About 30-Second Reading

Practise reading Japanese and Korean

30-Second Reading Detective helps English-speaking readers practise for Japanese and Korean books. Choose Japanese or Korean for the story, question and answer choices, with hints and explanations in English. Its four categories are Feelings, Motives, Clues and Perspective.

Opening the full story reveals the text and choices and starts a 30-second reading timer. Thirty seconds is an approximate reading time, not a deadline for your answer. You can keep reading and thinking after it reaches zero.

Questions and explanations

These short stories are original works created by DuraRing for this content. Characters and events are fictional, and the stories are not quotations from published books.

Each question asks you to choose the most natural of three answers using words and actions in the text. The explanation identifies the passages that support that answer. Read a character’s feelings in the context of the story rather than relying on general assumptions.

Difficulty stars are a guide within this content, not a school grade, examination level or measurement of reading ability. The reading exercises are in Japanese and Korean. The English edition provides guidance in English while keeping the story and answers in your chosen reading language.

Images and AI

The app introduction distinguishes illustrative interfaces from actual app screens. AI-generated images shown in the app help readers imagine a scene; they are not evidence for an answer or for the story itself. Compare AI explanations with the original text.
