30-Second Answer
Kumamoto, Chiba, Yamagata, and Tottori are Japan's four big watermelon (suika) producers. Each summer, each region hosts a "suika matsuri" with whole-watermelon lottery prizes, suika-wari (watermelon splitting) contests, all-you-can-eat sessions, and chilled suika juice stalls. Most festivals are free; even paid ones charge ¥500-2,000 for unlimited watermelon — quintessentially local events. Many visitors arrive in yukata, and some festivals end with fireworks. A calmer alternative to Tokyo's packed fireworks displays.

🌐 Visitor Support
Most rural summer festivals don't have full-time English staff, but city halls and tourism associations increasingly print English brochures. Google Translate and ¥3,000-5,000 in cash will see you through. Free shuttle buses run from the nearest station, so a car isn't required. Tottori, Kumamoto, and Tomisato in Chiba all work as day trips or overnights from Tokyo or Osaka. Food stalls almost never accept cards, so cash is essential.
