Uchiyama Yasuji

The serialized manga from "Science for \[Year]" is back as an ebook after 40 years!

The story follows a group of boys, girls, and animal characters who travel the world in suitcases that transform into airplanes and submarines, while a group of doctors who have become separated from them follow in a balloon that transforms from a travel bag, and the group narrowly misses reuniting with them. The descriptions of each country are somewhat biased; while developed countries in Europe and America are depicted in considerable detail, the latter half is rushed, and countries in Africa and South America, in particular, are hardly introduced, partly due to the historical context of constant racial and ethnic conflicts at the time. Sales were not particularly strong (average of all titles) \[ 5 ] , and it went out of print soon after the new edition was published.

\*Due to circumstances, some illustrations and photographs are not included in the digital version. We appreciate your understanding. The "First Secret Series," which was first published in 1972 and remains immensely popular, is back as an ebook after 40 years! The first installment is "The Secret of What You Can and Can't Do" by Yasuji Uchiyama. In addition to the manga text, the manga that served as the basis for this story, originally serialized in "5th Grade Science," is included as a "special bonus."

The story follows the protagonist Korosuke, his cat Nyago, and his mouse Chusuke as they strive to solve various scientific mysteries.
