4. Japan vs. China Sauna Suit Manufacturers: What’s Best for Your Brand?

Sourcing sauna suits for your gymwear brand often comes down to a critical decision: choosing between Japanese and Chinese manufacturers. Both countries offer world-class manufacturing capabilities, but they cater to different business models, pricing strategies, and branding goals.

Comparative Overview: Japan vs. China in Sauna Suit Manufacturing

Criteria	Japan Manufacturers	China Manufacturers (e.g., S-SHAPER)
