Usage

Fetch notices for a specific year.

Fetching notices for the year specified in the parameter. This parameter may be available after 2008.

import sagikoza
accounts = sagikoza.fetch('2025')
print(accounts[:5])
# [{'uid': 'd06beb...', 'bank_name': 'みずほ銀行', 'name': 'グエン テイ ホアイ ニエン', 'name_alias': 'NGUYEN THI HOAI NHIEN' ...}, ...] 

Fetch notices for the last 3 months

Fetching without arguments to get notices from the latest 3 months.

import sagikoza
accounts = sagikoza.fetch()
print(accounts)
# [{'uid': 'd06beb...', 'bank_name': 'みずほ銀行', 'name': 'グエン テイ ホアイ ニエン', 'name_alias': 'NGUYEN THI HOAI NHIEN' ...}, ...] 

Fetch raw data

If you want to fetch raw data before normalization, set the normalize parameter to False to skip the normalization process.

import sagikoza
accounts = sagikoza.fetch('near3', normalize=False)
print(accounts)
# [{'uid': 'd06beb...', 'bank_name': 'みずほ銀行', 'name': 'ＮＧＵＹＥＮ　ＴＨＩ　ＨＯＡＩ　ＮＨＩＥＮ　（グエン　テイ　ホアイ　ニエン）', ...}, ...] 

Save data example

I recommend you to use pandas's to_parquet, if you would like to save the data in local.

import pandas as pd
import sagikoza
accounts = sagikoza.fetch()
df = pd.DataFrame(accounts)
df.to_parquet('accounts.parquet', index=False)

Function Specification

• fetch(year: str = "near3") -> list[dict]
  • Specify a year (YYYY) or "near3" for the latest 3 months
  • Raises an exception on failure

Internal Workflow

1. Fetch notice list (POST: sel_pubs.php)
2. Fetch submits by Financial Institutions (POST: pubs_dispatcher.php)
3. Fetch subjects (GET: pubs_basic_frame.php)
4. Fetch accounts of financial crime (POST: k_pubstype_01_detail.php, etc.)

Parameters required for each step are extracted from the HTML and used for subsequent page transitions.

Logging

Uses Python's standard logging module. For detailed logs:

import logging
logging.basicConfig(level=logging.INFO, format='%(asctime)s %(levelname)s %(name)s %(message)s')
import sagikoza
sagikoza.fetch()

By default, only WARNING and above are shown. For more detail, set level=logging.DEBUG.
