46年前，日本京都府長岡京市發生一起至今仍令人毛骨悚然、無法解釋的懸案，被稱為「長岡京三女子離奇遇害案」。事件發生在長岡京市郊區的一片竹林深處，三名少女閨蜜相約上山採蕨菜，原本只是平常的春日郊遊，卻最終演變成一場血腥悲劇。據警方與後來的調查資料顯示，其中兩人慘遭殺害，身體多處受傷，腳筋幾乎被斬斷，手段極為殘忍，僅有一人倖免於難，成功逃出現場。

然而，逃生者的幸運並未持久。五年後，她在不同地點遭遇了同樣手法的攻擊，最終也不幸身亡。案件最為詭異的一點在於，三人遇害現場留下的血液皆屬同一血型，而兩起案件的作案手法高度相似，使得案件更添神秘色彩。這不僅引發警方的高度關注，也在民間引起無數揣測與恐慌：這究竟是人性的極端惡行，還是某種無法言說的神秘力量在作祟？

案件調查極其困難。據報導，當時出動的警力多達25,000人，調查過程中收集大量線索，詢問了數百名證人，但最終仍未能確定任何嫌疑人。有觀點認為，凶手可能早已離開長岡京，甚至可能已死於意外；也有人推測，這背後或許隱藏著某種精心掩蓋的陰謀與利益關係；更有民間傳聞低聲流傳——竹林中潛伏的，或許並非普通人類。

1994年5月24日，案件的訴訟時效正式到期，即便日後有人揭示真凶身份，也無法再依法提起刑事訴訟。這起案件因此成為日本刑事史上一個長期未解的懸案，不僅因其殘忍的作案手法引人震驚，也因其種種難以解釋的細節，在民間流傳成一個充滿詭秘與恐怖色彩的都市傳說。至今，長岡京的這片竹林仍被視為陰森之地，偶爾的風聲與林間回響，似乎都在提醒人們，那段血腥而神秘的歷史從未真正消逝。

Forty-six years ago, a chilling and still-unsolved case shook Nagaokakyo City in Kyoto Prefecture, Japan. Known as the “Nagaokakyo Three Women Mysterious Murder Case,” it began as a seemingly ordinary spring outing. Three close female friends went up into a bamboo grove on the outskirts of the city to collect fern shoots, but the trip ended in a gruesome tragedy. According to police reports and later investigations, two of the women were brutally murdered, suffering multiple wounds with their tendons severed, while the third managed to escape. The method of killing was exceptionally violent and precise, leaving an indelible mark of horror on the community.

Tragically, the surviving woman did not remain safe. Five years later, she encountered a nearly identical attack and ultimately lost her life as well. What made the case even more mysterious was that the blood found at the crime scenes in all three murders belonged to the same blood type, and the methods used in both incidents were strikingly similar. This led investigators and the public alike to speculate: was this the work of human evil taken to an extreme, or was there some inexplicable, almost supernatural force at play?

The investigation proved extraordinarily difficult. Reports indicate that as many as 25,000 police officers were involved, hundreds of witnesses were interviewed, and countless clues were collected—but no suspect was ever conclusively identified. Some theorists suggested that the killer may have left Nagaokakyo long ago or even died in an accident. Others speculated that the murders were part of a carefully concealed plot tied to deeper motives, while some local rumors whispered that whatever lurked in the bamboo grove may not have been entirely human.

On May 24, 1994, the statute of limitations for the case officially expired. Even if the perpetrator were identified afterward, no criminal charges could legally be pursued. As a result, the Nagaokakyo Three Women case remains one of Japan’s most notorious unsolved crimes. Beyond the brutality of the murders themselves, the mysterious circumstances—including the repeated blood type and the precise, eerily similar methods—have fueled ongoing speculation and made the case a haunting part of local lore. Today, the bamboo grove where the murders occurred is still regarded with a sense of foreboding, and the wind rustling through the trees seems to remind visitors that the dark history of that bloody and enigmatic night has never truly faded.
