIf it isn’t listed here, we can usually still build it.Contactus and tell us what you want built, in your own words.
02 Grow ─ we prove it on ourselves first.
Both SEO and AI search optimization (LLMO) are tested on our own site first; we only offer what the numbers back up. Every figure below is measured on this site.
(measured in Search Console)
(measured in Search Console)
55 Japanese articles, every one edited by our founder
Scored by third-party tools (measured 2026-07-28, on this site)
- Lighthouse SEO 100 · Accessibility 100 · Best Practices 100
- SSL Labs A+ (transport security)
- Mozilla Observatory A+, 105 points (security configuration)
- W3C Validator 0 errors (HTML quality)
These are free scoring tools published by Google, Mozilla and others, so anyone can check the same numbers. We run the sites we build through the same standards before delivery.
03 Care ─ launch is where it really starts.
We don’t build it, hand it over and walk away. Sites Webharu builds can have our own operations platform embedded in them. Removing the labor of updating, improving against the numbers, and an AI that has learned your business supporting the daily running of it — all of that is part of the service.
Updates: just send an email
“Fix this sentence,” “swap this photo” — send an email and our founder and AI apply it quickly. You never have to learn an admin screen.
Just post to Instagram
On supported plans, posting to Instagram updates the news section of your site automatically. Our own operations platform removes the double-entry work.
We read the numbers and propose the next move
We check Search Console and GA4 regularly and propose what to do next. The gap between a site left as built and a site being grown opens up right here.
We train an AI on your business
An AI that knows your products, your track record and your tone of voice helps with article drafts, inquiry handling and routine work — assembled company by company. As AI adoption support, you can start with one small automation.
Packages and pricing.

|---|---|---|---|
| Who it is for | Corporate, recruiting, landing, hotel and medical sites — anything that needs design and structure | Businesses that already have a site and want SEO content to bring in traffic and inquiries | Businesses that want AI built into site operations — articles, images, routine work |
| Suits you if | You want to settle in with a company that knows Webflow and current technology well | You have no time to write, and want to keep publishing without losing quality | You want operations off your hands, or a setup where updates run in-house |

For the three worries every buyer has.
People trip over the same three things when commissioning web work. We answer each one head on.
① You can see who is building it
From the first conversation through requirements, design and post-delivery operations, our founder stays on it to the end. The trade name, the location and the founder’s face are all public. Nothing is handed to anonymous subcontractors. So conversations move fast, and responsibility is never in doubt.
② Documents your approval process can use, and the reasoning behind the price
Company profile, quotes by scenario, the reasoning behind the price, a portfolio and the process — handed over as one set of documents you can circulate internally as they are. You get them in a state where you can explain why the number is what it is.
③ We lead the project
We don’t hand requirements definition back to you — we do it for you. With frequent progress updates and meetings at every milestone, we set the schedule, so the project moves even when you can only give it part of your attention.
What we promise about process, and where we flex.
- First reply within one business day.We respond to your inquiry before anything else.
- We share anything that needs confirmingas it comes up.
- Regular progress reportsmean you never lose sight of where things stand.
- Meetings at every milestonekeep everyone aligned.
- For content operations, a monthly reportshares the results and the next move.
- We lead the project management— we handle the scheduling.
Join partway, take only what you need.
Production only, operations only, or operations picked up midway — all are possible. There is no minimum contract term. You can combine just the services your current phase needs, without strain.
The first step to getting this right.
