[Japan 🇯🇵]

In Thailand, wrong-way driving has become almost normal. We see police chasing them, but they never catch them all. But in Japan, almost no one drives the wrong way — whether car or motorcycle. Why? The answer is serious enforcement with real consequences.

Japan takes traffic laws seriously with a graduated penalty system — warnings, on-the-spot fines, license suspension, imprisonment — so no one dares challenge rules. Wrong-way driving on expressways makes this clear: about 200 cases annually (224 in 2023), with 17% leading to accidents. That’s low compared to Thailand, but Japan didn’t wait for numbers to rise. Since 2014, 98% of expressway interchanges nationwide have countermeasures — directional arrows, 3D optical illusions like obstacles, and wedge bumps hitting only wrong-way vehicles. In November 2024, they identified 188 high-risk spots needing additional measures by 2028, and they’re developing AI to detect wrong-way driving in real time.

Back home, motorcycles and cars driving against traffic is so common we don’t notice. Songkran 2026: 191 deaths in 5 days, 72.88% from motorcycle accidents. We don’t track wrong-way driving statistics separately — it’s just part of general accident numbers. The UN sent a special envoy to Thailand in September 2025. Toyota and Honda ran a campaign in February 2026. The problem remains.

Wrong-way driving risks every life on the road. We can change this. Start with real enforcement for motorcycles and cars. Safer streets will follow.
