What to know

  • The key to Sakuko’s mailbox appears during the second visit to Ebisugaoka (Fog Town).
  • It’s located near Sennensugi Shrine, next to rocks and a letter from Sakuko’s mother.
  • After grabbing the key, backtrack to Sakuko’s house and use it on the mailbox next to the front door.

Where to find Sakuko's mailbox key in Silent Hill f

The key becomes available during your second foray into Ebisugaoka (often referred to as the “second visit” of the Fog Town area). It is situated near the Sennensugi Shrine, north of Sakuko’s residence. Here's how to get to it:

How to reach the Sennensugi Shrine

Step 1

From Sakuko’s home area, head north along the pathways.

Step 2

At a fork or divergence, take the left path and continue forward until you reach the shrine grounds.

Step 3

Look to the left side of the shrine entrance gate. There, near rocks and a gravestone, you’ll find the mailbox key along with a letter from Sakuko’s mother.

This letter adds contextual lore about Sakuko’s condition and the eerie voices she hears.

How to use the key and what rewards it unlocks

Once the key is obtained, players must backtrack all the way back to the start of Ebisugaoka, moving toward the General Store and then northwest through an alley to find Sakuko’s house.

The mailbox to be opened is next to her front door.

Using the key on the mailbox grants two things: the Omamori Spider, an item that significantly reduces weapon durability consumption for light attacks...

...and a letter from the hospital containing more story details.

Opening the mailbox also unlocks the "A Federal Offense" trophy, which is missable if the player skips this step during the second visit to Ebisugaoka.

Tips for safely obtaining and using the mailbox key

  • Be aware of enemies along the way while backtracking; some can hinder progress, so prepare to either evade or fight.
  • Do not miss picking up the key during the second visit to Ebisugaoka. It cannot be revisited later in the playthrough.
  • Memorize or mark the return route to Sakuko’s house for faster navigation through alleys and paths.
  • Interact with the mailbox immediately upon return to secure the trophy and item before progressing further.

This mailbox key puzzle is a blend of exploration and backtracking within the eerie atmosphere of Silent Hill f, rewarding players who pay attention to their surroundings and story details with useful items and achievements.
