The nature of the scores
QQS / RQS / AHS and other scores are not metrics for deciding whether a council is "good" or "bad". They are quantitative descriptions of structural features of council deliberation (such as the concreteness of questions or the directness of answers). They must not be used to criticize or attack specific municipalities or members.

robots.txt. - Request intervals are at least 1 second to avoid overloading servers.
- Collection is limited to public documents (such as council minutes).
5. Prohibited uses
The following uses of the data are prohibited.
- Harassment and defamation — using the data to defame, harass, or attack specific individuals (lawmakers, staff, etc.).
- Unauthorized election campaigning — unauthorized use in election campaigning that supports or opposes a specific candidate.
- Fabrication — manipulating or selectively quoting the data to create content that gives a factually incorrect impression.
6. Governing law and dispute resolution
The interpretation and application of these Terms of Use are governed by the laws of Japan.
Any dispute arising between the operator and a user in relation to these Terms or to the use of KOUSOU 0 shall be subject to the exclusive jurisdiction of the Tokyo Summary Court or the Tokyo District Court in the first instance, depending on the amount in dispute.
However, if the user qualifies as a “consumer” under Japan's Consumer Contract Act, their rights under that Act are not waived. The consumer's right to choose jurisdiction and other rights under the Consumer Contract Act are not restricted by these Terms.
