Executive Summary: Revelation Japanese Language Package

Why it matters

Revelation extends a mature, doctrinally sound Japanese Bible-translation tradition (Shinkaiyaku 2017) into the highest-stakes theological territory in the whole Language Package family: final judgment, a renewed cosmos, and exclusive worship of the Lamb — presented to a largely secular, biblically illiterate Japanese audience with light but genuinely competing Shinto/Buddhist cultural furniture already in place (jigoku hell-realms, kami spirits, benevolent dragons, ancestor-memorial ritual, funeral-white symbolism). Getting this package right determines whether learners receive the text’s actual claims of final, non-cyclical victory and grace, or unconsciously reprocess them through Japan’s cyclical, appeasement-based, or non-exclusive religious defaults.

Key findings

• 34 granular doctrines were derived from the curriculum’s 9 top-level doctrines; 9 are Critical risk and 15 are High risk — 24 of 34 (71%) require mandatory human theologian review, versus 8 Medium (native speaker review) and 2 Low (automated review only).
• ~90 terms are tracked in the Revelation term registry; 16 are Critical risk and 31 are High risk — 47 of ~90 (roughly half) require mandatory theologian-level scrutiny at every occurrence, a substantially higher concentration than the Romans baseline.
• The core passage (Revelation 21:1-8) alone contains at least six Critical/High-risk terms in eight verses (新しい天と新しい地, 海, 花嫁, 幕屋/共に住む, 価なしに, 火の池/第二の死, 恐れる者), the single highest term-density-per-verse cluster in either curriculum.
• Two entirely new forbidden-substitution risks not present in Romans were identified: 七つの霊 (Seven Spirits) vs. 御霊 (Shinto enshrined-spirit vocabulary) and 火の池/第二の死 (Lake of Fire/Second Death) vs. jigoku/Enma (cyclical, karma-resolving Buddhist hell-realm cosmology) — both now Critical-tier forbidden-substitution rules.
• Japan’s own religious landscape supplies two genuine positive teaching bridges not available to the same degree in Romans: the Kirishitan martyr history (26 Martyrs of Nagasaki, 1597) for 証し／証人／殉教者, and Japan’s established full-inheritance heir-adoption practice (養子縁組) reinforcing 21:7’s inheritance promise.

Risks

• New Heaven and New Earth (新しい天と新しい地) is the single highest-stakes term in the entire curriculum: 新しい alone cannot distinguish “renewed, continuous creation” from “unrelated replacement,” and sits directly beside the competing, genuinely close Pure Land Buddhist 極楽 (Gokuraku) rebirth-paradise structure.
• “No more sea” (21:1) carries unique pastoral risk for this destination language alone among the package family: Japan’s sea-deity religious heritage, fishing-village economic identity, and living 2011 Tōhoku tsunami memory make a literal misreading not merely confusing but potentially insensitive.
• Worship exclusivity (礼拝する／仕える) collides with Japan’s dominant “worship many, exclude none” shrine-and-temple cultural default — the sharpest cross-tradition collision point identified in the comparative theology analysis for this doctrine.
• Imperial-institution resonance (御座／大きな白い御座 vs. 高御座, the actual proper name of the Japanese Imperial Throne; 神の国 vs. pre-1945 State Shinto’s 神国日本 slogan, intensified at Revelation 11:15’s triumphant political-sounding language) recurs at higher doctrinal density than in Romans.
• Valence-flip risk: white robes (白い衣) register culturally as funeral/mourning dress in Japan, the reverse of the intended purity/victory/joy sense — a silent translation without explicit reversal-teaching risks landing as the opposite emotional register from what the text intends.

Opportunities

• Japan’s Kirishitan martyr history gives the Perseverance and Martyrdom doctrines a genuine, respectful cultural anchor point not equally available elsewhere in this package family.
• The baseline’s already-established on-giri/grace fencing (from Romans 3-4, 11:5-6) extends cleanly and powerfully to Revelation’s climactic 価なしに (freely, no cost) at 21:6 and 22:17 — the same teaching apparatus simply needs to be redeployed at the book’s most emotionally weighted invitation and closing benediction.
• Japan’s adult-heir adoption tradition (養子縁組) continues to function as a positive bridge for 21:7’s inheritance promise, exactly as it did for Romans 8.
• The curriculum’s own Symbolic and Apocalyptic Interpretation doctrine gives curriculum writers a built-in occasion to pre-empt Japan’s kaijū/tokusatsu monster-movie and number-superstition reading habits explicitly and early, rather than fighting them term-by-term throughout the book.

Recommended actions

1. Load translation_memory.json, bible_term_registry.json, doctrine_risk_registry.json, and 12_ai_translation_requirements.md (this Revelation extension) together with the Romans baseline before any Phase 2 segment translation begins.
2. Route all 24 Critical/High-risk doctrines and all 47 Critical/High-risk terms through mandatory human theologian review; do not permit automated-only approval for any of these, consistent with the escalation rules in Step 10.
3. Treat Revelation 21:1-8 as a combined-verse review unit in addition to term-by-term validation, given its unmatched density of stacked Critical/High risks (see 21:6 and 21:8 in particular).
4. Require first-occurrence explanatory/fencing clauses (per Section 2B of the Linguistic Gap Analysis) to be re-supplied at the start of every lesson document, not merely once across the whole curriculum, given Revelation’s episodic structure and the likelihood that learners enter study at non-sequential chapters.
5. Brief all reviewers on the two newly identified absolute-forbidden substitutions (御霊 for Seven Spirits; unfenced 地獄-style framing for Lake of Fire/Second Death) as Critical-tier equivalents to the Romans baseline’s existing 解脱/化身/権化/現人神 forbidden list.
