Wikipedia does not have a clean English page for the word. Search engines route you to fan blogs, magazine sidebars, and increasingly to translated subtitles from the Netflix dramatization of Kazuko Hosoki's career. None of them quite explain the term. This article is the page that should exist.
The word Daisakkai (大殺界, daisakkai) is the name for a three-year window in the Six-Star Astrology cycle. Every person passes through it once every twelve years. The exact calendar years differ by star type, but the structural fact is the same for everyone: nine years of building, then three years labeled as a time to be careful. This article explains what the word means, where it comes from, why those three years, and which English translations to trust.
What the word literally says
The kanji decomposes cleanly.
- 大 (dai) — great, large
- 殺 (satsu / sakkai in this compound) — kill, slaughter, sever
- 界 (kai) — realm, world, boundary
Strung together, 大殺界 reads almost too literally as "the great kill realm." The character 殺 is the one that carries the dramatic load, and there is no softening it. It is the same kanji used in 自殺 (suicide), 殺人 (homicide), 暗殺 (assassination). The author of the term, Kazuko Hosoki (細木数子), chose strong language on purpose.
The pronunciation in Japanese is "die-sa-kai" — four syllables, with the middle pair shortened into a small geminate. English speakers most often write it daisakkai (one k) or daisakai (no double letter). Both are accepted. The Hosoki office's official romanization in trademark filings has historically been Daisakkai, and that is the spelling that has stuck on the English internet.
Where the term comes from
Daisakkai is a coined term, not a classical one. It does not appear in pre-modern Japanese fortune-telling literature. It was invented along with the rest of the Six-Star Astrology (六星占術, rokusei senjutsu) system in 1980, when Kazuko Hosoki published the first volume of 六星占術によるあなたの運命 (Your Destiny by Six-Star Astrology). The book went on to sell into the tens of millions of copies across its multi-decade run. The Daisakkai concept did most of the marketing.
The term has the rhetorical structure of a coined religious word: a familiar character (大) elevated by a strong second character (殺) and grounded by an abstract third (界). The same structural trick produces 結界 ("warding boundary"), 仏界 ("Buddha realm"), and similar compounds in Japanese mystical vocabulary. Hosoki's training was eclectic — she drew from Chinese metaphysics, Buddhist cosmology, and her own clientele's intuitions — and the word feels old on purpose. It is not.
If you want the deeper biographical context, the Kazuko Hosoki entry covers her life and her relationship to the system.
Where it sits in the twelve-year cycle
Six-Star Astrology divides life into a repeating twelve-year cycle. Each year of the cycle has a phase name:
- Seed (種子)
- Sprout (緑生)
- Bloom (立花)
- Weakness (健弱) — also known as the "small kill year" (小殺界)
- Achievement (達成)
- Confusion (乱気) — also called the "middle kill year" (中殺界)
- Reunion (再会)
- Prosperity (財成)
- Stability (安定)
- Shadow (陰影) — Daisakkai begins
- Halt (停止) — the deepest of the three
- Decline (減退) — the closing year
The Daisakkai is phases 10, 11, and 12 — Shadow, Halt, and Decline. Always those three, in that order, three calendar years in a row. After Decline the cycle wraps back to Seed and begins again.
The internal logic of the system is biological. The first three years (Seed through Bloom) are about emergence. The middle six (Weakness through Stability) are about development. The last three (Shadow, Halt, Decline) are about closure. You cannot have a cycle without a closing. The Daisakkai is where Six-Star Astrology does its closing work — the composting of the previous twelve years so that the next one can begin from clean ground.

Why three years, not one
Western astrology has a similar low-point concept — the Saturn return, which lasts roughly two to three years as Saturn orbits back to its natal position. The Chinese system has 本命年 (běnmìngnián, "zodiac year"), but that is a single year. Six-Star Astrology lands in between: three years, structured as a sequence rather than a single event.
The three-year length is doing real work. A single bad year can be ridden out. A three-year stretch forces a different kind of behavior — slower, more conservative, oriented toward closure rather than wait-it-out. The system's prescriptive advice (don't start large new commitments, finish open loops, conserve energy) only makes sense at the three-year scale. It would be silly advice for a one-year window.
The three phases are also internally distinct. Shadow is the warning year — energy starts to thin, but the world has not yet noticed. Halt is the deepest point, where the system advises against major decisions of any kind. Decline is the recovery and release year — the cycle's exit. Each year asks for different work. Treating all three identically is the most common misreading.
Daisakkai versus daichu-satsu
The most frequent point of confusion. The Six-Star cycle has three kinds of cautious year, not one:
- Daichu-satsu (大注殺, daichūsatsu) — a single warning year that appears mid-cycle. Functionally a one-year alert about overextension. Often confused with Daisakkai because of the overlapping 殺 character.
- Shōsakkai / Chūsakkai (小殺界, 中殺界) — labels sometimes applied to the Weakness year (phase 4) and the Confusion year (phase 6). They are minor warning years. Not part of the Daisakkai itself, even though they share the 殺 root.
- Daisakkai (大殺界) — the three-year stretch (Shadow + Halt + Decline) at the end of the cycle. The main event.
If you see "daichu-satsu" referenced in an English source describing a single difficult year, that is a different concept. The two words overlap in vocabulary but not in scope. Six-Star Astrology cares about both, but only Daisakkai gets the three-year structural emphasis.
English translations and which ones to use
There is no settled English word for Daisakkai. Different translators have made different choices, and they each carry slightly different connotations:
- Great Calamity Period — the most common English rendering. Used in fan translations, in Netflix subtitles for Straight to Hell / 地獄占星師, and in most consumer-facing English materials. Captures the original drama. Sometimes feels too apocalyptic.
- Kill Year / Kill Period — closer to the literal meaning of 殺, but reads as horror-movie copy in English. Rarely used in serious writing.
- Void Period — a softening borrowed loosely from Buddhist vocabulary. Loses the warning edge.
- Stagnation Cycle — the calmest option. Accurate to the modern reframe (the work of these years is internal, not external), but loses the historical force of the original term.
- Daisakkai (untranslated) — increasingly common as the system gains English readers. Treats the word the way karma or feng shui are treated: a borrowed term with its own meaning that does not need translating.
Our own product copy uses Daisakkai and Great Calamity Period interchangeably, with a preference for Daisakkai in headings and the longer English phrase in body text. The full reasoning for that choice is in the Great Calamity Period article.
What it is not
Three claims that get applied to Daisakkai that the actual system does not support.
It is not a curse. The system is calendar-based, not karma-based. Everyone gets the same three years per twelve. No ritual cancels them, no good behavior shortens them, no bad behavior triggers a fourth.
It does not predict disaster. The traditional readings advise caution, not catastrophe. People who plan well frequently look back on their Daisakkai years as quiet, productive, even pleasant. The bad outcomes are concentrated among people who ignored the cycle and started major new commitments they could not exit.
It is not unique to Hosoki's system. Most of the major Asian fortune-telling traditions have a low-point window of some kind. Daisakkai is Hosoki's specific framing of that universal pattern. The pattern itself — extended periods of consolidation between periods of growth — predates her and exists outside her system.

For the deeper cultural context on how the modern Hosoki office, in particular Kazuko's daughter Hosoki Kaori, has been quietly reframing the Daisakkai away from doom-language and toward a more useful planning framework, the family legacy article covers that shift.
The short version of everything above: Daisakkai is a coined Japanese term for a three-year structural low point in a twelve-year astrological cycle. Hosoki invented it in 1980. It is dramatic on purpose. It is also, in practice, less scary than the name suggests.
