'The Strange Man From Underground'.
Nishioka Eiji was the creator of the undated pocket manga 'The Strange Man from Underground' ('Chitei no kaijin'). The SF story is undated and no publisher's info is known, but is presumably from the early 1950s and clearly inspired by Osamu Tezuka's 1948 manga 'The Strange Man from the Underground Country' and 'The World One Thousand Years Later'.
