Highly Poisonous Mushrooms Proliferate on Mount Takao Amidst Unusual Weather Conditions
Highly poisonous kaentake mushrooms are appearing in large numbers on Mount Takao in western Tokyo, posing a significant risk to hikers and visitors. These bright red fungi, known for causing severe skin damage upon contact and being fatal if ingested, are flourishing due to unusually hot summer weather followed by prolonged autumn rainfall. Central Tokyo experienced 37 consecutive days of rain, the longest on record, creating ideal damp conditions for mushroom growth. Warning notices have been posted around the mountain, including near the cable car station, with signs in Japanese and English advising visitors not to touch them. Despite repeated removal efforts, new mushrooms continue to emerge, often in the same locations, attributed to underground fungal networks (mycelium) that remain in the soil. Experts, like university professor Koichi Inoue, confirm that this year's weather has been exceptionally favorable for fungal proliferation, and the danger extends beyond mountain trails to urban parks.
