If you have read the English material on Six-Star Astrology for any length of time, you have probably encountered the phrase "kill year" used several different ways. Sometimes it means a three-year window. Sometimes it means one year. Sometimes it means the middle of a cycle, sometimes the end. The terminology is genuinely confused, and the confusion is not your fault — it is a translation problem that has compounded across two decades of fan blogs, machine-translated subtitles, and increasingly the Netflix dramatization of Kazuko Hosoki's career, which uses "kill year" loosely in English subtitles for at least three different Japanese terms.

The original system is more precise than the English coverage suggests. There are not one but four distinct caution markers in the twelve-year cycle, with different scopes, different intensities, and different prescriptions. This article disentangles them.

The original terms

Hosoki's system, written in Japanese, uses four separate words for cautious years. They overlap in the character 殺 (satsu, "kill" or "sever"), which is what creates the English confusion. But they refer to different things.

• 大殺界 (daisakkai) — the three-year stretch: Shadow + Halt + Decline (phases 10, 11, 12). The main event of the cycle.
• 大注殺 (daichūsatsu) — a single warning year, typically appearing in Confusion (phase 6). Functionally an overextension alert.
• 小殺界 (shōsakkai) — a label applied to the Weakness year (phase 4). A minor warning year, sometimes called the "small kill year."
• 中殺界 (chūsakkai) — a label applied to the Confusion year (phase 6). A minor warning year in the middle of the cycle, sometimes called the "middle kill year."

The pronunciation distinctions matter for translation. Daisakkai (大殺界) and daichūsatsu (大注殺) sound similar in romaji and share characters, but they are different concepts. Shōsakkai and chūsakkai are paired diminutives of daisakkai — same structural word, different scale.

Why English sources collapse them

The collapse happens in three steps.

Step one: literal translation. All four terms contain 殺, which most translators render as "kill." That gives "great kill realm" (daisakkai), "great injection kill" (daichūsatsu), "small kill realm" (shōsakkai), "middle kill realm" (chūsakkai). The English already sounds awkward.

Step two: shortening. Translators trying to avoid four awkward phrases shorten everything to "kill year" or "kill period." Different translators pick different concepts to assign the phrase to. By the time the term reaches a fan blog, "kill year" can mean any of the four.

Step three: pop culture. Netflix subtitles for Straight to Hell / 地獄占星師 use "kill year" as a free-floating dramatic phrase that the English script needs in roughly the same places the Japanese script uses any of the four terms. The subtitle translators are not trying to disambiguate — they are trying to keep the dialogue moving.

The result: an English reader sees the phrase "kill year" used to mean a one-year event, a three-year event, the middle of the cycle, and the end of the cycle, sometimes within the same article. The information is genuinely garbled.

At-a-glance comparison

The right column shows the most common English renderings. Note that there is no settled convention — different writers handle these differently, which is part of the problem.

What each one actually means

Daisakkai (大殺界)

The big one. Three calendar years in a row, always Shadow → Halt → Decline. Every Six-Star type passes through Daisakkai once per twelve-year cycle. The classical caution list — do not marry, do not start a business, do not move, do not sign large contracts, do not have elective surgery — is pointed at this period, especially at the Halt year in the middle.

This is the term that pop culture mostly means when it says "kill year," even though Daisakkai is three years long and "kill year" implies one. If you see "the kill year" in an English article about Six-Star Astrology, default to assuming the writer means Daisakkai unless context says otherwise.

The full background on Daisakkai is in the explainer article. The practical playbook for surviving it is the how-to-survive guide.

Daichu-satsu (大注殺)

A single warning year, separate from the three-year Daisakkai. The traditional usage is that daichūsatsu refers to a year of overextension risk — a year when the cycle's energy is still available but the cycle is warning that decisions made in this year tend to commit you to more than you can sustain. Most commentators place daichūsatsu in the Confusion year (phase 6), although there is some variation across schools.

The character 注 (chū) means "pour" or "focus" — the term reads as "the kill of pouring too much in." That is the functional warning: do not pour too much into this year's decisions.

Daichu-satsu is the term most often mistranslated as "kill year" in fan materials that are trying to describe a single difficult year. If you encounter a Hosoki-adjacent source describing a one-year window, daichūsatsu is what it probably means, not daisakkai.

