densha: A Living Voxel Tokyo for Language Learners
"An ambient Japanese study room you just press play into."
Experience the magic of densha, an immersive environment where you can ride the Yamanote line through a meticulously crafted voxel version of Tokyo. This isn't just a game but a living simulation designed to help you study Japanese.
🌐 The Immersive Experience
The world of densha is dynamically linked to the actual conditions in Japan. The environment adapts based on:
| Feature | Synchronization Detail |
|---|---|
| Clock | Matches Japan's real-time hour and minute |
| Weather | Reflects current atmospheric conditions |
| Seasons | Changes visually to match the time of year |
🎧 Study Integration
While you glide through the city, the atmosphere is set by a lofi soundtrack. The learning process is seamless:
- Audio: N5-level Japanese sentences are read aloud.
- Visuals: These sentences drift across the screen as subtitles.
🛠️ Technical Flow
📋 Your Study Session
