A landing page you can keep improving — Suiteki Sekisen: steady drops pierce the stone
The copy you wrote today, live within 48 hours. — Learning without doing ends here.
That headline you wrote at the seminar — still sitting in your notebook? Apply what you learned in the same month, and next month learn how many people saw it. Keep your current website as it is. Hold one extra page to test your learning — you have nothing to lose.
No setup fee. Start price 19,800 yen/month for 12 months from contract (development start) → then 9,900 yen/month forever (tax excluded)
A limited price means limited slots — we take just two builds a month (members and non-members combined).
No lock-in — cancel anytime. If you leave, the whole LP is handed over to you.
For companies in Kumamoto only. Meeting in person — at your site, with the real thing — deepens understanding and lets us build in less time.
Act 1 — In the car after the seminar
"I want to fix this part of our website."
In the car on the way home, your notebook holds a rewritten headline and three things to fix. With every seminar, "what to fix" gets more concrete.
Monday morning, you open the notebook and realize — there is nowhere to put this copy.
What you learned is right. What was missing is a place to apply it.
Act 2 — Sound familiar?
You learned. But it never went live.
- Every seminar adds another "I want to fix this on our site"
- But asking the web agency means a quote, weeks of waiting, tens of thousands of yen — so you stopped asking
- You saw the renewal quote and quietly closed it — the site is still as it was at opening
"I learned, but nothing changed." — The fault is not yours. You simply had no place to apply it.
The turn — the real culprit
The villain is not a vendor — it is a fee structure built on "build and forget".
Web agencies are not evil, and neither are budget subscriptions. The fee structure itself — "deliver and done", "the monthly fee only covers upkeep" — was never designed for continuous improvement. That is why every fix needs a quote, why the monthly fee never goes down, and why the site disappears when you cancel.
When you want a change
- One-off build (300–600k yen)
- Quote each time, weeks, tens of thousands of yen
- Budget subscription (5–10k yen/mo)
- Upkeep only (no improvement)
- Suiteki Sekisen
- Monthly update batch — swaps in 48 hours, page additions too

- Suiteki Sekisen

The freedom of a one-off build, plus the lightness of a subscription. Monthly-only, endlessly fixable, and yours even after you leave — that is Suiteki Sekisen. Nothing to lose.
THE NAME
Suiteki Sekisen — steady drops pierce the stone.
“Suiteki Sekisen” (水滴石穿) is an old four-character proverb: a small drop of water, falling without pause, eventually pierces even hard stone. That proverb is where this plan takes its name.
Each monthly update batch is one drop. The headline you rewrote at a seminar, a swapped photo — small drops. They keep falling, month after month, and the monthly report shows the mark they leave. One day, there is a hole in the stone.
So no — we do not move in a rush. One sure drop every month.
The guide — a builder of systems, Japanese spirit with modern craft
Honestly: I am not a designer.
Kentaro Ichihara
CEO, Nexa Engineering Inc.
I am an engineer — 15 years at Panasonic in battery production equipment and production systems, through the launch of a joint plant with a leading North American EV maker in Nevada. I will not win design awards.
What I sell instead is speed, numbers, and technical quality. AI-driven development is why a zero setup fee, a first draft in 3–5 business days, and 48-hour fixes are possible — which means that at this speed and this price, we can keep up with your trial and error, month after month.
The proof is real artifacts: my business card, this very LP, our own sales ledger (SFA), and our LINE AI reception — all self-built the same way and in daily use. We build your page with the same craft.
* We search for “Kumamoto sales systemization” (in Japanese). Results change daily — see with your own eyes.
Technical quality included in every plan
- Mobile-optimized, responsive
- Page speed (Core Web Vitals)
- Optimized for search and AI search (structured to be cited by ChatGPT and others)
- Readable on old devices and slow connections
- Accessibility such as reduced-motion support
When you are ready for full-scale design, graduate to a design agency — and take the LP with you, code and all.
The system — how learning completes a loop
Learn → try → numbers → learn again. One loop per month.
Learn
Collect the copy you wrote at seminars and the words you want to test.
Try — the monthly update batch
Submit everything by the deadline: swaps go live within 48 hours as a rule, and adding or reworking sections (blocks within the page) and pages takes up to a week. Each update batch is one “drop.”
Numbers — the monthly AI report
How many people visited, where they stopped reading, how many inquiries came in — one page, every month.
Learn again
Attend the next seminar with your own numbers. Hypothesis → experiment → result finally completes a loop.
The change — what this one page brings
Three changes this one page brings.
Published within the month
Copy you write goes live within 48 hours of the monthly update batch, as a rule — out in the world the month you learn it.
Numbers next month
"How many people saw it" arrives as a one-page AI report. Even a miss becomes the number you learn from next.
Yours even after you leave
The full LP is yours. No upfront cost, no minimum term. Even a short run leaves you far ahead of learning without doing.
* 48 hours counts from the monthly update-batch intake.

