Design System Inspiration of Cybozu

1. Visual Theme & Atmosphere

Cybozu (サイボウズ) is Japan's leading teamwork-software maker — the company behind kintone, Garoon, and Cybozu Office — and its design language splits cleanly into two brand-owned worlds that share one philosophy: clarity in service of teamwork. The corporate face at cybozu.co.jp is calm, editorial, and almost civic in tone: a pure white (#ffffff) canvas, dark grey body ink (#333333) set in the classic Japanese Hiragino Kaku Gothic Pro stack at a generous 16px / 32px line-height, and a single confident teal accent (#139cb7) that does almost all of the interactive work. On the homepage that teal appears 446 times as the link and call-to-action color, training the eye to read teal as "the next step." Light teal (#64bdd4) appears as a softer fill and border companion, and a muted grey (#aaaaaa) carries the bilingual English section labels ("News", "Products", "Seminar・Event") that sit quietly above each Japanese block.

The flagship product, kintone (kintone.cybozu.co.jp), runs a deliberately different, design-led identity — Cybozu's open product-design org (the kintone Design System, the kintone-ui-component library, and the long-running Cybozu Product Design Magazine) lives here. kintone's signature is a warm, friendly amber-yellow (#ffbf00) paired with a soft brown-black ink (#231200) instead of pure black, set in a Roboto + Noto Sans JP stack. Its section headlines run large and bold (52px / weight 700) with an unusual positive letter-spacing (+2.6px) — a deliberate airy, approachable cadence that says "anyone can build this," very different from the tight tracking of Western SaaS. Yellow badge chips (#ffbf00) and amber decorative circles (#ffdb4f) punctuate the page with optimism.

What unites both worlds is restraint with depth and a hairline-first separation strategy. The corporate site uses only the softest circular-button shadows (rgba(0,0,0,0.1) 0px 0px 6px 0px); kintone is essentially flat — feature cards are white with a thin #d6d5d5 border at 8–10px radius and box-shadow: none. Sections separate by tint (#f6f6f6 corporate, #f3f3f3 / #fff5e1 kintone) and #e6e6e6 hairlines rather than elevation. The result is a system that reads as trustworthy and unintimidating — Japanese B2B software that takes accessibility and teamwork seriously enough to feel human.

Key Characteristics:

• Corporate teal (#139cb7) as the single canonical accent — links, CTAs, the "action" color
• Hiragino Kaku Gothic Pro stack on the corporate site; Roboto + Noto Sans JP on kintone — real Japanese CJK font stacks captured live
• Dark grey body ink (#333333) corporate / warm brown-black ink (#231200) on kintone — never harsh pure black for reading
• kintone's friendly amber-yellow (#ffbf00) brand with amber-light (#ffdb4f) and deep amber (#ff8f00) accents
• Positive letter-spacing on kintone headlines (+2.6px at 52px) — an approachable, airy cadence
• Flat, hairline-separated cards (1px solid #d6d5d5, 8–10px radius, no shadow) on the product surface
• Bilingual JP/EN section labels with muted-grey (#aaaaaa) English headers over Japanese content
• Soft circular icon buttons with a faint rgba(0,0,0,0.1) shadow as the corporate site's only elevation

2. Color Palette & Roles

Primary (Corporate Cybozu)

• Cybozu Teal (#139cb7): The canonical company accent and primary_color. Link color, text-link CTAs, circular-icon-button glyphs — the single saturated "action" color across cybozu.co.jp (446 occurrences live).
• Teal Light (#64bdd4): Softer companion teal used for fills, accent borders, and decorative blocks.
• Ink Grey (#333333): Primary body and heading text on the corporate site. A dark neutral grey, never pure black for reading.
• Pure White (#ffffff): Page background, card surfaces, text on teal/dark.

Neutral & Surface (Corporate)

• Surface Grey (#f6f6f6): Tinted section background for alternating content bands.
• Hairline (#e6e6e6): Thin borders, dividers, and card outlines — the primary separation device.
• Muted Grey (#aaaaaa): Bilingual English section labels ("News", "Products"), low-emphasis captions.
• Muted Slate (#838d94): Tertiary text and fine print.
• Slate Dark (#31424e): Dark accent blocks and footer-adjacent panels.
• Slate Darker (#465560): Darkest neutral for accent borders and dark surfaces.
• Pure Black (#000000): Occasional maximum-contrast text.

