The eerie halls of Ebisugaoka Middle School in Silent Hill f are packed with unsettling puzzles, but few feel as deceptively simple as the Secret Box. Found in a second-floor classroom, this locked container stands between you and freedom. The door seals behind you, and the only way out is to solve this three-layered puzzle box.

This guide covers every detail you need to unlock the Secret Box across Story Mode, Hard Mode, and Lost in the Fog difficulty so you can claim the Second Floor Generic Classroom Key and continue your exploration.
How the Secret Box Works
The puzzle starts when you interact with the box sitting on a desk beside an Unopened Envelope. This letter provides cryptic hints tied to memories—references to sweet fruits, journals, and sakura blossoms.
- Each stage of the box corresponds to one of these keywords.
- Sliding panels on the box reveal symbols (fruit, books, flowers).
- To progress, you must match the correct symbols with the clue for that stage.
- After completing all three rounds, the box opens and grants you the key to the classrooms on the second floor.
Story Difficulty Solution
On Story Mode, highlighted words in the Unopened Envelope make the puzzle more straightforward. Only the white tiles of the box are interactive.
- Stage 1 – Sweet Fruits
- Reveal the Strawberry and the Cherry (located on opposite sides).
- Stage 2 – Journal
- Reveal all 3 Books (two on one side, one on the other).
- Stage 3 – Sakura
- Reveal the single cherry blossom branch.
Hard Difficulty Solution
On Hard Mode, the highlighted words are removed, and only the brown panels can be interacted with. The symbols are trickier, and the box offers more decoys.
- Stage 1 – Sweet Fruits
- Reveal Apple, Cherry, Cut Orange on one side.
- Reveal Strawberry, Pineapple, Grapes on the other.
- Stage 2 – Journal
- Reveal all 4 Books (three on one side, one on the other).
- Stage 3 – Sakura
- Reveal the two leafy cherry blossom branches, not the tree-like icons.
Lost in the Fog Difficulty Solution
The toughest version is Lost in the Fog, where every panel is active—giving you 20 symbols to sort through. Each stage requires more correct inputs than the others.
- Stage 1 – Sweet Fruits
- One side: Cherry, Strawberry, Berries, Pineapple.
- Other side: Cut Orange, Apple.
- Stage 2 – Journal
- Reveal 5 Books in total (four on one side, one on the other).
- Stage 3 – Sakura
- Reveal all 4 cherry blossom branches (three on one side, one on the other).
