  • 🏆 Winner of Shopify Partner of the Year 2025 Japan

    “Shopify Partner of the Year 2025 Japan” recognizes the most outstanding achievements within Shopify’s partner ecosystem in Japan.

    Tsun received the Ecosystem App Developer of the Year award — the highest honor, given to the app development partner that has contributed most to expanding the Shopify ecosystem through public apps widely adopted by merchants in Japan.

  • 💎 Japan’s First, and Most, Marks of Highest Quality

    Our Shopify apps were the first from a Japanese company to earn “Built for Shopify,” Shopify’s official badge for the highest-quality apps. Today we hold the badge for seven apps — more than any other company in Japan.

    “Built for Shopify” is granted only to apps that meet Shopify’s highest standards for speed, ease of use, and the value they deliver to merchants.

  • 📈 Trusted by Over 15,000 Stores

    By continuously incorporating the real feedback and operational know-how we receive from so many merchants, our apps keep evolving into tools that are genuinely useful in the field. We remain committed to prioritizing “voices from the field” as we continue delivering more convenient, high-quality apps.

    Stores built to sell, easy to run, and tied directly to results

    Proven tactics plus speed, to uncover each store’s own growth drivers

    We start with proven tactics that support growth reliably. From there, rapid cycles of hypothesis and testing let us identify the growth drivers unique to your store early and accelerate from there.

    📱 Shopify App Development

    High-quality, user-driven apps that solve real e-commerce challenges

    We were the first Japanese company to earn “Built for Shopify,” Shopify’s official badge for the highest-quality apps, and our apps have since grown to more than 15,000 stores.

    By feeding the practical knowledge we gain from store development and marketing support straight into our product work, we deliver apps that are genuinely useful in day-to-day operations, at a consistent level of quality.
