On leaving a job, employees are supposed to be given a "Rishoku-hyo" document showing their ID number (the same number is supposed to be used by later employers), employment periods, and pay (which contributions are linked to). The reason for leaving is also documented separately. These items affect eligibility, timing, and amount of benefits. The length of time that unemployed workers can receive benefits depends on the age of the employee, and how long they have been employed and paying in.
