Mastering Polite Language: New E-Book Releases

On August 8, 2025, Gakken, a subsidiary of Gakken Holdings Co., Ltd., is set to release two innovative e-books models: "The Simple Adult's Keigo (Polite Language) Conversion Dictionary" and "The Adult's Dictionary for Proper Language Usage." These electronic resources aim to help individuals navigate the complexities of using polite language in daily interactions.

Language plays a critical role in relationships, and many people often find themselves pondering whether they're using the correct expressions in various situations. Both e-books are designed to serve as reliable companions for those who seek to enhance their communication skills and confidence in using respectful language.

The Simple Adult's Keigo Conversion Dictionary

This dictionary offers a straightforward way to convert everyday phrases into polite language. Polite language (keigo) is essential in Japanese culture as it expresses respect and fosters smooth communication. This resource organizes 1,200 commonly used terms alphabetically, allowing readers to quickly find suitable keigo equivalents.

With clear labels, this book demystifies the often confounding differences between "sonkeigo" (respectful language) and "kenjougo" (humble language), ensuring users no longer struggle to apply these distinctions appropriately.

Additionally, readers will benefit from example sentences that showcase correct usage in realistic contexts. The inclusion of frequently confused terms helps prevent common verbal missteps, promoting more effective communication.

The Adult's Dictionary for Proper Language Usage

Complementing the first, this dictionary addresses potential linguistic pitfalls by highlighting points where people often stumble. It compiles a collection of 1,200 words that may be commonly misused or misunderstood in contemporary language. For instance, it explores how the meaning of phrases can shift over time, using the example of the term “君子は豹変す” (junzi wa hyouhensu), which originally referred to a noble person’s ability to recognize their mistakes and amend their ways. In modern times, however, it is increasingly perceived negatively—indicating a sudden change in attitude or opinion.

By classifying words according to their usage, pronunciation, and writing options—as well as distinguishing between similar-sounding kanji—this dictionary empowers users to choose precise phrasing that minimizes misunderstandings. Detailed explanations of collocations (words that typically pair with each other), idioms, and expressions prone to misuse are provided, easing concerns about word selection.
