Where to start with Queria — usage and connection guides
Queria is a service that publishes data as a database, not as files or an API. You can work with Japanese open data straight from the browser, Python, a BI tool or an AI agent using SQL — no download, no conversion.
Try it first
No installation needed — run your first query:
uvx queria list
uvx queria sql "SELECT * FROM zipcode.main.mart_zipcode LIMIT 10"To try it in the browser, just open a table from the dataset list and you get a SQL editor and a data preview.