Report within 3 business days
A one-page report on how your site looks on mobile, how fast it loads, and how it appears in search and AI search. Stopping at the check is fine — no sales calls. If you sign up, the first draft arrives in 3–5 business days.
The outcome
"Learning without applying" ends here.
The headline you rewrote at the seminar is live within the week. Next month, a one-page report tells you how many people saw it. You attend the next seminar carrying your own numbers.
You will keep finding things to fix — and that is fine. Now you have a place and a means to apply them.

- All prices exclude tax. No setup fee.
- The 12-month start-price period counts from the contract (development start), not from launch. Larger builds take time to develop, so the page may not go live immediately.
- No lock-in: no minimum term, cancel anytime (end of month).
- On cancellation the full LP (code, images, copy, analytics data) is handed over free. The domain is in your name from day one.
- Domain fees (registration and annual renewal) are billed separately at cost. You can register the domain yourself (recommended — just point the nameservers to our host) or have us register and manage it for you. Either way, the registrant is you from day one.
- Production intake: two companies a month in total — the limited price exists because we keep the number small.
Everything included as standard
- Full build
- Hosting & SSL
- Domain management (in your name)
- SEO & AI-search optimization
- Analytics + monthly AI report
- The monthly update batch
* The only at-cost extra: domain fees (registration and annual renewal).
Two optional packs are available — LINE AI Reception and Multilingual (all with no setup fee; start price for 12 months, then half from month 13). Note: AI replies in LINE AI Reception come with a separate AI usage fee (the API cost), billed at actual cost — pay it directly yourself or have it added to your monthly bill (typically a few hundred to a few thousand yen per month for a small business). See full pricing and pack details →

FAQ
Honest answers to common worries.
What is Suiteki Sekisen?
A landing-page build-and-run plan you keep for a monthly fee only — no upfront cost. Send your edits in the monthly update batch and they go live within 48 hours as a rule, and an AI report tells you every month how many people viewed the page. Starter price 19,800 yen/month (excl. tax, 12 months from contract), then 9,900 yen/month forever from month 13. No minimum term; on cancellation the full LP is handed over free, and the domain is in your name from day one. Provided by Nexa Engineering Inc. in Kumamoto, Japan, for companies in Kumamoto Prefecture.
What happens to the LP or site if I cancel?
It does not disappear. The full set — code, images, copy, analytics data — is handed over free. The domain is registered in your name from day one, so the URL stays too. The same applies even if you cancel after one month.
What happens to my current website?
We do not touch it. Your current site stays as it is; we build one extra LP beside it for testing what you learn. The domain is newly registered in your name, or a subdomain if you prefer.
Will this upset my current web agency?
No. We do not touch your existing site, so there is no conflict with your maintenance contract. And when you are ready for full-scale design, graduate to a specialist agency — the LP goes with you, code and all, with handover notes.
How much can I ask for each month?
Everything from swapping copy, photos, buttons and prices, to reworking or adding sections (blocks within the page), to adding pages. Submit requests together by the monthly update-batch deadline. There is a monthly guideline, but going a little over it never gets a flat no — just send it in with your update batch and we will sort it out together. See the monthly volume guideline →
Is it really monthly-only?
Yes — production and operation are monthly-fee only. No upfront cost; 19,800 yen/month for the first 12 months from contract, then 9,900 yen/month forever (excl. tax). No surprise invoices — only requests beyond the monthly update-batch guideline get a quote in advance. The only at-cost extras are domain fees (registration and annual renewal) and, if you use the optional LINE AI reception pack, its AI usage fees — both explained before you sign.
How should I prepare the domain?
We recommend registering it under your own registrar account. We guide the setup and you only point the nameservers to our host — we never hold your account, and on cancellation you simply point them back; there is no handover procedure at all. If that feels difficult, we can register and manage it for you: the registrant is you from day one, you pay only the actual domain cost, and on cancellation we hand it over by account transfer or by issuing the AuthCode. Either way, the domain is yours.
Can companies outside Kumamoto apply?
We serve companies in Kumamoto Prefecture only. Meeting in person — at your site, looking at the real thing — deepens understanding and lets us go from interview to launch in less time, at this price. We currently do not take online-only engagements.
Is there a benefit for Okage Juku members?
Yes. Paid members of Okage Juku can use the Suiteki Sekisen LP — both production and monthly upkeep — free of charge as a member benefit (the intake is two companies per month in total, shared with non-members). Non-members are welcome at the regular price, and the free speed diagnosis is free for everyone.
Peace of mind — one last time
Three assurances for those who cannot afford to fail.
The diagnosis can be the end
After the free speed diagnosis, no sales calls. Receiving the report and stopping there is perfectly fine.
Zero upfront cost
No minimum term either. You stay light — starting and stopping alike.
The domain is in your name
Registered as yours from day one. When you want full-scale design, graduate to a specialist agency, LP and all.
Shall we publish that copy in your notebook — this month?
The steps are as above: add us on LINE and send your current website URL. Within 3 business days you receive the free speed-check report. Stopping at the check is fine — no sales calls.
