Japanese mystery stories for learners

Contos has 23 Japanese mystery series for learners, from beginner A1 to upper-intermediate B2: 5 at A1, 5 at A2, 9 at B1 and 7 at B2. The flagship, The Secrets of Sakura House, is written separately at each level, so the level figures add up to more than the total. The opening two chapters of each mystery are free.

What are the Japanese mysteries about?

Small puzzles in ordinary places. At A1 a young woman's cheap flat in Shibuya comes with a second key and a door that isn't on the floor plan, and a lonely data-entry worker starts receiving scented letters that say only that someone is watching her. At A2 a hot-spring inn has a room booked on the fifteenth of every month for a guest who never arrives, and a secondhand bookshop in Jimbōchō finds handwritten notes tucked into returned books:

「次は 『雨の 日の 地図』を 見てください」

"Tsugi wa 'Ame no Hi no Chizu' o mite kudasai."

"Next, look at The Map of a Rainy Day."

The Secret Notes of the Old Book Shop, chapter 1 (A2). The note is written in elegant brush handwriting. 『 』 are Japanese quotation marks for titles, and 〜てください is the polite request form.

From B1 the secrets reach back decades: a lighthouse in Kamakura that lights up after thirty years dark, a painting in a museum that has quietly been swapped, a sewing box full of fabric scraps that match old neighbourhood thefts.

Which Japanese words do mysteries repeat?

Mysteries are built from a small set of nouns that the plot keeps picking up again, which makes them good vocabulary practice: the same word in a new sentence each time. These are the ones that recur most across the free mystery chapters:

  • 秘密himitsusecret (in several series titles too)
  • 写真shashinphotograph, usually old and usually the clue
  • 手紙tegamiletter
  • 沈黙chinmokusilence, mostly from B1 upwards
  • 足音ashiotofootsteps, often in the last lines of a chapter
  • 鍵kagikey, or lock

Listen too for その とき (at that moment). In more than half of the free Japanese chapters it appears in the last two paragraphs, just before the cliffhanger. When you see it, the twist is coming.

How should I read a mystery in Japanese?

Slowly at the end, quickly in the middle. The middle of a chapter is usually scene-setting you can skim; the final paragraph is where every word counts. A good routine is to read the whole chapter once without tapping, then go back to the last paragraph and tap anything you're unsure of. Then guess, in a sentence of Japanese, who did it. Writing 犯人 は 〜 だ (the culprit is …) before you open the next chapter uses the vocabulary you just read.

Frequently asked questions

Which Japanese mystery is easiest?

The A1 mysteries. Try さくら荘の秘密 (The Secrets of Sakura House) or おばあちゃんの ないしょの お祝い (Grandma's Secret Celebration), which uses very few kanji and short polite sentences.

Are the mysteries scary?

No. They are cosy: missing objects, anonymous notes, family secrets and old photographs. There is no gore or violence on the page; the tension comes from what people are hiding.

How many Japanese mystery chapters are free?

52: chapters 1 and 2 of each mystery on this page, counting the flagship once per level. The rest come with Contos Premium.
