I Saw Bears, Sperm Whales, and Red-crowned Cranes in Some of Japan’s Most Beautiful National Parks
"I saw Lake Akan’s crystal-clear caldera waters reflecting mountains and forests, and learned it is uniquely home to mysterious marimo algae balls (designated a National Special Natural Monument); scientists study these marimo—only Lake Akan is now reported to host the large marimo nearly 5 inches in diameter—and their formation remains a captivating local mystery tied to water currents." - Kristen Pope
