Show HN: Yamanote.fun – A complete soundscape for Tokyo's Yamanote line After visiting Japan for the first time a decade ago I became completely enamoured with Tokyo's Yamanote Line railway loop. Particularly the sonic experience of it. Like so many others I fell in love with the charming departure melodies and enjoyed discovering experiences like Yamanot.es ( https://ift.tt/ANsRZ7W ) here on Hacker News when I returned home. But it wasn't until my second trip to Tokyo that I truly appreciated how much the door chimes, on-board announcements and train noise were contributing to the rich soundscape that I loved. I returned home and found myself playing YouTube videos of Yamanote Line journeys as I worked. The combination of sonics, ambience and softly spoken Japanese was incredibly soothing to me. But these recordings were often incomplete, poorly captured or out of date, and I wanted something far more comprehensive. So I gathered up all of the constituent parts from Reddit threads, YouTube videos and Japanese fan sites, and set about recreating the experience of riding the Yamanote Line in Logic Pro X. Melody, door chimes and announcement, all stitched together under a bed of train noise and ambience. I turned those soundscapes into an Alexa Skill ( https://ift.tt/qNyLt1j... ) in 2019 and began to think about a companion website to share the soundscapes with a wider audience. Seven years later and that website is Yamanote.fun: https://www.yamanote.fun/ . It's a small installable web app that plays the soundscapes like a playlist. All 30 stations and in both directions, since the inner and outer loops use different melodies. You can skip forward or back a station, and there's a scrub bar broken into melody / chime / ambience / announcement so you can jump straight to the bit you want. Each station has its own shareable link (yamanote.fun/jy13-ikebukuro-inner) that unfurls with the right station name and artwork when you share it. It's a progressive web app too, so you can add it to your home screen and it behaves like a native app. There's an option to offline the audio too. Under the hood it's relatively basic stuff: plain HTML, CSS & JS, audio served from Cloudflare R2 and the site hosted on Netlify. I was impressed to see how far I could get with the free tiers of these services. I designed the whole thing in Figma (I'm a Product Designer) and used Claude Code to architect and deliver the polished UI, PWA plumbing, offline caching and share-link infrastructure. I would love feedback, particularly from anyone who's ridden the real thing. https://www.yamanote.fun/ July 7, 2026 at 01:47PM
