Japanese Translation of Bestseller 'The Word Vessel' Released

Discover 21 Co., Ltd. released the Japanese translation of 'The Word Vessel' (by Kim Yoon-na, translated by Junko Yanada) on May 24, 2026 (with online pre-sales starting May 22).

This book, which sold over 500,000 copies and was a bestseller for 100 consecutive weeks in South Korean bookstores, has finally been translated into Japanese. It offers lessons on nurturing one's 'vessel' for anyone feeling drained by interpersonal relationships.

Nurturing the 'vessel' changes words and relationships

The author states, 'Each person has a vessel for words, and the size of that vessel determines the level of communication and the depth of relationships.'

People with 'small word vessels' lack the space to contain words, produce unnecessary speech, and cannot accept others' words. Conversely, people with 'large word vessels' can contain many words, select necessary ones, and deeply understand what others say.

Words are mirrors that reflect the speaker. To choose appropriate words and listen deeply to others, one must first understand their own emotions and thought patterns, and nurture a larger inner 'vessel'.

A practical guide from a South Korean specialist

The author, Kim Yoon-na, is the director of the Institute of Words and Hearts, where she provides coaching and lectures for major South Korean companies. She systematically explains everything from methods for self-reflection, 'listening skills' that don't exhaust you, to 'speaking (questioning) skills' that unlock the heart. This is a practical guide for achieving non-exhaustive communication by tuning one's inner state rather than just learning superficial skills.

<Feedback from South Korean readers> 'I realized I shouldn't speak without thinking.' 'I want those who value inner warmth to read this.' 'Repeatedly reading this makes me feel like a different person.'

'Words' grow along with the heart. When your vessel is full, warm and gentle flowers of words will begin to bloom between you and your loved ones.

Recommended for:

- Those who often regret saying unnecessary things. - Those unable to forget past words that deeply hurt them. - Those who feel anxious in communication because they cannot articulate their thoughts well. - Those who feel mentally drained due to relationship issues stemming from communication.
