Base-up ベースアップ

A rise in the whole salary table, separate from the annual step increase. Also written bea, beia, base pay increase.

Japanese pay rises have two parts. The step increase, teiki shokyu, moves an employee one notch up a salary table that already exists, so a 30-year-old earns what last year's 31-year-old earned. A base-up shifts the whole table upward, so every grade pays more than it did. Only a base-up raises the company's total pay bill for a workforce of the same age profile.

For most of the period from the late 1990s to 2022, base-ups were small or zero, and the headline pay rise was little more than the step increase. That changed with inflation. In 2026, Rengo's final spring tally, published in July, put the average rise at 5.01%, the third year in a row above 5%, with the base-up portion around 3.5%. Smaller unions came in lower, at 4.69% overall.

Base-ups are negotiated with the enterprise union in the spring wage talks and usually take effect in April. Companies without a union often follow the published results of their industry.
