About this app

AND Roppo is a smart legal code app that provides access to the latest legal information at all times, utilizing the e-Gov Law Search (https://laws.e-gov.go.jp) operated by the Digital Agency. English versions of laws can also be viewed using the Japanese Law Translation Database System (https://www.japaneselawtranslation.go.jp/ja/).

Furthermore, it allows you to view precedents related to the searched articles through its own case law database, and you can also search for related precedents using the Courts' Case Law Search (https://www.courts.go.jp/hanrei/search1/index.html).

It's ideal for legal professionals, law students, and bar exam candidates—anyone who wants to perform daily legal searches more intuitively and efficiently.

A major feature is the ability to instantly jump to a specific article by simply entering the article number, whether in practice or study. You can also view the main article AND referenced articles simultaneously, making it a legal code app that meets the needs of those involved in the legal field.

🌟 Main Features
🔢 Standard Article Number Search Keyboard
Quickly search for the desired article number using the dedicated numeric keyboard located at the bottom of the screen.
It specializes in meeting the common practical and educational need of "finding Article ○".
⚖️ Display of Related Case Laws
Like a case law compilation, you can view summaries of cases related to the searched article. For some cases, you can also jump to the original judgment text on the court's case law search site (https://www.courts.go.jp/hanrei/search1/index.html).
🪟 Simultaneous Viewing of Referenced Articles in a Sub-Window
Tapping a link within an article opens a sub-window displaying the referenced law. You can check the referenced article while viewing the original article, making research and learning smoother.
