Hamamatsu housing and COLA at a glance
Hamamatsu (SH), Japan (DoD locality JP011).
An E-5 with dependents can rent up to $1,247 a month (185,042 JPY) and receives $755 for utilities and maintenance, $2,002 a month in total OHA at the ceiling. With two dependents and 6 years of service, COLA adds about $411 a month. Both are tax-free.
OHA rent ceilings for every grade
OHA reimburses your actual rent up to the ceiling for your grade, so renting below it means a smaller payment, not money kept. Without dependents, the ceiling is 90% of the with-dependents figure.

Rent ceilings effective 16 July 2026. Converted at DTMO's pay-system rate of 1 JPY = $0.006738 (October 1, 2026). DTMO revises it on the 1st and 16th of each month, so the dollar amount moves even when the ceiling does not.
COLA in Hamamatsu
The COLA index here is 114 (effective October 1, 2026), meaning goods and services cost about 14% more than in the U.S. COLA is paid on top of base pay and OHA. Estimated monthly COLA by grade and number of dependents:

Estimates use 2026 base pay at the years of service shown and DTMO's spendable-income table (CY2026 tables (effective Feb 1, 2026)). COLA = spendable income × (index − 100) ÷ 100 ÷ 12. Members without dependents living in government quarters receive a reduced rate. Run your exact grade, years of service and dependents in the OCONUS COLA calculator.
How Hamamatsu compares
The COLA index of 114 is the 2nd-highest of 32 Japan localities DTMO prices for OHA, and in the bottom 23% of the 624 locations worldwide that pay COLA.
Its E-5 rent ceiling ranks 21st of 33 in Japan.
Where the ceiling steps up with rank (with dependents): enlisted $1,146 for E-1 to E-4, $1,247 at E-5 (+$101), $1,283 from E-6 to E-8 (+$36), and $1,497 at E-9 (+$214); officers $1,247 for O-1 to O-2, $1,283 at O-3 (+$36), and $1,497 from O-4 to O-6 (+$214). A promotion that lands before you sign a lease raises what you can rent.
At the ceiling, an E-5 with two dependents draws about $2,413 a month here in OHA and COLA combined, tax-free. The same member receives $2,061 in BAH at the median U.S. housing area. Treat that as a rough guide: OHA pays your actual rent rather than a flat amount, and COLA exists because everyday prices here run higher.
How these rates have moved
The COLA index has moved from 112 (January 1, 2026) to 114 (October 1, 2026). At 2026 pay, that is +$59 a month for an E-5 with two dependents.
| Effective | COLA index | E-5, 2 deps* |
|---|---|---|
| October 1, 2026 | 114 | $411 |
| July 16, 2026 | 108 | $235 |
| April 1, 2026 | 110 | $293 |
| January 1, 2026 | 112 | $352 |
*Monthly COLA at 2026 base pay (6 years of service), so the column isolates the effect of the index.
Exchange rate: DTMO's pay-system rate was 1 JPY = $0.00624 on July 16, 2026 and $0.006738 on October 1, 2026 (+8.0%). The E-5 ceiling of 185,042 JPY is worth $1,247 today against $1,155 then, so the dollar amount on your LES rose by $92 a month without the ceiling itself changing.
