Industry & Occupation
Classification
Summary
The soaking softening worker is a technician responsible for the pre-treatment process in leather manufacturing, soaking raw hides in water to soften them and adjusting to a suitable state for subsequent tanning and finishing processes.
Description
The soaking softening worker specializes in the initial pre-treatment stage of the leather manufacturing process. Raw hides, salted and stored, are immersed in dedicated water tanks to wash away salt and dirt, while using chemicals (degreasing agents, enzyme agents, etc.) to swell and soften the fibers. Thorough management of immersion time, water temperature, and pH is required to maintain uniform softening. After processing, water is drained and dried to achieve appropriate humidity and flexibility, then handed over to tanners and finishers. The work environment is humid and physically demanding, making knowledge of safety, hygiene management, and chemical handling essential.
Future Outlook
While Japan's leather manufacturing industry is trending toward downsizing, interest in high-value-added leather products and traditional techniques remains strong. Amid advancing automation and mechanization, the succession of skilled artisans' techniques is a challenge.