Product Identity (kintone)

• kintone Yellow (#ffbf00): kintone's flagship brand color — yellow badge chips, banners, decorative circles, the optimistic product signature.
• kintone Amber (#ffdb4f): Lighter amber for decorative circles and soft highlights.
• kintone Amber Deep (#ff8f00): Deeper amber accent for emphasis moments.
• kintone Ink (#231200): Warm brown-black — kintone's body and heading text instead of pure black, giving the product a friendly warmth.
• kintone Surface (#f3f3f3): Neutral grey product section background.
• kintone Tint (#fff5e1): Pale warm-cream tint band — the amber brand softened to a surface.
• kintone Card Border (#d6d5d5): Hairline border for kintone's flat outlined cards and buttons.
• kintone Dark (#333333): Dark fill for kintone's primary CTA buttons (yellow/white label sits on this dark surface).

3. Typography Rules

Font Family

• Corporate: Hiragino Kaku Gothic Pro ("ヒラギノ角ゴ Pro W3", "Hiragino Kaku Gothic Pro") with Meiryo / メイリオ / "ＭＳ Ｐゴシック" fallbacks — the classic Japanese corporate gothic stack, used across cybozu.co.jp.
• Product (kintone): Roboto, "Noto Sans JP", "Helvetica Neue", Arial, "Hiragino Kaku Gothic ProN", "Hiragino Sans", Meiryo — a Latin-first/CJK-paired stack used across kintone.cybozu.co.jp.

Hierarchy

Principles

• Two stacks, two jobs: Hiragino Kaku Gothic Pro is the corporate/institutional voice; Roboto + Noto Sans JP is the product/approachable voice. They never swap surfaces.
• Positive tracking as friendliness: kintone's headlines use positive letter-spacing (+2.6px at 52px) — the opposite of tight Western SaaS tracking — to feel open and unintimidating.
• Bold where it labels, regular where it reads: corporate nav is weight 700, body is weight 400; kintone heads are 700, body is 400. Weight, not color, carries most hierarchy.
• Warm ink over black: corporate uses #333333, kintone uses #231200 — never pure black for sustained reading.

5. Layout Principles

Spacing System

• Base unit: 4px / 8px
• Scale: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 62px
• Notable: kintone feature cards use a generous 24px internal padding; corporate sections breathe with ~62px top padding on each block

Grid & Container

• Corporate: centered single-column news/products portal with bilingual section labels; content bands alternate white and #f6f6f6
• kintone: large bold section headings anchor each band; feature/use-case cards arranged in multi-column grids (顧客・案件管理, 脱エクセル, ワークフロー, etc.)
• Cards use 8–10px radius and group related services/use-cases

Whitespace Philosophy

• Editorial calm: the corporate site reads like a civic publication — generous vertical rhythm, quiet bilingual labels, never a hard sell
• Flat segmentation: sections separate by tint (#f6f6f6, #f3f3f3, #fff5e1) and #e6e6e6 / #d6d5d5 hairlines, not by elevation
• Approachable density: kintone's airy headlines + positive tracking keep an information-rich B2B product feeling welcoming

Border Radius Scale

• Small (4px): compact kintone link buttons
• Medium (8px): kintone cards, primary/secondary buttons, yellow chips
• Large (10px): kintone feature cards — the workhorse
• Full (9999px / 50%): corporate circular icon buttons

6. Depth & Elevation

Shadow Philosophy: Cybozu is a near-flat system. Live inspection found box-shadow: none across kintone's hero, feature cards, and outlined buttons; the corporate site uses elevation only on small circular icon buttons (rgba(0,0,0,0.1) 0px 0px 6px 0px) and one featured "PickUp" button (rgba(0,0,0,0.17) 0px 1px 10px 0px). Depth and grouping come from flat tinted surfaces and thin hairlines (#e6e6e6, #d6d5d5). When emphasis is needed, the system reaches for color — corporate teal (#139cb7) or kintone yellow (#ffbf00) — never a heavy card stack. This keeps Japanese B2B software feeling clean, fast, and approachable rather than institutionally heavy.

