All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-mode screenshot remains the same white/orange fixed palette, and the computed root colorScheme is normal. F01 high: The site does not honor the user’s dark color preference. |
respect-user-preferencesrespects-reduced-motion | pass | medium | Reduced-motion emulation matched reduce and getAnimations() returned none. |
respect-user-preferencesrespects-contrast | pass | medium | Forced-colors capture retains visible text, controls, borders, and focus affordances. |
implement-natural-interactionsview-transitions | issues | high | The page probe found no view-transition rules, and representative navigation is conventional full-document switching without continuity. F05 medium: State and route changes use abrupt legacy navigation. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No applicable feature or task was present in the representative scope. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No applicable feature or task was present in the representative scope. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | Home and travel screenshots show long, dense pages with static chrome; probes found no container or transition treatment to reflect scroll state or guide in-page jumps. F06 medium: Long pages provide little responsive navigation guidance. |
provide-guided-navigationanchored-positioning | issues | high | Home and travel screenshots show long, dense pages with static chrome; probes found no container or transition treatment to reflect scroll state or guide in-page jumps. F06 medium: Long pages provide little responsive navigation guidance. |

maximize-content-reduce-noiseno-intrusive-interruptions | pass | medium | All sampled initial-load screenshots exposed page content without a blocking modal or consent wall. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The homepage mobile capture is dominated by tiny banners, side rails, coupons, and repeated campaign tiles around the search form. F07 high: Promotional chrome and advertisements overwhelm the core booking task. |
maximize-content-reduce-noisereduced-chrome | issues | high | The homepage mobile capture is dominated by tiny banners, side rails, coupons, and repeated campaign tiles around the search form. F07 high: Promotional chrome and advertisements overwhelm the core booking task. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At a 360px viewport the homepage uses an effective 1146px layout; Hokkaido, travel, login, and results are visibly miniaturized. Only the activity template is meaningfully responsive. F02 critical: Core accommodation, destination, editorial, login, and result templates render as scaled desktop canvases on mobile. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The page probe found zero container rules, while the same global chrome and card/search modules are reused inside fixed-width shells. F03 medium: Shared components are not container responsive. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The focus probe measured many primary links at 11 to 30px high, and Lighthouse target-size failed. F04 high: Many controls are too small for touch even though keyboard outlines remain visible. |

support-core-task-successprimary-flow-completion | issues | high | At a 360px viewport the homepage uses an effective 1146px layout; Hokkaido, travel, login, and results are visibly miniaturized. Only the activity template is meaningfully responsive. F02 critical: Core accommodation, destination, editorial, login, and result templates render as scaled desktop canvases on mobile. |
support-core-task-successclear-system-state-and-recovery | pass | medium | The tested 404 states that the page does not exist and provides Japanese and English links back to the homepage. |

be-discoverablecrawlable-and-mobile-friendly | issues | high | Lighthouse failed crawlable-anchors on javascript:void links, while several public templates are fixed-width on mobile. F17 medium: Some links are JavaScript actions rather than crawlable navigation and mobile friendliness is inconsistent. |
be-discoverablecanonical-and-indexing-signals | pass | medium | Sampled public pages return 200, expose canonical URLs, and robots.txt lists multiple scoped sitemaps without blocking the sampled routes. |
be-discoverablestructured-and-shareable-metadata | issues | high | The homepage has Open Graph metadata but zero JSON-LD blocks; the activity page also has zero, despite organization, destination, and product-like content. F18 medium: Entity metadata coverage is inconsistent. |

be-resilientresilient-runtime-behaviour | pass | medium | Sampled menus/forms and pages rendered without clipped overlay failure or blank runtime shells. |
be-resilientoffline-and-installable | issues | high | Representative probes found no manifest URL and no controlling service worker; the site is a repeat-use commerce service with extensive search forms. F23 medium: The booking experience has no install or offline fallback surface. |

be-trustworthyhumane-error-handling | pass | medium | The empty search state and 404 explain the problem and direct the user to change conditions or return home. |
be-trustworthytrustworthy-input-assistance | issues | high | Both email and password inputs use autocomplete=off and have no labels, despite being standard sign-in fields. F25 high: The login form obstructs browser autofill. |
be-trustworthysafe-commercial-and-account-flows | issues | high | The login probe found no WebAuthn/passkey code; username and password both set autocomplete=off and lack associated labels. F21 high: Authentication is password-only and disables browser credential assistance. |
be-sustainableoptimised-assets | issues | high | The page transfers 5.84MB; image audit found 82 legacy images, 38 without responsive sources, and 30 below-fold images loaded eagerly. F26 high: Asset delivery is wasteful for the primarily transactional page. |
be-sustainableno-wasteful-work | issues | high | Third parties account for 4.56MB of 5.84MB and 276 of 481 requests, dominated by analytics and advertising scripts. F27 high: Third-party scripts consume most transferred bytes before user intent. |

be-memory-efficientbounded-footprint | issues | high | The baseline heap snapshot reported 1,052,755 heap nodes and 61.36MB self size; Performance memory reported 69.8MB used JS heap for a landing/search page. F29 medium: The activity landing page has a large baseline memory footprint. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Across the repeated-scroll comparison total heap nodes fell and edges changed by only about 0.14%, with no unbounded population signal. |
