Feared by locals but crucial to the ecosystem, the Habu viper is a nocturnal and highly venomous snake in Amami region.
The risk of encountering a habu increases on warm, humid nights (typically from June to October), especially when temperatures exceed 20°C which is also when creatures like frogs are most active. If you’re exploring at night, always follow your guide’s safety instructions and wear long pants and boots.
