Tokyo, the birthplace of iA, has always been a quiet engine behind our work. Its trains, in particular, offer something rare: calm, clarity, and momentum. Sitting on a Tokyo train, you don’t need to do anything—you just move forward. It’s the perfect mindset for writing.
That’s why we created Tokyo Focus Tracks—a series of ambient soundscapes inspired by train lines across the city. Designed to help you focus, they create a sonic space that clears your mind and keeps your fingers moving.
1. Keihin Tohoku Line
The Keihin–Tōhoku Line stretches from Ōmiya in Saitama Prefecture through central Tokyo down to Ōfuna in Kanagawa Prefecture, connecting major cities like Saitama, Tokyo, Kawasaki, and Yokohama. With 36 stations, it’s one of Tokyo’s busiest commuter lines, serving nearly 3 million passengers daily. The line’s name is derived from the characters for Tokyo (東京), Yokohama (横浜), and the Tōhoku Main Line (東北本線)
2. Yamanote Line
The Yamanote Line is Tokyo’s iconic loop line, encircling the city’s central districts and connecting major hubs like Shinjuku, Shibuya, Ikebukuro, and Tokyo Station. With 30 stations over 34.5 km, a complete loop takes about an hour.
3. Narita Sky Access
The Narita Sky Access Line connects Narita International Airport to central Tokyo, offering a swift journey into the heart of the city. Traversing both urban and suburban landscapes, it symbolizes transitions and new beginnings.
Each Tokyo Focus Track is designed to fade into the background, allowing your thoughts to take center stage. Use them when you need to concentrate, when the page won’t come alive, or when you seek a steady rhythm to guide your writing.
Why trains and type?
While these tracks are primarily soundscapes, we’ve also ensured they are visually attractive. We zoom into type, highlighting the intricate details of typography. There’s a secret affection among type designers and typographers for trains, and we wanted to celebrate that in our visuals.
We’re just getting started. More journeys through Tokyo’s soundscape are on the way. For now, plug in, press play, and let the city help you find your flow. Subscribe to our channel to stay updated on our latest releases and continue exploring Tokyo’s auditory landscapes with us.
