About this app
Kizuna helps you decide, in seconds, whether today is a good day to visit a client, send a gift, or travel in Japan. Built for people who work, live, or travel between cultures - clear answers, no fluff, and no missed public holidays. WHAT KIZUNA DOES 1. Today view: one card that tells you if today is a national holiday, a long weekend, or a sensitive etiquette window - now with a weather-aware context for your day. 2. Full Japan holiday calendar with month-by-year browsing and long-weekend highlights. 3. Scenario advice for client visits, gift giving, return gifts, and business trips - each with the reason and better alternative dates. 4. Culture-aware etiquette cards written from a Japanese point of view, not machine-translated fluff. 5. Smart reminders before Golden Week, Obon, Oseibo, Ochugen, and other moments that shape the year.
