Senrei-Sai Spirit Transfer, Reiji Tablet, and Mitamaya in Shinto Funerals

The Most Dramatic Moment of a Shinto Funeral

The senrei-sai is the theological centerpiece of the entire shinsosai. Held on the evening of the first day — typically after the tsuya-sai wake — this ceremony transfers the deceased's soul from the physical body into the reiji, a plain wooden spirit tablet that will house the ancestral spirit permanently.

Everything that precedes the senrei-sai (the body preparation, the makura-kazari altar, the wake) is preparation. Everything that follows (the main funeral, cremation, memorial rites) assumes the spirit now resides in the reiji. If the senrei-sai fails to properly anchor the soul, the entire subsequent ritual structure is theologically compromised.

The Darkness Requirement

The senrei-sai must be conducted in complete darkness. The lights in the funeral hall are extinguished, and guests should put away phone screens. The darkness symbolizes the formless, liminal state of the soul as it transitions between physical existence and spiritual permanence.

Guests should be warned in advance. The sudden plunge into total darkness is startling if you're not expecting it, and the natural instinct to reach for a phone flashlight must be suppressed. The ceremony lasts only a few minutes, but those minutes are meant to feel disorienting — a sensory parallel to what the transitioning soul experiences.

The Keishi Vocalization

In the darkness, the priest chants the senreisai-shi — a prayer specific to this ceremony — and then produces a sustained, low, vibrating vocalization called the keishi. This continuous "Oooh" sound serves as an acoustic guide, drawing the spirit out of the body and anchoring it into the reiji.

The keishi is not a prayer or a chant in the conventional sense. It functions as a sonic bridge — the priest's voice becomes the connection between the material and spiritual realms. The sound fills the dark room and creates a palpable shift in atmosphere that even skeptical attendees describe as genuinely affecting.

The Reiji (Spirit Tablet)

The reiji — also called mitamashiro — is a simple, unlacquered wooden tablet that acts as the physical vessel for the ancestral spirit. In stark contrast to the ornate, gilded, lacquered Buddhist ihai, the reiji remains deliberately plain. The unadorned wood represents the pure, unembellished state of the ancestral spirit.

During the fifty-day mourning period, the reiji sits on a temporary home altar where it receives daily offerings. After the gojunichisai ceremony on day fifty, it moves permanently to the soreisha (household ancestral shelf).

If fresh sakaki and proper materials are unavailable — common in diaspora settings — the priest may approve a simplified reiji made from a clean piece of white paper inscribed with the deceased's details. The function remains the same.

Norito — The Prayers of a Shinto Funeral

Unlike Buddhist sutras, which are standardized texts chanted in classical Chinese or Sanskrit translation, Shinto norito are composed in classical Japanese and personalized to the deceased. The priest's prayers during the main sojo-sai funeral service recount the deceased's life achievements, character, and family lineage. They introduce the spirit directly to the local kami and the ancestors already enshrined in the household soreisha.

The saishi (eulogy prayer) is the longest and most personal. It names specific accomplishments, relationships, and qualities of the deceased. Family members may be consulted beforehand about what the saishi should include.

Attendees are not expected to chant along or recite anything. The priest handles all liturgical vocalization. Your role during the norito is respectful silence and attention.

The Mitamaya (Ancestral Shelf)

The mitamaya — also called soreisha or tamaya — is the permanent household altar where the reiji tablets of all family ancestors reside. It is structurally distinct from the kamidana (god shelf):

Positioning: The mitamaya must be placed physically lower than the kamidana, or to its left. Ancestral spirits hold an honored but subordinate position to the celestial kami — placing them at equal height would violate the spiritual hierarchy.

Offerings: Daily water, rice, salt, and sake. Never incense — incense burning at a Shinto ancestral altar is a Buddhist practice with no place in Shinto worship.

Appearance: Plain wood construction, often with a small door or curtain. No gilding, no lacquer, no Buddhist imagery.

After the gojunichisai, when the reiji is permanently transferred to the mitamaya, the temporary altar is dismantled. From this point forward, the deceased is honored not as someone being mourned but as a protective ancestral deity watching over the household.

Why This Matters Practically

Understanding the senrei-sai sequence helps you prepare emotionally for the most intense moment of the service, coordinate with the priest about when lights will be extinguished (important for elderly or anxious attendees), and properly set up the temporary and permanent altar arrangements.

The Shinto Funeral Guide includes detailed instructions for both the temporary altar setup and the permanent mitamaya arrangement, so the transition on day fifty goes smoothly.