7. Do's and Don'ts

Do

• Use corporate teal (#139cb7) as the single action color on Cybozu-corporate surfaces — keep it the link/CTA signal
• Use the Hiragino Kaku Gothic Pro stack for corporate surfaces and Roboto + Noto Sans JP for kintone
• Use kintone yellow (#ffbf00) for the product's brand chips, banners, and decorative accents
• Use warm ink (#333333 corporate, #231200 kintone) instead of pure black for reading text
• Separate sections with flat tints (#f6f6f6, #f3f3f3, #fff5e1) and #e6e6e6 / #d6d5d5 hairlines, not shadows
• Keep kintone cards flat with a 10px radius and a thin #d6d5d5 border
• Use positive letter-spacing on kintone headlines (+2.6px at 52px) for an approachable cadence
• Pair English section labels in muted grey (#aaaaaa) above Japanese content on corporate pages

Don't

• Mix the corporate teal and the kintone yellow on the same surface — they are two distinct brand identities
• Use heavy drop shadows for elevation — Cybozu is near-flat; reserve the soft rgba(0,0,0,0.1) shadow for circular icon buttons
• Use pure black (#000000) for body text — use #333333 (corporate) or #231200 (kintone)
• Use tight negative tracking on kintone headlines — kintone tracks positive for friendliness
• Set corporate nav links in a light weight — corporate nav is weight 700
• Spread teal across many corporate elements — it dilutes the single-action signal
• Use Hiragino on kintone or Roboto/Noto on the corporate site — the two stacks stay on their own surfaces

8. Responsive Behavior

Breakpoints

Touch Targets

• kintone primary CTA at 64px height — an unmistakable target
• kintone secondary outlined buttons at 66px height with generous left padding
• Corporate nav items within the 56px header; circular icon buttons at 40px

Collapsing Strategy

• Corporate: bilingual section bands maintain full-width treatment; news/products lists stack
• kintone: 52px headlines scale down on mobile, weight 700 and positive tracking maintained
• kintone feature-card grids collapse multi-column → 2-up → single stacked
• Tinted/white alternating sections keep full-width treatment

Image Behavior

• kintone product screenshots and illustrations carry no shadow at any size, consistent with the flat system
• Cards maintain 8–10px radius across breakpoints
• Corporate circular buttons keep their soft rgba(0,0,0,0.1) shadow

Iteration Guide

1. Pick the surface first: corporate (teal #139cb7 + Hiragino + #333333) vs kintone product (yellow #ffbf00 + Roboto/Noto + #231200) — never mix them
2. Teal is the single corporate action color; don't spread it
3. kintone headlines track positive (+2.6px), weight 700 — approachable, not tight
4. Near-flat: separate with #f6f6f6/#f3f3f3/#fff5e1 tints and #e6e6e6/#d6d5d5 hairlines
5. Reserve soft shadow (rgba(0,0,0,0.1) 0 0 6px) for corporate circular icon buttons only
6. Warm ink everywhere — #333333 (corporate) / #231200 (kintone), never #000000 for reading
7. kintone cards: 10px radius, 1px #d6d5d5 border, no shadow

10. Voice & Tone

Cybozu's voice is calm, civic, and teamwork-first — a Japanese B2B software maker that frames technology as a way to build "チームワークあふれる社会" (a society overflowing with teamwork) rather than as a competitive weapon. The corporate site reads like a thoughtful public-facing publication: bilingual section labels, measured news entries, no hype. kintone shifts register toward warm and democratizing — its tagline "みんな、つくれる。" ("Everyone can build.") and chips like "さわってみよう！" ("Give it a try!") invite the non-engineer to participate, decoding "no-code / low-code" into something friendly.

