[News Space=Reporter seungwon lee] Jeju Samdasoo maintained its undisputed No. 1 position by recording a 40.4% share of the domestic drinking water market in the first quarter of 2025.

Jeju Samdasoo has built a solid trust by staying with consumers for 27 years based on clean raw water collected from a single water source on Mt. Halla. The thorough quality management system, which has not had a single case of unsuitable water quality or administrative action since its launch, is considered a key factor in driving consumer trust.

Brand marketing was also effective. This year, the brand message of ‘Trustworthy Water’ was strengthened through a new advertising campaign, such as selecting actress Park Bo-young as a model and introducing Jeju Samdasoo’s CM song ‘Joha Masim Song’. In addition, brand touchpoints were expanded through consumer participation programs such as Instagram challenge events.

Various activities encompassing both online and offline led to an expansion of consumer response. Jeju Samdasoo's flagship store 'Cafe Samdakoji' operated an escape room concept pop-up store 'Honjeo Opseo, Samda Village!', expanding experiential content and broadening the brand experience to Generation Z.

Online, we have increased accessibility through digital channel strategies such as strengthening the operation of home delivery apps and official online malls and expanding regular delivery programs. In addition, we have created opportunities for communication with consumers by holding live broadcasts of brand planning exhibitions and tours of the Jeju Samdasoo factory to commemorate the 30th anniversary of our founding.

Jeju Development Corporation President Baek Gyeong-hun said, “Jeju Samdasoo has led the market based on thorough trust in the value and quality of clean water sources,” and “We will continue to establish ourselves as the most trustworthy bottled water brand through quality innovation and active communication that meets consumers’ expectations.”
