E75 Bra Size, In Full

A Japanese E75 is a 75 cm band with a E cup: written cup-first, measured in 2.5 cm steps, and one letter ahead of the Western alphabet. In US terms this body wears a 34D.

NotationCup first: E75, not 75E

The trap

A Japanese E is not a Western E

Japanese cup labels start earlier and step in 2.5 cm increments, so each letter sits roughly one label ahead of its Western namesake: this E75 corresponds to a US 34D and EU 75D. Order your Japanese letter from a Western shop (or vice versa) and you’re a full cup off before the parcel ships. The converter translates in both directions.

Bands translate cleanly (same centimeters as EU labels); only the letters shift.

Japanese sisters move in 5 cm band steps with one cup letter, same volume, different circumference. Useful when domestic stock stops one band short of yours.

Construction

What works at this size

This volume rewards structure, which mainstream Japanese ranges provide less of: domestic stock thins out fast above an E70/E75 frame. Seamed cups and firm bands do the work; many shoppers at this size mix domestic and international brands via conversion.

What is Japanese E75 in US sizing?

US 34D (UK 34D). Japanese cup letters sit one label ahead of Western ones for the same body (a Japanese E corresponds to a Western D-tier cup) so carrying the letter across unconverted buys a cup too big.

What measurements is E75 for?

An underbust around 75 cm (roughly 72.5–77.5 cm) and a top bust near 95 cm: a difference of about 20 cm, which Japanese sizing labels E. Japan measures in 2.5 cm cup steps against Europe's 2 cm, so conversions are nearest-label, not exact.

Why is the cup letter written first in E75?

Japanese convention writes cup-then-band. C70, not 70C. Same information, reversed order; on tags in Japan you may also see the band alone (70) with the cup on a separate line.
