You can apply yourself directly to the Japan Pension System, or if you are in a country that has a Pension Totalization Agreement, then in many cases you can apply through the Pension Office of the Country of Residence, and they will arrange all the paperwork with the Japan Pension System for you.
Depending on the Tax Treaty between Japan and the Country of Residence, you may be able to receive the Pension Payments free of withholding tax in Japan. Some countries' Tax treaties allow Tax Free payment from Japan, and others don't. In pretty much all cases the Pension Income will be taxable in the country of residence.
The normal date to start receiving Japanese Pension Benefits is currently 65 based on all contributions to that time.
You can elect to start receiving a reduced Pension from age 60 onwards, based on all contributions to that time. The Reduction is shown here:
Rate = 100% - Discount Rate % shown. e.g. Age 60 would be 100% - 30% = 70% of projected Age 65 Benefit based on all contributions to Age 60

You could also delay and receive an increased Pension past age 65, based on all contributions to that time. The Increase is shown here:
Rate = 100% + Increase Rate % shown. Age 70 would be 100% + 42% = 142% of projected Age 65 Benefit based on all contributions to that time.

In any case the Benefit is based on the number and amount of contributions to the Basic and/or Employee Pension Systems.
It will differ by person, but you can expect a partial pension of about No.of Actual Months Contributions / 480 of a full pension...
You might want to get a Projection from the Pension Office of how much you would expect at age 65 at today's benefit rates based on your Contributions until the time when you leave, before you leave Japan. The Benefit rate will then raise annually by the roughly the rate of Japanese Inflation until you decide to start receiving from 70% of that at age 60, to 100% at age 65, to 142% at age 70 or max 184% of that value at age 75...
