Samurai Style Co., Ltd. Officially Launches "HookHack," a Video Ad Production Service Specialized in Acquisition from LPs in as Little as 5 Minutes

Samurai Style Co., Ltd. (Shibuya-ku, Tokyo; Representative Director & CEO: Keiji Hashimoto; hereinafter "Samurai Style"), which provides overseas expansion support and web marketing support, has developed "HookHack," a service that generates video ads from LPs in as little as 5 minutes and improves the accuracy of measure execution to generate sales differences, and officially launched it today.

This product was developed through joint offshore development by engineering teams in Japan and Indonesia, achieving a significant update from the beta version released in June 2025.

[Increasing Importance of Video Ads in the Acquisition Domain]

In recent years, the widespread adoption of LLM (Large Language Models) in web search has increased the long-term uncertainty of listing ads, which were traditionally the mainstay of acquisition measures. On the other hand, user touchpoints originating from social media and video platforms are expanding, and video ads are becoming increasingly important not only in the traditional awareness domain but also in the acquisition domain, aiming for purchases and applications.

Amidst these environmental changes, companies are required not only to produce videos but also to identify which appeals and expressions lead to sales and conversions, and to connect this to improvements.

[Planned and Developed Based on the Representative's Practical Marketing Experience]

Our representative, Hashimoto, has supported marketing strategy planning and execution focused on the acquisition domain based on business understanding, through his experience in both operating companies and web vendors, for a cumulative total of over 30 companies.

Through this practical work, he consistently confronted the challenge of how to identify the overlap between customer needs and the value provided by operating companies, and how to communicate it to lead to results. Especially in measures aimed at acquiring conversions, while differences in appeals and expressions can create significant differences in results, video advertising tends to have a relatively higher production burden compared to still image banners, making the barrier to entry high, and validation tends to be individual-dependent even after starting.

Based on this awareness of these challenges, our company planned and developed HookHack to lower the barrier to video ad production, improve the speed and accuracy of PDCA cycles, and support the identification of patterns that lead to results.

[What HookHack Aims For]

The value of previous production tools tended to be compared in terms of functional aspects such as "how much it costs to produce one" or "how much labor can be reduced." However, what advertisers truly seek is not the creative itself, but how much sales can be increased through the creative.

To achieve this, it is necessary to visualize the relationship between the constituent elements of video advertising, such as appeals and expressions, and performance indicators such as sales and CVR, and elevate this to decision-making that leads to results.

HookHack supports the visualization of the relationship between input and output in video advertising and the improvement of reproducibility in decision-making that leads to sales differences, through research of competitor LPs and ad expressions, generation of multiple appeal patterns based on analysis of other companies, and hypothesis testing in ad operations.

Through HookHack, our company aims to "create sales-differentiating video advertising marketing."
