Minimalist app icon with a white open book, golden circle with white kanji '言' (words), and stars on a navy blue background.

Design a modern, minimalist mobile app icon for a Japanese learning app called "Kotoba Academy." The icon should have a deep navy blue (#0F3D91) rounded-square background with smooth, rounded corners and a subtle matte finish. Centered in the icon is a stylized open book drawn with clean, thick white lines. Rising from the center crease of the book is the white kanji 「言」 (meaning "words" or "speech"), perfectly centered and using a bold, geometric Japanese font. Behind the kanji is a soft golden-yellow (#FFD54A) circular glow, about 60% of the icon's width, creating contrast without overpowering the design. Add two or three tiny golden sparkle stars around the upper portion of the kanji to symbolize learning and achievement. Keep the design perfectly symmetrical with generous negative space. Avoid gradients, shadows, 3D effects, textures, flags, anime elements, cherry blossoms, torii gates, or unnecessary decorations. The style should be flat, premium, professional, highly recognizable at small sizes, and suitable for both iOS and Android app stores. The icon should communicate education, Japanese language, and mastery in a clean and timeless way. Use only four colors: deep navy blue, white, golden yellow, and a very light blue accent (#6EC6FF) for a thin highlight along the top edge of the book. The overall appearance should feel modern, trustworthy, elegant, and memorable, similar to the simplicity of Duolingo or Notion's branding while remaining completely original. Mehr sehen
