    Preview resource

    Take resource URLs from get_dataset. Best for CSV/JSON; binary formats return limited bytes. Great for inspecting actual rows before deeper analysis. Preview the raw content of a dataset resource (CSV/XLSX/JSON first rows)

Building your own app? The connector is yours to use.

You don't need a client to put Tokyo Open Data Portal to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 5 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Tokyo Open Data Portal, so you can see the experience inside your AI.

It does not authenticate your account with Tokyo Open Data Portal. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Tokyo Open Data Portal owners ask.

  • 01

    Do I need an API key or registration?

    No. The portal is a standard CKAN catalog with a fully public API. search, metadata, categories and organizations all work without authentication.

  • 02

    Why must search terms be in Japanese?

    Dataset titles are published in Japanese; the Solr index matches title: term queries, and English terms like "tourism" match nothing. Use Japanese keywords (観光, 防災, 人口) or browse by category/organization instead. The list_categories capability includes the English meaning of each category.
