For individuals and businesses

Your first website, built from scratch, free.

Founder-led website creation for individuals and businesses alike. The first project costs nothing when it is published on a free subdomain.

Simple sites and landing pages / first project, no custom domain / prices incl. tax

First one free

The first project is free when published on a free subdomain (e.g. yourshop.pages.dev), hosting included on a free tier. One free project per customer (the same business or operator); a duplicate claim under a different name is billed at the standard rate. A custom domain is billed at cost. Later projects are JPY 0–11,000 incl. tax (about US$0–75). Add-on features such as photo uploads are JPY 5,500–11,000 incl. tax on top. The free first build may end once the limited number of slots is filled.

Build your first site free See the eligible scope

For a small start

Not a free site builder — a site built for your content

This is a custom development service for people who want someone to build the page, not a self-service free website builder. We clarify the goal and content together, then launch the smallest useful version.

Small business

A basic page for a shop or business

Publish the service, contact details, and reasons to trust the business in one clear place.

New service

An introduction page for a new service

Launch a focused first version, learn from the response, and improve it later.

Landing page

A simple product or campaign landing page

Keep the message and contact path on one page when a quick launch matters.

Use cases

Start from what you need

What goes on the page — and how it is arranged — depends on what it is for. Start from whichever is closest.

Works

Sites I have actually built

Words alone make it hard to picture the result, so here are sites that are live right now. Both open the real thing.

Product site (landing page, blog, FAQ)

UreyukiBox

A landing page that shows who it is for and where to install within the first screen, plus a migration guide, blog, FAQ, and changelog so search visitors can keep reading. Bilingual (JA/EN).

Own product — planning, design, build, and operation

Pre-launch landing page with a sign-up form

DenchoBox

A landing page that announces a product before launch and collects sign-ups. It narrows the pitch to three points and states pricing and timing assumptions on the same page.

Own product — planning, design, build, and operation

Open the live site

These are Mumu Labo’s own product sites: planning, design, build, and post-launch operation were all handled by the founder. Client sites will be added only where permission to publish has been given.

Scope & price

What the free first project may cover

The quote depends on the content, required functionality, number of pages, and how ready the assets are. I propose a scope that fits a simple website or landing page rather than pricing by page count alone.

Within this scope

First one free

Simple sites and landing pages / first project, no custom domain / prices incl. tax

  • Clarify the goal and content Define who the page is for, what it needs to say, and the main contact action.
  • Shape the structure and draft copy Turn the information you provide into a clear reading order and practical first draft.
  • Build for mobile and desktop Implement a static page that remains readable on phones as well as larger screens.
  • Check the page for launch Verify display, links, and basic search information, then support launch within the agreed scope.

Beyond this scope

Work quoted separately

  • Multi-page sites, complex visual design, or ongoing content updates
  • SaaS products, booking, payment, membership, dashboards, and other web-app features
  • Shopify, e-commerce, automation, AI features, APIs, and external integrations
Separate in both cases Domains, hosting, paid themes or assets, and other external service costs
Optional Add-on features such as photo uploads: JPY 5,500–11,000 incl. tax

Why affordable

Why the price can stay low

The approach reduces overhead and scope, not the need for clear communication or quality checks.

Founder-led

Work directly with the founder

There is no separate sales or management layer between the conversation and implementation.

AI-driven

A more efficient workflow

AI supports design, implementation, and checks while the founder remains responsible for the goal and quality.

Focused scope

Build only what launch needs

Start small and prioritise the information and contact path needed for the first release.

Process

From first conversation to launch

You can start with a rough idea; defining the goal is part of the process.

  1. 01

    Discuss

    Share the goal, content, timing, and budget.

  2. 02

    Scope and quote

    Receive the included scope, exclusions, external costs, and final price before work starts.

  3. 03

    Build and check

    I implement the agreed page and check it on mobile and desktop.

  4. 04

    Launch and improve

    I support launch and quote separately for later changes or improvements when needed.

FAQ

Questions about the free first website and pricing

What “free” actually covers, and how custom domains are handled.

Can you really build a website for free?
Yes. The first project is free when the site is published on a free subdomain (e.g. yourshop.pages.dev). Hosting runs on a free tier, so your cost is zero. Only a custom domain is billed separately, at cost. The free build is limited to one per customer, and a phone number is required with the enquiry so it can be confirmed. The free first build may end once the limited number of slots is filled.
What will my URL be if the project is free?
A free subdomain such as yourshop.pages.dev or yourshop.vercel.app. If you want a custom domain (e.g. yourshop.com), registration and renewal are billed at cost. A domain you already own can be used instead.
Can I commission a website for JPY 11,000 or less?
The first project is free. After that, a qualifying simple website or landing page is individually quoted within JPY 0–11,000 incl. tax. Multi-page sites, SaaS products, booking or payment features, Shopify, automation, AI, and API integrations use the standard custom quote instead.
Can you issue a qualifying invoice (インボイス)?
I issue invoices and receipts, but I am not registered as a qualifying invoice issuer under Japan’s invoice system, so I cannot provide one carrying a registration number. Please confirm before ordering if you need it for input tax credit. All listed prices include Japanese consumption tax.
Are domains and hosting included?
Hosting is included on a free tier. Domains are not: registration and renewal are billed at cost. Paid themes or assets and other external services also cost extra, listed separately before work starts.
Can I ask for help before the copy and structure are ready?
Yes. We can clarify the audience, message, and page structure together. The quote depends partly on how ready the copy and images are.
Can I request changes after launch?
Yes. The initial quote distinguishes included work from later additions. Ongoing updates and larger feature changes are quoted separately.
