Ohtani used an OW64 at 15 to shape his future—a chart of 64 actions tied to one goal. OW64 helps you turn big goals into daily routines, track monthly progress, and stay consistent. Turn Big Goals Into Daily Action When Shohei Ohtani was 15, he didn’t rely on motivation or talent alone. He used a simple but powerful tool called an OW64—a handwritten chart that broke one big goal into 64 specific actions. OW64 brings the principles of that same goal‑clarity system into a modern app—so you can apply structure, focus, and consistency to your own goals. This isn’t about hype. It’s about doing the work—one clear step at a time. What Is OW64? OW64 helps you stop guessing and start progressing. You choose one meaningful goal, then break it down into: Clear focus areas Daily routines Trackable actions Monthly progress you can review and improve Instead of asking “Am I doing enough?” You can clearly see what you did, what worked, and what to adjust next. Why OW64 Works Most people don’t fail because they lack effort. They fail because their effort isn’t structured. OW64 helps you: Turn a big goal into clear daily actions Build consistency without burnout Track progress month by month Reflect, adjust, and stay on course You don’t need more motivation. You need a system that shows you what to do next. Key Features (Built for Real Progress) Goal → OW64 → Action Create your OW64 by breaking one goal into focus areas and routines—just like the original Harada method intended. Daily Routine Tracking Report your routines daily so consistency becomes visible, not vague. Monthly Progress Review Look back at what you did last month, identify patterns, and assess how close you’re getting to your goal. Community Visibility & Encouragement Share your progress with others using OW64. See how others structure their goals, receive encouragement, and celebrate milestones together. Milestones & Celebration Progress sticks when it’s recognized. Celebrate consistency, streaks, and effort—not just outcomes. Inspired by Shohei Ohtani’s Early System At age 15, Shohei Ohtani used the Harada Method OW64 chart—created by Mr. Takashi Harada—to map his goal, define responsibilities, and commit to daily action. OW64 is not the same handwritten chart. It is a modern app inspired by the same system of clarity, responsibility, and routine—adapted for students, athletes, and professionals today.
