The 'Uchu-ichi' (Easiest in the Universe) series of university entrance exam preparation books, published by Gakken Inc. (a subsidiary of Gakken Holdings Co., Ltd.), has surpassed 1.11 million copies in cumulative circulation. A new jacket design was unveiled on July 17, 2026.

Concept: The 'Uchu-ichi' series is built on the concept of 'conveying difficult content in a way that anyone can understand.'

Three reasons for the series' widespread support:

1. Navigation through illustrations and characters: Colorful characters guide students through the content, allowing them to learn as if they were reading a story.

2. Meticulous diagrams: The format features detailed explanations on the left page and summarized illustrations or diagrams on the right, enabling both intuitive and fundamental understanding.

3. Thorough output support through exercises: The series includes substantial practice problems using actual university entrance exam questions, supporting students from initial comprehension to practical application.

The following titles are currently available:

- 'Easiest in the Universe High School Chemistry: Theoretical Chemistry (Revised)' - 'Easiest in the Universe High School Chemistry: Organic Chemistry (Revised)' - 'Easiest in the Universe High School Chemistry: Inorganic Chemistry (Revised)' - 'Easiest in the Universe High School Physics: Mechanics & Waves (Revised)' - 'Easiest in the Universe High School Physics: Electromagnetism, Heat & Atoms (Revised)' - 'Easiest in the Universe High School Biology: Basic Biology (Revised)'
