Overtime Pay in Japan

This page details the conditions and rate for overtime pay in Japan:

Overtime Pay and Article 36

If employees work over 40 hours a week, their employer is expected to pay overtime unless they work in a management position. Companies that regularly assign employees to work overtime should put in place a written agreement between employees and management commonly called “Article 36″ and submit it to the Labor Standards Inspection Office. This agreement is often called  “Article 36″ because it refers to Article 36 of the Japanese Labor Law. This report should be renewed every year.

Holiday (continuing from overnight hours, see example 2 below)Additional 60%

Example of Overtime Payment:

Example 1

The employee’s normal working hours are from 09:00 to 18:00.

The employee worked from 09:00 to 23:00 and so worked overtime from 18:00 to 23:00.

The employee’s additional overtime payment will be calculated in the following manner to account for the additional 4 hours of regular overtime as well as 1 hour of overnight overtime:

(base salary x 1.25 x 4 hours (18:00 – 22:00)) + (base salary x 1.5 x 1 hour (22:00 – 23:00)).


Example 2: (hypothetical)

The employee’s normal working hours are from 09:00 to 18:00.

The employee worked overtime from Friday 9:00 to Saturday 05:00.

The employee’s additional overtime payment will be calculated in the following manner to account for 11 hours of overtime, 4 of which are counted as regular overtime (additional 25%), 2 of which are overnight overtime (additional 50%), and 5 of which are overnight weekend overtime (additional 60%):

(base salary x 1.25 x 4 hours (18:00 – 22:00)) + (base salary x 1.5 x 2 hours (22:00 – 24:00)) + (base salary x 1.6 x 5 hours (0.00 – 05:00))
