Native Japanese Translator needed — Flight Tracker App (UI Review)

We are looking for a native Japanese speaker (日本語ネイティブ) to review and refine a Japanese translation for WaiAir — a real-time flight tracker app for Southeast Asia. About the app: WaiAir shows live flight status, gate info, delay alerts, baggage info, radar and a pickup assistant. Used by travelers and people picking up family or friends at the airport. The job: Japanese travelers expect precision. A machine translation is never enough — we want the app to feel like it was built by a Japanese team. That means natural phrasing, the right keigo level, and terminology that any frequent flyer in Japan would immediately recognize. - Review and refine the attached JSON translation file - Replace any unnatural or machine-translated phrasing - Use correct aviation terminology as used in Japan - Ensure consistent and appropriate politeness level (丁寧語) - Keep all placeholders exactly as-is, for example: n, name, iata, clock Deliverable: - Corrected .json file - Saved as UTF-8 encoding - Same key structure as original, only values changed Additionally, translate these 3 short sentences for our website. We want them to feel warm, trustworthy and natural — not translated: Tagline: Track flights in real-time across Southeast Asia Short description: Live flight status, gate info, delay alerts and radar — for travelers and people picking up at the airport. Extra line: Never miss a flight — WaiAir keeps you updated every step of the way. Requirements: - Native Japanese speaker living in Japan or with strong ties to Japanese culture - Experience with app localization or UI translation - Frequent flyer or aviation knowledge is a big plus Delivery within 3-5 days.
