Why KomuraSoft Builds Websites on the Digital Agency Design System — Low Cost and High Quality Can Coexist

The design phase accounts for a large share of most website-production quotes. KomuraSoft compresses that phase by building on the design system published by Japan’s Digital Agency — keeping prices down while stabilizing quality.

When people hear “low-cost website production,” most assume quality is being sacrificed somewhere. And in fact, cutting price by skipping the discovery interviews or just pouring text into a template tends to produce sites where nobody can tell what the company does.

Our website development service keeps its price down elsewhere: through standardization of the design phase. This article explains what the Digital Agency design system is, why it lowers cost, why quality doesn’t suffer, and which projects it is not a fit for.

1. What the Digital Agency design system is

The Digital Agency design system is a published standard for the design of Japanese government websites and applications. Roughly, it defines:

The important point: it is published under an open license and usable on private-sector sites. Government-service sites must work for everyone regardless of age, environment, or IT literacy, so contrast, type sizes, and ease of operation are designed with verification behind them. A private company site can build directly on that accumulated work.

Note that using it does not grant any certification or approval from the Digital Agency. We are not “Digital Agency certified” — we apply the openly published standard to private-sector sites.

2. Why it lowers cost — the design phase disappears from the quote

A typical website-production quote carries substantial design line items: homepage design comps, subpage designs, revision rounds. When design is produced from scratch, this phase alone can easily run to hundreds of thousands of yen.

Building on a design system changes that structure.

• Colors, type sizes, spacing, and button styles are decided from the start
• The “produce several design candidates, pick one, revise” rounds mostly disappear
• Fewer judgment calls depend on a designer’s intuition, so there is less rework

In other words, the price is lower not because of discounting but because the work itself shrinks. The hours saved go into what actually drives results — a structure that communicates what the company does, the copy, and the inquiry flow. Most of the time, the reason a site fails to communicate is structure, not design, as we wrote in the first three places to fix on a site that doesn’t generate inquiries.

3. Why quality doesn’t drop — it actually stabilizes

The intuition that “less design work means lower quality” assumes from-scratch design. With a standardized design system, the logic reverses.

First, accessibility. The Digital Agency design system’s components are designed with color contrast, type sizes, focus visibility, and touch ergonomics in mind. Guaranteeing that level in bespoke design work costs verification hours on every single project. Using vetted components stabilizes quality as a result.

Second, real-world track record. Government services are operated for an extremely broad audience, from smartphone novices to specialists. The design rules used there were hardened not by “does it look fresh” but by “can anyone use it without getting lost” — which is exactly the property that matters for the prospects visiting a company site.

Third, consistency. A site where button shapes and heading rules drift from page to page is harder to read for that reason alone. Following a design system means pages added later don’t break the structure or tone.

This site itself is built on the design system, and so is our client work: the website renewal for Douzu Carry Service, a transport company in Miyazaki, followed the same approach.

4. Standardized does not mean identical

A common worry: “Won’t a standardized design make my site look like everyone else’s?”

What gets standardized is the foundation — color rules, the type scale, component specifications. What actually determines a site’s impression is the logo, photos, headline copy, page structure, and tone of writing, and those are built from scratch per site. A shared foundation and a lack of identity are different things.

That said, there is something we should be upfront about: this approach does not fit projects that need elaborate custom visuals or animation as brand expression — brand sites or campaign sites where staging a worldview is the core value. Those projects get better results with a specialist design firm and a proper design budget. If your consultation turns out to center on that kind of requirement, we will say so plainly at the start.

5. Summary

• From-scratch design work makes up a large share of website-production cost
• KomuraSoft compresses that phase by building on the design system published by Japan’s Digital Agency
• The price drops because the work shrinks, not because of discounting — the saved hours go into structure, copy, and inquiry-flow design
• Quality stabilizes, because the components are accessibility-minded and proven in live government services
• Logos, photos, and copy are made per site, so sites don’t end up identical — though projects needing elaborate custom visuals are not a fit

Frequently Asked Questions

Common questions about the topic of this article.

Is the Digital Agency design system allowed on private-sector company sites?

Yes. Japan's Digital Agency publishes its design system under an open license, and it can be used on sites outside government. Using it does not confer any certification or endorsement by the Digital Agency, though — we apply the publicly available design system to private-sector sites on our own responsibility.

Won't a standardized design make my site look the same as everyone else's?

Only the foundations are shared — color rules, type scales, component specifications. Logos, photos, headline copy, and page structure are built per site, and those are what actually determine the impression. What standardization does give you is consistency in the parts that should be consistent: readable text, predictable buttons, usable forms.
