ON:TANG — A well-being brand by Bondiq

A Moment to Return to Yourself.

Inspired by Jangsutang, a historic bathhouse in Ulsan, ON:TANG is a mental well-being brand centered on everyday self-care rituals. Through sensory experiences, moments of rest, and meaningful human connection, we invite people to slow down and reconnect with themselves.

Bangeojin and Jangsutang

A Place Where a Fishing Village Came to Wash Away the Day.

Located on the eastern coast of Ulsan, Bangeojin is a historic fishing village.

For generations, local bathhouses offered fishermen, women divers, and harbor workers a place to wash away the day's fatigue, rest, and connect with their neighbors.

Established in 1915, Jangsutang has been part of the community for more than a century. ON:TANG draws inspiration from the bathhouse's enduring spirit of rest, care, and human connection.

  1. c. 1897

    After the first Japanese fishing boats arrived, migration grew from 1908 and Bangeojin became a major port on the east coast.

  2. 1915

    Under Japanese rule, a fishing company built a bathhouse for its workers — the beginning of Jangsutang. Bangeojin had nine bathhouses at the time.

  3. After 1945

    After liberation, Korean owners took it over and it became the town's bathhouse. Even before there were buses, people came from Nammok, Jeonha and Ilsan.

  4. 1963

    Registered under the name Jangsutang — recorded as Ulsan's first public bathhouse.

  5. 1992

    Rebuilt as the red-brick building that stands today.

  6. Today

    More than a hundred years after it opened, it is still the neighbors' bathhouse.

Origin

Inspired by the Ritual of Bathing

The simple act of bathing offers a moment to pause, care for the body, and reconnect with the senses.

Inspired by this everyday ritual, ON:TANG brings the spirit of the bathhouse into modern self-care, creating space to slow down and turn our attention inward.
