Japanese yew has mixed fire-resistance evidence: three sources advise against it, one recommends it, and one places it in the middle.
The USDA Forest Service and state Firewise programs rate it “Not Firewise,” the unfavorable end of their four-point scale. Ohio State University Extension assigns high flammability, one band below the top of its five-band scale. Virginia Cooperative Extension also gives it high flammability, the highest class on Virginia’s three-point scale.
Michigan State University Extension reaches the opposite conclusion, identifying Japanese yew as wildfire-resistant and recommended for Michigan’s climate. Kyoritsu Shuppan’s Japanese classification, reproduced by Kagoshima Prefecture, places it in the medium fire-protection-power class. That classification does not put Japanese yew on either side of the disagreement.
The sources use different scales and address different regions. Japanese yew is a low-water tree in the yew family that reaches about 15 feet at maturity. The sound conclusion is limited but clear: calling it fire resistant remains disputed, with more assessments warning against it than recommending it.
Michigan State University Extension Bulletin E2948 is explicitly a list of wildfire-resistant landscape plants for Michigan and includes a Michigan-native field. FireApproved publishes 221 exact GBIF owners from 226 represented source rows and holds 15 complex or non-exact rows. This dated publication scope is not a current site-suitability determination.
Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio site.
Virginia Cooperative Extension's publication opens with Virginia wildfire conditions, identifies its Virginia Firewise Landscaping Task Force, and labels plants native to Virginia. FireApproved publishes 306 exact source owners. Publication scope does not establish parcel suitability or current endorsement of this archived 2009 list.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Native and introduced range evidence
These are exact U.S. botanical-area records from the cited range source. Native and
introduced describe biogeographic relationship, not fire performance or planting approval.
Doubtful and extinct rows stay visible but do not count as current presence.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
Plant hardiness evidence
These values describe the plant source. Your ZIP zone comes from the separate 2023 USDA
Plant Hardiness Zone Map. Whole-zone values stay whole-zone, and a single unresolved value
is not treated as a tolerance range. Different source boundaries stay separate: overlapping
statements are compared independently, while only ranges with no shared zone are called a conflict.
Source prints 5 · single-value meaning unresolved · whole zone precision · source stated

Source location: Cold Hardiness Zone field in the recovered selector record.
Not used for comparison: The recovered selector prints one Cold Hardiness Zone value but does not define it as a minimum threshold or a one-zone range.

Where its sources say to plant it
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
Plant parts are very poisonous. Requires well drained soil.

Table 10-2 prints イチイ in the medium fire-protection-power class. The Kagoshima reproduction says highly fire-protective trees can slow spread, promote upward dispersal of heat and smoke, and intercept flying embers.
