Event Report: Held on Tuesday, July 14, 2026 – 'Secrets of Hyper-Local Business: Achieving 300M, 500M, and 1B JPY in Renovation Sales; 10B JPY Annual Revenue from a Single Store; 250 Monthly Inquiries Without Sales Staff'

The Japan Good Builder Association (headquartered in Minato Ward, Tokyo; Representative Director: Ryo Tajima; hereinafter 'JGBA') hosted the seminar titled 'Secrets of Hyper-Local Business: Achieving 300M, 500M, and 1B JPY in Renovation Sales; 10B JPY Annual Revenue from a Single Store; 250 Monthly Inquiries Without Sales Staff' on Tuesday, July 14, 2026, both in-person and online. The event welcomed 40 participants.

The seminar featured Takashi Kitagawa, President and Representative Director of Kitasetsu Co., Ltd., who revealed the company’s powerful hyper-local strategy that has achieved 1 billion JPY in annual revenue for four consecutive fiscal years with just one store based in Ota Ward, Tokyo.

Mr. Kitagawa emphasized that strictly limiting the service area to within a 30-minute drive—applying the Lanchester Strategy—has significantly boosted local brand recognition and highly efficient customer acquisition. To maintain repeat customers, who account for approximately 75% of sales, the company values analog touchpoints such as a 20-year-running newsletter and 500 handwritten birthday cards sent monthly. At the same time, it has introduced cutting-edge DX tools like AI-based estimation systems and centralized management platforms, enabling standardized operations and achieving a 'fully guaranteed two-day weekend' system.

Additionally, the implementation of a profit-sharing system—distributing all profits exceeding a certain threshold directly to employees—and health-focused management through the president’s daily homemade lunches for over 10 years have dramatically enhanced employees’ cost awareness and engagement. These practices were highlighted as key drivers behind the company’s strong organizational culture and sustainable growth.

Participants shared positive feedback: 'While many strategies were shared, the most valuable insight was that sustainable business is achieved by always putting people—customers and employees—at the center.' Another noted, 'In today’s digital marketing era, I was deeply impressed by their emphasis on analog engagement.'
