    Gunma Pref. Agatsumaguntsumagoimura Kambara 1053
    This beautiful scenery was created from the lava that flowed out and spread when Mt. Asama had its giant eruption in 1783. The sight of the giant lava boulders scattered around makes for an impressive sight. In spring the lovely alpine plants bloom in profusion, while visitors can enjoy the changing leaves in the fall. The contrast with the deep black earth is indeed a sight to behold.

    どこを見ても溶岩に囲われていて、自然の凄さや強さを感じることができる場所でした。 景色も良く30分ほど歩きました。 一度は訪れるべき、おすすめの場所です。 I drove there at late February. There is nice view and I felt the power of nature. I walked for about 30 minutes there...