Voice samples (verbatim from live surfaces):

• "サイボウズ株式会社" — corporate page title (institutional register). (verified live 2026-06-17)
• "kintone（キントーン） | みんな、つくれる。業務アプリがつくれるサイボウズのノーコード・ローコードツール" — kintone page title (democratizing promise). (verified live 2026-06-17)
• "30日間無料お試し" / "個人情報不要！" — kintone trial CTAs (low-pressure, concrete). (verified live 2026-06-17)

Forbidden register: aggressive sales urgency, fear-based B2B FUD, undefined enterprise jargon, anything that makes "no-code" sound exclusive or intimidating.

11. Brand Narrative

Cybozu (サイボウズ) was founded in 1997 in Matsuyama, Ehime by Yoshihisa Aono and co-founders, and grew into one of Japan's most influential groupware companies — the maker of Cybozu Office, Garoon, and, since 2011, kintone. Its corporate mission, stated plainly across cybozu.co.jp, is to build "チームワークあふれる社会を創る" (to create a society overflowing with teamwork). That mission is unusually load-bearing: Cybozu is also well known in Japan for pioneering flexible work styles ("働き方改革"), and it frames its software not as productivity tooling but as social infrastructure for collaboration.

kintone is where Cybozu's design-led culture is most visible. The product reframes business-application building — historically the domain of engineers and consultants — as something "みんな、つくれる" (everyone can build). Around it sits an open product-design organization: the kintone Design System (Figma + the kintone-ui-component npm library + Storybook docs at ui-component.kintone.dev), and the long-running Cybozu Product Design Magazine on note.com/cybozu_design, where designers publish their process, organization changes, and research in the open.

What Cybozu's design refuses, visible on the surface: the heavy, intimidating chrome of legacy enterprise software (no shadow-stacked dashboards, no corporate navy-and-grey severity) and the hard-sell urgency of Western SaaS marketing. What it embraces: a calm civic corporate voice in teal (#139cb7), a warm and democratizing product voice in yellow (#ffbf00), bilingual accessibility, flat hairline-separated layouts, and a transparent, published design practice.

12. Principles

1. Teamwork is the product. Cybozu's stated mission is a society overflowing with teamwork; software is the means. UI implication: favor clarity and collaboration cues over feature density; the interface should never feel like a competition.
2. Everyone can build. kintone's "みんな、つくれる" democratizes app-building beyond engineers. UI implication: decode jargon into friendly tools; positive headline tracking and warm yellow make the product feel inviting, not technical.
3. Two voices, one philosophy. A civic corporate teal and a warm product yellow are kept distinct. UI implication: never mix the teal and yellow systems on one surface — each carries its own register.
4. Flat and human. Near-shadowless, hairline-separated layouts keep B2B software approachable. UI implication: separate with tint and hairlines; reserve shadow for the smallest interactive accents.
5. Design in the open. The kintone Design System and Product Design Magazine make the practice transparent. UI implication: components are documented, reusable, and consistent — the system is a shared, published artifact, not tribal knowledge.

13. Personas

Personas below are fictional archetypes informed by publicly observable Cybozu / kintone user segments (Japanese SMB operations staff, non-engineer "citizen developers", enterprise IT, and Cybozu's own product designers), not individual people.

田中美咲, 38, 松山. Operations lead at a regional manufacturer. Not an engineer, but builds her own 案件管理 (case-management) apps in kintone because "みんな、つくれる" turned out to be literally true. Values that the cards and forms feel friendly rather than technical.

佐藤健, 45, 東京. Corporate IT manager evaluating Garoon and kintone for a 300-person company. Reads cybozu.co.jp's calm, factual IR and news pages and trusts the civic, non-hype tone. Cares that the design feels stable and accessible, not flashy.

鈴木あみ, 29, 大阪. A product designer at Cybozu contributing to the kintone Design System and writing for the Product Design Magazine. Believes design should be published and shared; cares about the kintone-ui-component library staying consistent across the product.

14. States

15. Motion & Easing

Durations:

Easings:

Motion rules: Motion is functional and quiet — consistent with the calm, flat aesthetic. Corporate teal links and kintone buttons respond to press with a subtle color/opacity shift; cards fade-in from below at motion-standard / ease-enter. No bounce or spring — Japanese B2B teamwork software signals steadiness and trust, not playfulness. Under prefers-reduced-motion: reduce, all transitions collapse to instant; the product remains fully functional.
