Japanese Kaimyo — Posthumous Buddhist Names and What They Cost

Why the Kaimyo Exists

In many Japanese Buddhist sects, a temple priest may bestow a kaimyō (戒名) — literally "precept name" — during the funeral service. It is a religious name associated with the person's relationship to Buddhist rites, not a legal requirement, and the exact practice varies by sect. The name typically consists of two to six Chinese characters chosen to reflect the deceased's personality, virtues, or life achievements, bracketed by rank titles that indicate spiritual status.

The practice originates from the monastic tradition where new monks received a dharma name upon ordination. Over centuries, this was extended to lay practitioners at death, creating a system where the name's rank — and its associated fee — became one of the most significant costs of a Japanese funeral.

The Rank System and Pricing

Kaimyo names are organized into tiers, each with progressively more prestigious titles appended before and after the core characters. Prices vary by temple, region, and the family's relationship with their bodaiji (family temple), but the general structure looks like this:

The most basic rank, Shinshi (信士) for men or Shinnyo (信女) for women, costs roughly ¥100,000 to ¥300,000. The mid-tier Koji (居士) or Daishi (大姉) ranges from ¥300,000 to ¥500,000. The prestigious Ingo (院号) names — which include the prefix In (院) denoting temple-grade status — start at ¥500,000 and can exceed ¥1,000,000. The most elevated names, historically reserved for feudal lords and major temple patrons, can reach several million yen.

These fees are technically voluntary "donations" (ofuse) rather than fixed charges, which creates awkwardness. Many families feel pressured to select a higher rank to demonstrate filial respect, especially when relatives and neighbors will see the name displayed on the memorial tablet (ihai) at the altar and engraved on the gravestone (sotoba).

What Happens If You Decline

Some modern Japanese families, particularly those without a strong temple affiliation, choose to forgo the kaimyo entirely and use the deceased's secular name. Whether that is workable depends on the temple and family grave's practices, so confirm them before declining. Family members may view the decision as disrespectful. A memorial tablet at the household butsudan (Buddhist altar) may traditionally display the kaimyo rather than the secular name.

An increasing number of families are negotiating directly with their temple priest to receive a simpler name at a lower cost, especially in urban areas where temple relationships are weaker. Some priests have responded by publishing transparent fee schedules — a break from the traditional ambiguity of the "donation" model.

The Jodo Shinshu Alternative

Jodo Shinshu is a major Japanese Buddhist tradition that operates on a fundamentally different system. Instead of a kaimyo, the deceased receives a hōmyō (法名) or Dharma Name, prefixed simply with Shaku (釋) for men or Shakuni (釋尼) for women, indicating direct discipleship under Shakyamuni Buddha.

The critical difference: hōmyō names carry no rank hierarchy and no associated rank-based fees. The theological reasoning is that Amida Buddha's salvific grace is unconditional and immediate — there is no need for precept-based rank to earn a better afterlife. This avoids the rank-based fees associated with kaimyo in other traditions; total funeral costs still depend on the temple and services.
