JP bra sizes
JP bra sizes use a band label from 60 to 140 and a cup letter; the band number matches the EU label, while US and UK band labels pair as shown in the chart.
JP bands, 28 to 60

JP band labels run from 60 to 140 in steps of 5, matching EU band labels. For comparison, US and UK band 28 pairs with JP 60, and each listed US and UK band pairs with the JP label shown in the chart. A band label identifies the tag, not a body measurement; body ranges come from the underbust method or add-4 method.
JP cup letters run in order from C through D, E, F, G, H, I, J and K. They start at C for a difference of 2 in and end at K for 10 in. At each listed difference, the JP letter is one alphabet place later than the EU letter. A published rule counts cups in centimetres, with A at a difference of 10 cm and a new letter every 2.5 cm; those centimetre steps cannot be turned into inch rows without choosing a band.
Published charts disagree in how they set out JP cup letters: one rule uses centimetre differences, while the label chart lists inch differences. Letters also vary by brand. The chart lists no letters at differences of 0 and 1 in, where it says to check the brand, or above 10 in. Examples of JP labels are 75C, 80D and 85E.
