It is impossible to conduct a comprehensive litigation records check in Japan.

Only the supreme court records are open to the public in Japan. The records date back over ten years.

FYI
You should consider the legal system of each country. Japan and most East Asian countries adopted Continental Law or the written law form mainly Germany. It is contrary to the Common Law or the case law that the US adopted. The written law means the description of the laws is written. So you don’t have to search precedent cases. That’s why litigation records are not open to the public, and they are mainly not searchable. In the case of Common Law, no attorneys can operate without getting access to the litigation records database because the laws are constantly changing depending on the previous cases.

Based on the announcement of The Ministry of Justice Japan in 2007, it is defined as follows: "Groups or individuals who pursue economic benefits using violence, power, and fraudulent methods.”

「暴力、威力と詐欺的手法を駆使して経済的利益を追求する集団または個人」

Anti-Social Forces include Japanese mafias (Yakuzas), of course. But they cover scammers, as well. Therefore, it is a bit ambiguous in the definition.
