Revenue is generated through prepaid mutual aid subscriptions, per-event wedding and funeral service fees, hotel and restaurant transactions, eldercare fees, and Buddhist altar/tombstone sales. The go-to-market is direct-to-consumer through owned venues and regional branch offices in cities including Shimonoseki, Tokyo, Akita, Morioka, Sasebo, Fukuyama, Iwakuni, Hofu, and Kitakyushu. The Miraiyel subscription model is the structural anchor of the business, generating approximately ¥1.36 trillion in pre-collected member funds (前受金残高) on the balance sheet as of January 2026 against disclosed group revenue of ¥77.7 billion for the same fiscal period.
