Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
audit_japan_uxAudit Japan UXread-onlyComprehensive Japanese UX audit covering 7 categories: layout (density, breadcrumbs, CTA placement), typography (fonts, line-height, kinsoku shori), visual (color meanings, red-name taboo, dark theme), navigation (phone number, footer links, hamburger rules), trust (会社概要, case studies, proof numbers, legal links), content (Japanese text, FAQ, pricing tables), and mobile (viewport, tel: links, touch targets). Returns letter grade (A-F), category scores, and prioritized fixes.
check_jp_typographyCheck JP Typographyread-onlyAudit CSS and markup for Japanese typography issues. Checks: font stacks (Noto Sans JP, Hiragino, Yu Gothic), line-height (1.7-2.0 for Japanese body text), font sizes (14px body minimum, 12px captions floor), kinsoku shori (line-break: strict), text-on-photo overlays, font-feature-settings 'palt' on headings, font-synthesis, and more. Returns score, issues, and a recommended font stack for your context.
design_direction_for_japanDesign Direction for Japanread-onlyGenerate a Japan-specific visual direction for a website or interface. Takes a loose brand type, audience, and industry, then returns a practical design brief covering visual direction, information density, color palette, typography, imagery style, CTA style, trust layout, and section priorities.
generate_jp_formGenerate JP Formread-onlyGenerate culturally correct Japanese form markup with proper field order (姓→名), furigana, 3-field phone, 〒 postal address, 年月日 dates, and context-appropriate keigo. Use this when building any form for a Japanese audience.
generate_jp_placeholderGenerate JP Placeholder Dataread-onlyGenerate realistic Japanese test data for prototypes and development. Returns names (kanji + katakana furigana + romaji), addresses (real postal codes and prefectures), phone numbers (correct 3-field format), company names, and dates (both Gregorian and Japanese era format like 平成4年3月15日).
get_seasonal_contextGet Seasonal Contextread-onlyGet the current Japanese seasonal context for design decisions. Returns: current season with traditional colors, active events (正月, 花見, お盆, etc.), upcoming events, the current microseason (二十四節気), recommended design colors, and warnings (e.g., do not launch during Golden Week). Covers all 24 Japanese microseasons and 24+ major events.
review_jp_uiReview JP UIread-onlyReview CSS/markup against the Japanese UI standard (typography, colour, font performance) and return a pass/needs_work/fail verdict with violations, JLReq/JIS citations, and fixes. The front-end correctness enforcer — run on any UI (including Western-built) before shipping to Japan; call transform_for_japan to auto-apply form/copy fixes.
score_japan_readinessScore Japan Readinessread-onlyScore any page or component for Japan-readiness on a 0-100 scale. Analyzes 5 categories: forms (name order, furigana, phone, postal), copy (keigo, Japanese text, placeholders), trust (特定商取引法, phone number, company info), typography (font, size, line-height), and cultural (seasonal awareness, imagery). Returns breakdown with issues and quick wins per category.
suggest_keigo_levelSuggest Keigo Levelread-onlySuggest appropriately polite Japanese UI text based on context. Maps business context to keigo level (casual → very_formal) and returns the right Japanese translation for buttons, error messages, empty states, confirmations, and more. Includes alternatives for different formality levels.
transform_for_japanTransform for Japanread-onlyTransform Western markup into Japan-ready markup. Automatically fixes: name field order (firstName/lastName → 姓/名), adds furigana, splits phone into 3 fields, restructures address to 〒 postal format, translates buttons with appropriate keigo, replaces Western placeholder data with Japanese examples. Shows before/after scores and explains every change.
validate_jp_formValidate JP Formread-onlyAudit an existing form against Japanese UX conventions. Checks for: name field order (姓/名), furigana, 3-field phone, postal code auto-fill, keigo-appropriate button text, full-width character handling. Returns score (0-100), issues with fixes, and what passed.
