What to know
- This is the third round of the Secret Box puzzle in Ebisugaoka Middle School.
- The keyword for this round is “sakura in full bloom” (cherry blossom imagery).
- You must slide panels on both sides of the box to isolate only the correct sakura symbols.
- The exact panels to show differ based on your chosen difficulty (Story, Hard, Lost in the Fog).
Right after completing the fruit and journal stages of the puzzle box, you’ll be tasked to show “Sakura in Full Bloom.” This solution is required to progress on the second floor of the school and is one of the most visually confusing puzzles due to flower symbol ambiguity.
Clues Hidden in Rinko's Letters
Rinko's three letters provide the puzzle's backbone, each unveiling after solving a prior layer.
The first envelope hints at "Exposing Sweet and Tart Fruits," the second at "Showing All the Journals," and the third—the focus here—at "Showing Sakura in Full Bloom."



These phrases aren't mere poetry; they direct you to specific symbols on the box's sliding wooden panels. In the game's narrative, Rinko was a former student whose writings echo the town's cursed history, blending personal loss with the encroaching floral infestation that defines Silent Hill f's aesthetic.
| Letter | Key Phrase | Corresponding Symbols |
|---|---|---|
| First Envelope | Exposing Sweet and Tart Fruits | Grapes (sweet) and lemon (tart) icons |
| Second Envelope | Showing All the Journals | Three stacked notebook symbols |
| Third Envelope | Showing Sakura in Full Bloom | Cherry blossom branches with five-petaled flowers |
This table outlines the progression, ensuring you track symbols across rounds.
When you reach the third round of the Secret Box puzzle, you’ll be given a clue referencing spring and blooming cherry blossoms. You’ll need to manipulate the box’s sliding panels to show only the sakura symbol(s). Getting this right will yield the second-floor classroom key and allow you to progress further in the story.
Below is a detailed step-by-step guide for each difficulty setting.
How to solve the Sakura in full bloom puzzle box
Step 1
Take the puzzle box from the desk and read the note referencing “Sakura in Full Bloom.” This is your clue for the round.

Step 2
Rotate the box to view all sides. There are usually three rows on each side that can be set to display flower symbols.

Step 3
Identify the sakura flower silhouette among the options. The sakura generally appear as small, five-petaled blossoms, sometimes with branches full of flowers rather than leaves.

Step 4
On the Story difficulty, only one unique sakura branch needs to be visible. On Hard difficulty, select all the panels with the full blossom sakura symbol. Be careful—other similar-looking flowers are present but only the true cherry blossom counts.

Step 5
Slide the panels so that only the sakura in full bloom symbols are visible on all faces of the box. Confirm your selection as soon as the symbols match the clue (the right side, third row for Hard mode).
Step 6
If solved correctly, the box will open, revealing the key and a new note for your journal, letting you progress to the Second Floor Classroom.

Solutions by difficulty
| Difficulty | Side 1 (Front) | Side 2 (Back) | Notes |
|---|---|---|---|
| Story | No change needed (the sakura is already in correct position) | Third Row | Only one sakura branch is needed in Story mode. |
| Hard | Middle Right | Top Right, Bottom Right | You may need to shift more panels to filter out other flowers. |
| Lost in the Fog | First Left Brown Row, Third White Row, Third Right Brown Row | First Left Brown Row | More complex, as more decoy options appear. |
After solving “Sakura in Full Bloom”
Once you successfully complete the sakura stage:
- The Secret Box will open fully, granting you the Second Floor Classroom Generic Key.
- You’ll then be able to access previously locked areas in the school and gather more clues for subsequent puzzles and the story.

Getting stuck and tips
If struggling with the symbols, observe the outlines carefully and compare with the journal’s hint illustration. Only the correct number of sakura blossoms in full bloom should be present when you confirm the selection, and avoid sliding past the correct set as the puzzle may “reset”.
Wrapping up your classroom escape
Solving the puzzle box is essential for continuing the Ebisugaoka Middle School scenario in Silent Hill f and is recognized as one of the game’s signature visual puzzles. Stay patient—the symbols can be tricky, and the right selection opens up new narrative routes in the game.
