Just gimme the data

Sure. data/raw-data.json.

Generating the data

First clone the project:

git clone https://github.com/adieuadieu/japan-train-data.git

Set up your environment with Google Cloud keys. To generate the data you need API access to Google's Translation and Geocoding APIs.

echo GCP_PROJECT=your-gcp-project-id-here >> .env
GCP_API_KEY=your-google-maps-api-key-here >> .env
GCP_KEYFILE=./gcp-keyfile.json >> .env

Then to start generating data:

yarn generate

Known Issues

1. Some of the translations are clearly crap.
2. In many cases, transliteration would be better than translation, but there's no API? Suggestions?
