Kegare, Kamidana Sealing, and Purification After Death in Shinto

What Kegare Actually Means

Kegare is usually translated as "spiritual pollution" or "impurity," but the concept is more precise than those English words suggest. Etymologically, kegare comes from ki-gare — the withering or exhaustion of musubi, the essential life-force energy within a family unit. When someone dies, that life force is severely depleted. The household's spiritual equilibrium is disrupted.

This matters operationally because Shinto shrines are built as loci of absolute purity, fertility, and generative energy. Kegare must never enter a shrine. This is why Shinto funerals never take place at a shrine — they're held at private homes, community centers, or commercial funeral halls. And it's why the household kamidana (god shelf) must be sealed the moment death occurs.

How to Seal the Kamidana (Kamidana-Fūji)

The kamidana-fūji should be performed immediately after the death, before the kamidana is used again. Here is the exact procedure:

Who does it matters. The person who seals the kamidana must be someone who does not carry the direct kegare of the death — such as a distant relative who doesn't live in the household or the funeral director. The chief mourner (moshu) does not perform the sealing; the kamidana remains closed and unused during the entire 50-day mourning period.

Step 1: Remove all daily food and water offerings from the kamidana shelf.

Step 2: Close the wooden doors of the miniature shrine.

Step 3: Tape a sheet of plain white paper (hanshi) across the front of the altar, covering the entire facade.

Step 4: Secure the paper with tape only. Never use metal tacks, pins, or nails — driving metal into the sacred wood of the kamidana is considered deeply disrespectful to the kami.

The kamidana stays sealed for the full fifty days of kichu (active mourning). No prayers, offerings, or worship at the kamidana during this period.

What Happens If You Forget

Families sometimes delay or forget the sealing, especially in the chaos of the first hours after a death. The theological concern is that kegare contacts the pure kami housed in the kamidana, causing spiritual distress to both the deities and the household.

If you realize the kamidana wasn't sealed promptly, do it immediately — even if it's been hours or a day. The sooner the better. Have someone without direct kegare perform the sealing. Consult the officiating priest about whether any additional purification is needed. In practice, priests are compassionate about honest mistakes made during acute grief.

Purification Salt (Kiyome-Shio) at the Door

After attending a funeral or cremation, mourners sprinkle purification salt (kiyome-shio) before entering their homes. The salt is typically provided by the funeral director in small packets as guests leave the service.

The purification is performed at the door: returning mourners sprinkle salt before entering the home. At the kika-sai (return-home ceremony) at the end of the funeral day, follow the priest's or funeral director's instructions for the exact procedure.

Home Purification After the Coffin Departs

After the hakkyu-sai (coffin departure), the room where the body rested requires purification. The funeral director's team typically handles the physical cleaning, but the ritual cleansing — called hakkyugo batsujo no gi — is performed by the priest using water, salt, and prayers. The temporary bedside altar is dismantled and replaced with a clean altar to house the reiji (spirit tablet) when it returns from the cremation.

Unsealing the Kamidana on Day 50

The gojunichisai (50th-day memorial) marks the end of active kegare. After the priest completes the ceremony:

1. The family cleanses themselves with purification salt
2. The white paper is carefully removed from the kamidana
3. Fresh offerings of water, rice, salt, and sake are placed on the shelf
4. Daily worship resumes

The reiji tablet is permanently moved to the soreisha (ancestral shelf), positioned physically lower than the kamidana or to its left — ensuring ancestral spirits are not placed at equal rank with the high celestial kami.

Understanding kegare isn't just theological knowledge — it drives every logistical decision in a Shinto funeral, from venue selection to who can touch which objects. The Shinto Funeral Guide covers each purification step with visual diagrams so nothing gets missed during a period when clear thinking is hardest.