Shōsakkai (小殺界) — the small kill year

The label applied to the Weakness year (phase 4), the fourth year of the twelve-year cycle. Sometimes also written as the "small calamity" or "small kill year." This is a single warning year that appears about a third of the way into the cycle.

The practical reading is much gentler than Daisakkai. Shōsakkai is a year of low physical energy and slightly impaired judgment — not catastrophic, just a phase to be aware of. The classical advice is: watch your health, avoid overextending, do not make permanent decisions while tired. None of the heavy don'ts of Daisakkai apply at shōsakkai intensity.

Crucially, shōsakkai is not part of Daisakkai. It is a separate, smaller warning. Many English fan materials lump them together because both contain 殺. The original system keeps them very separate.

Chūsakkai (中殺界) — the middle kill year

The label applied to the Confusion year (phase 6), the sixth year of the cycle. Same structure as shōsakkai — a single warning year, not a Daisakkai year, but a phase to be aware of.

Chūsakkai often overlaps in usage with daichūsatsu, because both fall around the cycle's midpoint and both describe a kind of mid-cycle warning. Some practitioners distinguish them (chūsakkai for the calendar phase, daichūsatsu for the overextension dynamic). Others use them somewhat interchangeably. The English material, predictably, just calls all of them "kill year."

The practical reading: Confusion is a phase where decisions made under stress are the most regretted. The Hosoki advice is to sleep on things, especially expensive things. Again, much lighter than Daisakkai.

Why the distinction matters

If you only read the English coverage, you can end up with the impression that Six-Star Astrology fills the cycle with bad years — a kill year here, a kill year there, the great kill realm at the end. That impression is wrong, and it is one of the reasons people abandon the system thinking it predicts only misfortune.

The actual distribution is more spread out. Out of every twelve years:

• 9 phases are non-warning years — Seed, Sprout, Bloom, Achievement, Reunion, Prosperity, Stability, plus the implicit normalcy of the cycle's main rhythm.
• 2 phases are minor warning years — shōsakkai (Weakness) and chūsakkai (Confusion). Single years, gentle advice, no major don'ts.
• 3 phases are Daisakkai — Shadow, Halt, Decline. Single block of three, heavy don'ts, real planning required.

That is two single warning years and one three-year warning block, for a total of five cautious phases out of twelve. Different scales, different prescriptions. Reading them all as "kill years" makes the cycle look more punishing than it is.

It also matters when planning. If a fan source tells you your "kill year" is 2026 and you treat it like Daisakkai when it is actually shōsakkai or chūsakkai, you will overcorrect — you will postpone a wedding that did not need postponing, refuse a job change that the cycle would have permitted, or buy into a fear narrative the system does not endorse for single warning years. The classical don'ts belong to Daisakkai. They do not apply at the same intensity to the smaller warning years.

A practical heuristic

When you encounter the phrase "kill year" in any English Hosoki material, ask three questions before believing the framing.

1. How long is the window? One year or three? If three, you are reading about Daisakkai. If one, you are reading about something else.
2. Where in the cycle does it fall? If at the end (phases 10–12), Daisakkai. If at phase 4, shōsakkai. If at phase 6, chūsakkai or daichūsatsu. The position locates the concept.
3. What advice is the source giving? If the source is telling you not to marry, not to start a business, not to move — that is Daisakkai-tier advice. If the source is telling you to be a little careful and rest more — that is shōsakkai or chūsakkai-tier.

The Japanese-language Hosoki literature is much more careful about these distinctions than the English fan material. If you want to go deeper than English coverage allows, the primary sources to look for are Hosoki Kazuko's 1980s books and Hosoki Kaori's recent essays, which use the four terms consistently and precisely.

The short version: there is no single "kill year" in Six-Star Astrology. There is one three-year block (Daisakkai) that the cycle treats as structurally important, two single warning years (shōsakkai and chūsakkai) that the cycle treats as minor cautions, and one overextension marker (daichūsatsu) that the cycle treats as a tactical alert. Conflating them is the most common English misreading. Holding them apart is the first step to using the system the way it was designed.
