The Dopamine Trap: The Truth About Gambling Hijacking the Brain's Reward System and the Current State in Japan

1. Introduction: The Era of "Online Winning Thrills"

Since the COVID-19 pandemic, an era has arrived where you can bet on slots and sports with just a smartphone. The convenience of being able to play anytime, anywhere has replaced the closing bell of pachinko parlors with the endlessly ringing sound of reels sneaking into our pockets. Social media is flooded with voices like "At 2 a.m., I felt like I could win it back with just one more spin" and "When I open my phone during a break, ads pop up."search.yahoo.co.jpsearch.yahoo.co.jp

2. What is the Brain's Reward System?

The human brain is equipped with a "reward system" to promote behaviors essential for survival, such as eating, communication, and reproduction. The mesolimbic pathway, which runs from the ventral tegmental area (VTA) of the midbrain to the nucleus accumbens, is central, and the release of the pleasure substance dopamine forms the learning of "wanting to do it again."homepagedaily.com

3. Gambling and "Dopamine Overload"

According to the article, gambling activities trigger nearly ten times the dopamine release compared to natural rewards. The release peaks not at the "moment of victory" but during the anticipation phase of "maybe I'll win next time," leading the brain to mislearn. This is the first step of the "hijack."homepagedaily.com

4. The Psychological Trick of Near Misses

Experiments have shown that even a "near miss," where the reels don't align by just one space, results in almost the same brain activity as a real win. Casino operators use algorithms that increase the frequency of near misses while maintaining statistical fairness, enticing another click of "just one more time."homepagedaily.com

5. Industry Design Strengthening the Addiction Loop

Smartphone notification sounds, flashing jackpot banners, countdown ads—all these are engraved in the brain as conditioned stimuli, pre-releasing dopamine through sight and sound alone. As a result, the state of "the most fun is before betting" continues, making it difficult to withdraw even when losses accumulate.

6. Plastic Brain Changes and the "Can't Stop" Mechanism

In the long term, the inhibitory function of the prefrontal cortex declines, and the sensitivity of the reward system dulls. Ordinary meals and hobbies no longer provide sufficient dopamine, leading to a progression of "tolerance" towards larger bets. Neuroscience research has confirmed that after approximately 90 days of abstaining from gambling, neural networks begin to reorganize.homepagedaily.com

7. The "Real Screams" Heard on Social Media

• "Spent money on online casinos until I was in debt, and before I knew it, my balance was zero."

• "I voluntarily banned myself from Maruhan, but my hands shake just seeing the exchange office."

• "Oppose IR. Stop it before the brains of young people are destroyed."

8. Social Debate Surrounding IR and Pachinko

In the IR development plan progressing on the Osaka Bay coast, "economic effects vs. addiction risks" are fiercely clashing. Mizuho Fukushima, a member of the Social Democratic Party, posted a strong statement opposing the increase of gambling addiction.search.yahoo.co.jp

9. Current Situation in Japan Seen Through Data

According to a survey by Asahi Shimbun, there are an estimated 3.37 million online casino users, with an annual betting amount reaching 1.2423 trillion yen. 46% of users have experienced debt, and over 40% are unaware of its illegality.asahi.com

10. Public Support and Legal Framework

The "Basic Act on Gambling Addiction Countermeasures," enacted in 2018, stipulates providing support at each stage of onset, progression, and recurrence. However, in reality, responses vary by municipality, and the lack of specialized medical institutions and insufficient awareness of consultation services are challenges.mhlw.go.jp

11. Practical Guide to Regaining Natural Rewards

CBT, exercise habits, creative activities, and community participation—these release dopamine "healthily" and readjust the reward system. Exercise, in particular, has a high immediate endorphin effect and is reported to have an immediate effect in alleviating withdrawal symptoms. It is effective in overcoming the 90-day "neural circuit reset" mentioned in the article.homepagedaily.com

12. The Necessity of Advertising and Technology Regulation

In the UK, restrictions on the timing of gambling advertisements and bans on targeting are advancing. Similar discussions have begun in Japan, but many online operators are based on overseas servers, making it difficult for regulations to keep up. The enforcement of AI censorship and mandatory age verification APIs is urgently needed.

13. Conclusion: Redesigning from the Perspective of "Protecting the Brain"

Dopamine is originally an important neurotransmitter that governs the joy of living. However, the gambling industry meticulously designs to artificially extract this source, exhausting our daily lives. Addiction is not due to "weak willpower," but a result of the brain's learning mechanism being rewritten. With an understanding of neuroscience and social solidarity, we can return to natural pleasures once again.
