The Takuma Kujira Front Wing 500’s planform, traced from a distributor’s photograph rather than from Takuma’s own.
The Kujira Front Wing has run 6 sizes, 500–1,440 cm², including discontinued sizes, and changes proportion as it grows: aspect ratio runs 5.9 at one end of the range to 8.3 at the other, so its sizes differ in shape as well as in area.
Its 554 mm span is 18% narrower than typical for the area — the median across the 41 current wings within 10% of its size is 678 mm.
No current wing from another brand is within ±5% of area and ±8% of aspect ratio of this one.
None of these is within the tolerances above — each misses on area, on aspect ratio, or on both, by up to 2.4× the tolerance.

The brand's published aspect ratio contradicts its own span and area by more than 10%, so the geometric figure (span² ÷ area) is used instead, and the conflict is noted.
