Japan e-Stat MCP. Get raw economic and census data directly from the source.
Gemini Works with every AI agent you already use
…and any MCP-compatible client
Just plug in your AI agents and start using Vinkius.
Japan e-Stat MCP Server queries the official Japanese Portal of Government Statistics. Your AI client finds and pulls raw economic and demographic data—including population, GDP, trade, and CPI—from the e-Stat national database.
Use `search_japan_statistics` to find table IDs by keyword (e.g., 'GDP', 'Tokyo population'). Then, pass the ID to `get_japan_stats_data` to pull specific, raw numbers across any time period or region.
It’s the fastest way to get reliable, government-sourced data for macro analysis.

What you can do with this MCP connector
Japan e-Stat MCP Server lets your AI client query the official Japanese Portal of Government Statistics. You're pulling raw economic and demographic data—think population, GDP, trade, and CPI—straight from the e-Stat national database. It's the fastest way to nail reliable, government-sourced numbers for macro analysis. search_japan_statistics finds the right table IDs by keyword; you just feed it terms like 'GDP' or 'Tokyo population'.
After you get the ID, you pass it to get_japan_stats_data to pull specific, raw numbers across any time period or region. You can restrict the data you pull to a specific region like 'Tokyo' or a time frame like '2022 Q3'. The API even supports English translations for table names and categories when they're available, so you don't get stuck on Japanese characters. search_japan_statistics returns a list of relevant table IDs, titles, and the organization that published the data. get_japan_stats_data pulls raw numbers, classifying the output by the time period, the area, and the value.
You'll get the data you need without having to wade through confusing PDFs. get_japan_stats_data lets you define the category, the geographic area, and the time period for the specific data point you want. You're working with data from the world's third-largest economy, and it's all right here. search_japan_statistics searches the e-Stat database using keywords, giving you the table IDs you need. get_japan_stats_data pulls the numbers, letting you specify the time span and the area.
You can keep your workflow moving fast and get the hard data you're looking for.
How Japan e-Stat MCP Works
- 1 First, ask your agent to run
search_japan_statisticsusing a general topic keyword (e.g., 'population' or 'trade'). - 2 Next, take a specific Table ID from the search results. This ID is required to proceed.
- 3 Finally, run
get_japan_stats_data, supplying the required Table ID, the specific category, the geographic area, and the time period.
The bottom line is: search for the table ID first, then use the ID to pull the actual data.
Who Is Japan e-Stat MCP For?
The global macro analyst who needs reliable, verifiable data sources. It's for the researcher who can't afford to spend days clicking through government websites. It’s for anyone who needs to compare Japan's economic performance against other global metrics, fast.
Runs comparisons of Japanese GDP components or labor force data across different quarters.
Gathers recent trade data, industrial production indices, and foreign market statistics.
Pulls specific census data (population by prefecture) or historical CPI trends for papers.
What Changes When You Connect
- Reliable Data: You pull official numbers from the Japanese government's e-Stat portal. This isn't scraped data; it's the primary source.
- Targeted Retrieval: Use
search_japan_statisticsto narrow down thousands of tables. You don't waste time browsing multiple ministry websites. - Full Scope Coverage: The server covers core economic areas: population, GDP, industrial production, foreign trade, and labor force statistics.
- Structured Output:
get_japan_stats_datadelivers raw, structured numbers, classified by category, area, and time. No more messy CSV downloads. - Global Macro Ready: Whether you're checking CPI trends for Tokyo or overall national accounts, the data structure supports global comparison.
- Language Support: The API supports English-translated table names and categories (
lang=E), which helps when you don't speak Japanese.
Real-World Use Cases
Comparing Regional Population Shifts
A researcher needs to compare Tokyo's population to Osaka's over the last decade. They run search_japan_statistics with 'population'. They find the correct census table ID, then use get_japan_stats_data to pull the specific numbers for both prefectures and the desired years.
Tracking Automotive Industry Decline
An auto parts analyst needs the Industrial Production Index (IIP) for the motor vehicle sector. They run search_japan_statistics for 'industrial production'. They locate the METI table ID and use get_japan_stats_data to pull the specific index values, noting the month-over-month change.
Analyzing Trade Balance Changes
A trade economist needs to see how Japan's imports and exports changed in Q2 2023. They run search_japan_statistics for 'foreign trade'. They find the relevant table ID and use get_japan_stats_data to pull the raw import/export values for that specific quarter.
Calculating CPI Year-over-Year Growth
A finance analyst needs the latest CPI data for Tokyo. They run search_japan_statistics for 'consumer price index'. They grab the correct table ID and use get_japan_stats_data to pull the all-items index, instantly showing the year-over-year growth percentage.
The Tradeoffs
Searching for data without IDs
Asking the agent, 'Give me Japan's GDP for 2023.' The agent fails because the raw data tool needs a specific table ID to run.
→
First, run search_japan_statistics with 'GDP' to get the required table ID. Then, pass that ID to get_japan_stats_data and specify the year 2023.
Using the wrong tool for the job
Trying to get a list of available data types by running get_japan_stats_data first. This tool requires the ID you don't have yet.
→
Always start by running search_japan_statistics with a general keyword. This gives you the list of IDs you need to work with.
Assuming data availability
Asking for data from a niche sector that the government hasn't published yet. The agent will fail and give a generic error.
→
Check the search results from search_japan_statistics to confirm the data type or sector exists and is published by the Ministry of Economy, Trade and Industry (METI).
When It Fits, When It Doesn't
Use this if your research requires verifiable, official statistics from the Japanese government. You need specific numbers—like GDP figures, CPI indices, or population counts—that you can trace back to the e-Stat portal.
Don't use it if you need anecdotal data, market sentiment, or non-public corporate records. If you're just looking for a general overview of Japanese economic trends, start with a high-level search engine. If you need to pull a specific time series (e.g., 'Tokyo population 2010-2020'), this is the right tool.
If you are already in a highly specialized domain (like advanced semiconductor supply chain modeling), you might need a proprietary API, but for general macro and demographic analysis, this server is the standard.

Available Capabilities
Gathering Japanese economic data used to take hours of clicking through government websites.
Before this server, pulling a dataset was a manual process. You'd open the Ministry of Internal Affairs and Communications site, navigate to the 'Population' section, find the right year, download the CSV, then repeat that process for trade data on the Ministry of Economy, Trade and Industry site. It was a nightmare of tabs, logins, and copy-pasting data points into a single spreadsheet.
With the Japan e-Stat MCP Server, you tell your agent what you need—say, 'Tokyo population by prefecture.' The agent runs `search_japan_statistics`, gets the table ID, and then uses `get_japan_stats_data` to pull the full, structured data set. You get the numbers, organized and ready for analysis, in one go.
Japan e-Stat MCP Server: Retrieve specific statistical data.
You never have to navigate the complex structure of the e-Stat site again. No more guessing which ministry holds the data. The server handles the cross-referencing of official government tables.
It just works. You tell it the topic, and it gives you the precise, structured data, bypassing every confusing menu and download button.
