Also known as Onioshidashi Park, this otherworldly landscape of black, craggy rocks was created from molten lava when Mt. Asama erupted in 1783. Walk among the rocks to see over 100 species of alpine plants and catch views of Mt. Asama, one of Japan's most active volcanoes. Mt. Asama Magma Stone Park is accessible from Tokyo by train and bus.
Reach Mt. Asama Magma Stone Park in around 2 hours from Tokyo Station by taking a shinkansen to Karuizawa Station, and then a bus. Alternatively, take a shinkansen to Takasaki Station. From there, transfer to a limited express train to Naganohara-Kusatsuguchi Station, then a local train to Manza-Kazawaguchi Station, followed by a 15-minute bus ride to Mt. Asama Magma Stone Park. The trip takes 2 hours and 30 minutes. A local train from Takasaki to Manza-Kazawaguchi Station is slightly cheaper, but adds an extra 30 minutes to the trip.
