The Rise of Shoplifting in Japan: A Simple Solution

1/4/2026, 4:16:11 AM

Growing Concerns Over Shoplifting

Shoplifting has increasingly become a significant issue in Japan, particularly exacerbated by the COVID-19 pandemic. Tomoo Okubo, a professor of criminal psychology at Kagawa University, has dedicated 16 years to studying this phenomenon. He asserts that the official statistics on shoplifting represent only a small fraction of the actual incidents occurring across the country. In Kagawa Prefecture, where Okubo resides, the region held the highest number of reported shoplifting cases in Japan for seven consecutive years until 2009.

Research and Strategies for Prevention

In response to the rising crime rates, Kagawa Prefectural Police sought Okubo's expertise to develop effective deterrents against shoplifting. His research involved engaging with various stakeholders, including offenders, students, parents, and shop owners, to understand the motivations behind theft. This comprehensive approach allowed him to identify key factors contributing to shoplifting behaviors.

Okubo collaborated with a professional shoplifting investigator to apprehend suspects and train retail staff in theft prevention techniques. One of the notable outcomes of this collaboration was the creation of a practical handbook aimed at preventing theft, particularly at self-checkout counters, which have become increasingly popular in retail environments.

A Friendly Greeting as a Deterrent

Through his extensive research, Okubo discovered that a simple, friendly greeting from store staff could serve as an effective deterrent against shoplifting. This approach emphasizes the importance of human interaction in retail settings, suggesting that a welcoming atmosphere may discourage potential thieves. Okubo's findings indicate that fostering a positive customer experience can play a crucial role in reducing theft incidents.

Criticism and Opposition

Despite the promising nature of Okubo's findings, some critics argue that relying solely on greetings may not address the underlying socioeconomic factors contributing to shoplifting. They contend that a more comprehensive strategy, including addressing poverty and providing social support, is necessary to tackle the root causes of theft.

Official Statements & Responses

In light of the growing concern over shoplifting, Kagawa Prefectural Police have expressed their commitment to collaborating with researchers like Okubo to implement effective strategies. They recognize the need for innovative solutions to combat this issue, particularly as retail environments evolve.

What's Next

As shoplifting continues to rise, further studies and initiatives are expected to emerge, focusing on both preventative measures and addressing the socioeconomic factors that contribute to theft. The effectiveness of Okubo's friendly greeting strategy will likely be monitored and evaluated as part of ongoing efforts to curb shoplifting in Japan.
