Install

pip install jpstat

estat API

estat is the official site for government statistics in Japan. Its api service offers data of over 250+ statistics in Japan. You need to register an api key to access to the statistics.

Functions

All functions return one or multiple pandas DataFrames.

To see a list of statistics offered by estat api

import jpstat
stat = jpstat.estat.get_stat(key=YOUR_API_KEY)

To search data by either the code of a statistic or some key words

data = jpstat.estat.get_list(statsCode="00400001")
data = jpstat.estat.get_list(searchWord="企業")

To download data

data, note = jpstat.estat.get_data(statsDataId="0000040001")

Configuration

You can pass the estat api key to each function. Or you can set a configuration

jpstat.options["estat.api_key"] = "MY_API_KEY"

You can also set the language from Japanese (default, "J") to English

jpstat.options["estat.lang"] = "E"

To see a list of valid configuration options

jpstat.config.describe_options()

estat File

Many statistics and datasets in estat can not be accessed through API, but are excel, csv, or pdf files and can be downloaded. Here jpstat provides the functions that scrapes the information of statistics and download the files. Api key for estat is not needed, and the result is in Japanese only.

Functions

To see a list of all statistics in estat that have downloadable files

data = jpstat.estatFile.get_stat()

It will take some time to scraping the website of estat at the first time and then save the list to options["estat.data_dir"]. From then on, the function would first try to read the local file. You can force to scrape again by setting update=True.

To search data files by code of a statistic and the survey year (optional)

data = jpstat.estatFile.get_list(statsCode="00400001")
data = jpstat.estatFile.get_list(statsCode="00400001", year="1950")

Again, you can save the result by setting save=True, and from next time jpstat would first check if the result already exists.

To download the file by using the information of data id and file type ("EXCEL"/"CSV"/"PDF") gotten from the result of estatFile.get_list

jpstat.estatFile.get_file(statsDataId="000029094935", file_type="EXCEL")

The file would be downloaded to current folder by default.
