Shinto Posthumous Name (Shigō) vs Buddhist Kaimyō — Cost and Meaning

One of the most emotionally charged expenses in a Japanese funeral is the posthumous name. In the Buddhist tradition, families may pay substantial temple donations for a high-ranked kaimyō (戒名) — and the price directly correlates with the perceived spiritual prestige of the name. For families choosing a Shinto funeral, this separate cost category disappears.

How Kaimyō Works (Buddhist)

A kaimyō is a Buddhist "precept name" given to the deceased by the temple priest. The name is inscribed on the lacquered spirit tablet (位牌, ihai) that sits in the family butsudan altar.

What makes the system contentious is the pricing. Temples assign kaimyō in ranked tiers, with higher-prestige names commanding dramatically higher fees:

Higher-ranked names involve larger temple donations; the exact amount depends on the temple and rank.

The justification is that higher-ranked names reflect greater devotion and bring the deceased closer to enlightenment. Critics — including reformist Buddhist clergy themselves — point out that the system effectively prices spiritual status, creating a hierarchy of the dead that tracks wealth rather than piety.

How Shigō Works (Shinto)

The Shinto posthumous naming system operates on an entirely different principle. The shigō (諡号) — also called okuri-na (贈り名) — is a systematic honorific assigned automatically by the presiding priest based on two factors alone: the deceased's age at death and their gender. There is no tiered pricing, no negotiation, and no spiritual hierarchy.

The age cutoffs are convention-dependent; the following categories and alternatives are used:

The officiating priest determines the exact form of the shigō/okuri-na under the applicable age-and-gender convention. Ask how the name will be written and formally recorded.

The name is inscribed on the plain, unlacquered reiji (霊璽) spirit tablet that is enshrined in the family mitamaya (ancestral spirit shelf). No fee is charged beyond the priest's overall saishiryō honorarium for the funeral service.

Why the Difference Matters Financially

For a family on a moderate budget, the shigō system eliminates a separate kaimyō line item, while the overall saishiryō still applies. The theological reasoning is coherent: Shinto views the deceased as becoming a protective household deity (祖霊, sorei) regardless of name rank, so a hierarchical naming structure would contradict the tradition's own metaphysics.

This financial saving is one of the practical reasons families cite for choosing a Shinto funeral, alongside the simpler altar requirements and the absence of expensive incense ceremonies.

What About Families With Both Traditions?

In Japan's syncretic religious landscape, many families maintain both a kamidana (Shinto god shelf) and a butsudan (Buddhist family altar). When such a family chooses a Shinto funeral, the deceased receives a shigō — no kaimyō is needed or appropriate. If the family later also holds a Buddhist memorial service at their temple, the temple may assign a kaimyō for that specific Buddhist context, but this is separate from the Shinto proceedings.

The critical point: do not let a funeral director suggest that you need both. The Shinto shigō and the Buddhist kaimyō serve the same function in their respective systems. Paying for a kaimyō when the funeral is Shinto is spending money on a name that will not appear on the reiji tablet and serves no purpose within the ceremony you are actually conducting.

The Shinto Funeral Guide covers the shigō system in full, including the exact wording to use when the priest asks for the deceased's biographical details, and how the name is formally announced during the senrei-sai spirit-transfer ceremony.
