SHINKA Corp. Completes 5-Book Customer Acquisition Series for Stores and Salons—Offers Free Original AI Diagnosis and 33,000-Yen Seminar to All Buyers

Customer Acquisition and Promotional Textbook Series for Stores and Salons (Now Available Nationwide and on Amazon)

SHINKA Corporation (Headquarters: Yokohama, Kanagawa; CEO: Yukie Oda) has launched a "Buy 5 Books Campaign" to commemorate the completion of its five-book series on customer acquisition and promotion, produced by company director Sayo Tanaka and targeted at store and salon owners.

Readers who purchase all five books through nationwide bookstores or Amazon will receive two exclusive benefits: an AI-powered "Customer Acquisition Priority Diagnosis" developed by SHINKA's engineers, and a complimentary invitation to the "Customer Acquisition Master Seminar" (normally priced at 33,000 yen including tax), scheduled for September 8, 2026.

Background: Diversification of Customer Acquisition Methods and the "Where to Start" Dilemma

In recent years, the range of customer acquisition methods available to stores and salons has rapidly expanded. Tools such as Instagram, LINE Official Accounts, Meta Ads, MEO (Map Engine Optimization) using Google Maps, and LLMO (Large Language Model Optimization) for AI search continue to grow in number. However, small business owners frequently express the following concerns:

- Posting daily on Instagram but failing to achieve stable customer acquisition - Having created a LINE Official Account but not knowing how to use it effectively - Hesitating to try Meta Ads due to uncertainty and fear - Continuously postponing Google Maps optimization (MEO) - Hearing the term LLMO but not knowing where to begin

With the rise of the AI search era, relying solely on individual tactics like Instagram or paid ads is increasingly ineffective. To address this, SHINKA has completed the planning and publication of a series that teaches how to combine and implement these five key customer acquisition methods: Instagram, LINE Official Accounts, Meta Ads, MEO via Google Maps, and LLMO for AI search.

The series has received significant acclaim, ranking No. 1 in multiple Amazon bestseller categories including "Marketing," "Small and Medium Enterprise Management," "Advertising and Promotion," and "Internet and Web Development." More than two months after release, the books continue to be purchased through nationwide bookstores and Amazon.

Guided by the principle that it's not enough to learn each method individually—businesses must combine them in the right order—SHINKA launched this campaign.

Overview: "Customer Acquisition and Promotion Series for Stores and Salons" (5 Volumes)

Campaign Benefits for Purchasing All 5 Books

【Benefit 1】AI-Powered "Customer Acquisition Priority Diagnosis"

Based on business type, current customer acquisition status, and strengths, an original AI tool developed by SHINKA's system engineers will individually diagnose the optimal starting point and implementation sequence across the five channels: Instagram, LINE Official, Meta Ads, MEO, and LLMO.

Specifically, the AI analyzes:

- The most effective initial customer acquisition tactic - Channels that need strengthening - The next recommended step

This eliminates uncertainty about where to begin and provides a customized customer acquisition roadmap.

Producer Comment from the 5-Book Series

"We've heard from many business owners that they're overwhelmed by the growing number of customer acquisition methods and don't know where to start. This series was designed not only to provide in-depth knowledge of each of the five methods but also to help readers identify the right sequence for their own business. By combining the AI diagnosis and seminar, we aim to go beyond just reading—delivering an experience that leads to real customer acquisition results.

Our goal isn't to add more information, but to help more people choose the right customer acquisition methods for their unique business. We'd be delighted if this series becomes the first step toward that goal."

Sayo Tanaka, Director, SHINKA Corporation
