New Release: Sales Know-how Extracted from 30,000 Meetings to Win Over Clients in the First 3 Minutes!

Diamond, Inc. (Shibuya, Tokyo) launched a new book for sales professionals titled 'Why Do You Sell in 3 Minutes? How to Use Time More Effectively Than Sales Talk' on May 20, 2026.

From the moment you say 'Nice to meet you,' you have only three minutes. It might sound surprising, but the success or failure of a sales meeting is often decided within this brief window. No matter how superior the product or how detailed the presentation materials, failing to capture the client's heart in the opening minutes drastically reduces the closing rate. Conversely, mastering these three minutes ensures that the subsequent negotiation proceeds smoothly, often leading to clients requesting the deal themselves.

This book systematizes the '3-minute method' derived from author Takuma Otsubo's experience in over 30,000 negotiations. Otsubo, who was once extremely shy, established this method based on his experience at McDonald's. The techniques are highly reproducible for anyone. At Japan Design, Inc., where Otsubo serves as CEO, this method has helped employees reach annual sales of 100 million yen within just two years of joining the company, significantly boosting overall organizational closing rates.
