About this app

【Record your castle visits accurately and simply.】

ShiroLog is the ultimate companion for exploring over 1,000 castles across Japan. We focused on "ease of use in the field" rather than complex features, pursuing a minimalist design that removes all the clutter.

■ Our Commitment
* Minimalist Design: No complicated settings. Just select a castle and save your photos or notes. Build your own "Castle Encyclopedia."
* Extensive Database: Pre-set with over 1,000 castle names across Japan. Easily record accurate names without worrying about variations.

■ Diverse Missions to Guide Your Journey
Don't just record—let our curated missions guide your adventure from various angles:
* National: Conquer the "5 National Treasure Castles."
* Warlords: Follow the footsteps of legends like "Oda Nobunaga."
* Regional: Deep dive into areas like "Existing Castles of Shikoku."
New missions like "Castles in the Sky" are added regularly!

■ Developer's Story
Developed with my 8-year-old son, an avid castle fan, to create the "easiest app to use on-site." It is kid-tested and approved for its simple, intuitive operation. We combined a minimal user experience with our deep respect for Japanese history.

Take ShiroLog with you and step onto the next stage of history!
