Teishisei (低姿勢) refers to a posture of humility and attentiveness. In Japanese business culture, it reflects an approach grounded in respect, careful listening, and steady effort rather than assertion. This principle guides how we work and how we engage with our clients.

We support established eCommerce brands from outside Japan as they enter and grow within the Japanese market. Our role is to help clients navigate a market that values trust, consistency, and long-term presence. Rather than offering standardized solutions, we focus on understanding each brand’s circumstances and objectives before determining an appropriate course of action.


Our team is operator-led. In addition to client work, we maintain and manage our own eCommerce operations in Japan. These internal shops serve as practical environments for ongoing observation and refinement. Through daily operation, we remain closely connected to changes in consumer behavior, platform dynamics, and performance conditions. Insights gained through this work inform our recommendations, which are reviewed and updated regularly to remain relevant.


We believe that success in Japan is rarely the result of rapid expansion or aggressive tactics. Instead, it is often achieved through careful preparation, thoughtful localization, and incremental progress. For this reason, we place emphasis on clarity, operational stability, and alignment with local expectations.


Teishisei works with a limited number of clients at any given time. This allows us to remain attentive and involved, and to approach each engagement with the consideration it requires. We view our work as a partnership, grounded in mutual understanding and a shared long-term perspective.


Our intention is not to impose a formula, but to support measured growth through steady learning and respectful execution. This is the posture we take toward the market, and toward those we work with.
