1️⃣ Humble Bunny — Flipping the “Japan Is Hard” Narrative Most international brands think: “Japan is complicated.” “Consumers are different.” “Performance is always lower.” They’re not wrong — Japanese CVR is often ~35% lower than global averages But that’s not a reality of a "sleeping" Japanese market: it's an endemic of underperforming and disconnected marketing strategies. At Humble Bunny, our mission is to elevate businesses out of the 96.9% that underperform in Japan and into the top 3.1% We’re here to prove one thing: When you apply the right structure, psychology, and localization toward conversion (not just translation), Japan becomes predictable, measurable, and scalable 2️⃣ Our Average Performance (Not Cherry-Picked Case Studies) We track averages because testimonials can be faked — real, quantified performance can’t Here’s what our Clients are achieving on average... - 5.7x average lead generation increase (across our service-based Clients) - 5.8x average sales increase (across our EC/product-based Clients) - 91% average CVR lift - 51.2% average reduction in customer acquisition costs - 95.5% contract renewal rate We publicly track our averages because Clients like you want to know if we're actually consistent. We think the answer is 'Yes'. Moreover, if we underperform your project, those averages will go down. That’s real skin in the game and real incentive for us and our staff to make sure we do well on you! 3️⃣ Our Frameworks are our Advantage We don’t “try tactics.” We build, rebuild, train, and retrain around systems 🔹 LocaRISE® & The 8 Lenses of Japanese consumer buying decision We built and quantified a proprietary formula for how Japanese consumers achieve confidence and then make the decision to buy. This is not just “pretty localization", this is conversion-focused localization. 🔹 TrueVP® and TrueCopy™️ - Structured Ad & Copy Frameworks 🔹 TrueTrack® - Data design and the 3/2/1 Analysis System 4️⃣ Free Offer — Let’s Pressure-Test Your System If you’re operating a website in Japan, send it to us and we'll provide a light audit against the Lenses of LocaRISE® to identify: 1. What messages are distinctly missing 3. Where Japan-specific psychology is missing 4. What to fix first for the biggest lift If Japan has felt “hard,” it’s usually just a structure problem. Let’s fix that.
