Sakupa's Water plan currently costs ¥200 per month for one long-term website, with 100MB of storage, 2GB of monthly transfer, and 20,000 monthly requests. Those numbers describe hosting limits. They do not include site creation, AI tools, domain registration, email, forms, booking, or payments.
Sakupa is developed by the author. This checklist makes the product claim testable before a company site is published.
1. Inspect the production artifact
For a static Next.js site:
npm run build
du -sh out
find out -type f | wc -l
find out -type f -size +1M -print
Do not upload the project root. Publish only the reviewed static output. Stop if it contains .env files, credentials, customer records, unlicensed source images, or other private material.
2. Measure a representative page
Use browser developer tools or an automated page check to record transferred bytes and request count on a cold load. Repeat on the image-heavy page, not only the home page.
A 1MB page with ten requests suggests roughly 2,000 complete cold loads before either monthly limit becomes relevant. It is only a rough estimate because caching, crawlers, repeat visits, and page variation affect usage.
3. List excluded services
Create separate budget rows for the domain, business email, form processing, booking, payments, AI tools, and maintenance. Record free-tier limits and who receives billing alerts.
4. Define the failure response
The plan does not upgrade automatically. Over-limit sites may receive a notice or service restriction. Decide whether the response is to optimize assets, move a large download elsewhere, upgrade manually, or pause a campaign.
The plan fits when the site is static, small, and operationally allowed to stay within explicit limits. A low price is not a substitute for measuring the build and assigning an owner.
