Most Japan prep tools are either full language courses or phrasebooks that fall apart the moment you're actually there. Pooki requires zero Japanese knowledge. In less than 1 hour you'll know the essentials: exit signs, konbini survival, how to order food, temple etiquette. No grammar. No hiragana. No prior study. Cards split into what you'll see on signs and what you'll say out loud. Mobile-friendly. Free to play in the browser.
