00 ・ Purpose

Purpose of the system

This design system serves three purposes. When a call is hard to make, return here.

01
What we do is clear at a glance
Never end in abstract philosophy — always land on a functional definition and concrete services.
02
Trustworthy as an operating company
A strong black-and-white skeleton and generous whitespace hold the foundation of trust. No gimmicks.
03
Thought and practice stay connected
Philosophy (designing value) and practice (what we offer) connect within the same screen.
01 ・ Design Principles

Design principles

The overall concept is Structured Emergence — value emerges from structure. The color concept is Dissolving Boundaries — crossing domains and dissolving the lines between them, embodied by two opposing colors (Coral / Deep Blue) and the OKLCH gradient where they meet.

Inside a strong black-and-white skeleton sits a gradient where warm and cool dissolve into each other. Boldness is concentrated in one place — the gradient — while type, layout, and motion stay quiet. When color leads, everything else closes with black and whitespace.

Where distinctiveness lives ・ Two Pillars
① The brand gradient
Coral × Deep Blue. Because the gradient can only take points on the line between the two colors, every appearance sits on the same line — consistency is guaranteed structurally. Color is not decoration; it is the brand's statement.
② The Value Flow graphic language
The most memorable signature: Observe→Define→Shape→Test→Update drawn not as a circle but as a loop that inches forward. This is where the gradient appears most symbolically.
02 ・ Color System

Color system — two tiers

Color is two-tiered: a black-and-white structure (the canvas) and two colors plus their gradient (the meaning). Most of any screen (roughly 85%+) runs in white, black, and gray; the gradient appears only in small areas, only at moments where boundaries dissolve.

2-1 ・ Structure tokensFixed — the base of trust
White, black, and gray form the canvas. This never moves; it is the foundation of trust as an operating company.

Always implement with OKLCH interpolation. The midpoint is a vivid purple-magenta #BF64C2. Default sRGB muddies it into gray-purple — killing the moment where boundaries dissolve.

2-4 ・ Why these colors

The neutral gray base secures a fair, flat point of view; on top of it, the two colors tell the story of the business. The moment where “nurture” and “explore” meet aligns, literally, with the positioning of crossing domains and dissolving boundaries.

Coral ── the reef
A coral reef nurtures a diverse ecosystem — the symbol of an organization that grows startup ecosystems.
Deep Blue ── deep sea, night sky
The symbol of exploring unknown territory where light has not yet reached.
Midpoint ── where they meet
Where “nurture” and “explore” intersect: crossing domain boundaries and binding them together.
Neutral gray ── the base
An achromatic base leaning neither warm nor cool — the stance of seeing things fairly, objectively, flat.

2-6 ・ Gradient usage
01

02
Never the default background of cards or buttons
03
No large fills — lines, thin bands, outlines, small transitions
04
Always OKLCH interpolation
05
The endpoints (flat Coral / Deep Blue) may be used alone
2-7 ・ Accessibility
Text is ink or paper by default. Never use Coral or the gradient as body-text color on light backgrounds (insufficient contrast). Deep Blue may be used for small text such as links. Never carry meaning by color alone — always pair it with labels, position, and shape.
04 ・ Typography

Typography — quiet structure

With color (the gradient) carrying expression, type keeps to structure. No serif headings. Three weights: Regular (400) / Medium (500) / Bold (700).

The heading pattern is EN eyebrow + Japanese heading. Four kinds of emphasis, each at minimum area.
Thin Coral underlineMainly inside body text; the text stays ink.
Coral highlightEmphasis on a whole short heading word (warm / action). Text stays ink.
Deep Blue highlightEmphasis on a whole short heading word (cool / structure). Text turns white.
Gradient highlightKey phrases only; never overused. Only here does text turn white.

05 ・ Layout & Spacing

Layout & spacing

A 12-column grid. Keep the surface simple; take whitespace generously. Content max-width ~1200px; text blocks narrower still (~640–720px). Radius stays shallow (0–4px preferred, 8px max). Dividers are hairlines + whitespace. No drop shadows.

06 ・ Graphic Language

Graphic language — five geometric primitives

No abstract CG, no AI-ish spheres. Five geometric primitives form one consistent symbolic system, and color rides on them. The base is ink hairline; only the signature Update Loop takes the brand gradient.

Value Line
The flow where value starts to move. Ink hairline by default.
Node
Origins and connections. Ink or an endpoint color (Coral / Deep Blue) as a dot.
Frame
Enclosing undefined value to give it meaning. Hairline rules; one endpoint color only for emphasis.
Layer
Layered contexts. Coral and Deep Blue overlap; where they meet, the gradient.
Update Loop
Where the brand gradient appears most symbolically. The signature.
Signature
Nurture → Explore ・ Coral → Deep Blue

Update Loop — the loop that moves forward

Never an ordinary PDCA circle. Drawn as a spiral — a flow that inches forward. The loop's path (the Value Line) is drawn in the brand gradient (Coral→Deep Blue is the direction of travel: nurture→explore); the phase nodes and labels sit quietly.

07 ・ Components

Components (Scope 1)

Don't multiply UI. A small set of patterns, reused.

Anti-template principles: no accent bars on card tops / shallow radius (0–4px) / hairlines + whitespace over boxed containers / CTAs never “color band + solid button.”

08 ・ Motion & Guardrails

Motion & guardrails

Principle: help understanding, don't surprise
Adopt: text rising quietly / lines extending slightly / dots connecting / the process advancing on scroll (the Update Loop's gradient drawing in) / light responses on CTAs. Respect prefers-reduced-motion.
Motion to avoid
Heavy parallax / rotating 3D / AI-ish particle effects / fast transitions / meaningless hovers. With color as the signature, motion stays restrained.
What not to do
The look to avoid
The countermeasure
Pop / childish (large, equal fills of the two colors or the gradient)
Small areas, one lead per screen, black nearby, whitespace to close
Looks like an AI vendor (cyan/teal, the stock blue→purple gradient, dark bg × glowing UI)
No cyan/teal; gradient starts warm (Coral); no glow, small areas
Tech-startup template (color band + solid CTA, top accent bars, deep radius + shadow)
Editorial cues, hairlines, shallow radius; quality of whitespace and type
Looks like a design studio (color loud, business language weak)
Strengthen the language of services, process, and offerings
Colors look scattered (a different color per element)
Fix the palette at two colors + the gradient; identify by number, heading, whitespace
Muddy midpoint (gradient in default sRGB)
Always linear-gradient(in oklch, …)
Poor readability (Coral/gradient as body text color)
Text stays ink/paper; color only in fills, lines, shapes, small labels
Generic AI-generated design (cream × serif display, handshake stock photos)
No serif headings; photos observational, low-saturation
09 ・ Bilingual ・ JP / EN

Bilingual policy

Japanese leads; the English is never a word-for-word translation. The English keeps the canonical core of meaning as a minimal company introduction — naturally signaling readiness for global-facing projects without overplaying the global firm impression.

Temperature of the English
Keep to “Tokyo-based,” “works with international partners,” “supports global-facing projects.” No exaggeration.
Typesetting
Language switch in the Header. Latin type unified on Inter so the typographic center of gravity holds across JA and EN.
Shared assets
The English eyebrow labels and the color system (two colors + gradient) are shared assets, consistent across both languages.
