Can foreigners get pension in Korea?

I'm an expat working in South Korea, and I'm wondering if foreigners are eligible to receive pensions here. I've heard that the pension system in Korea is quite comprehensive and beneficial, but I'm not sure if it applies to non-Koreans. Could you please clarify this matter for me? I'd appreciate it if you could provide some detailed information about the requirements and procedures for foreigners to participate in the Korean pension scheme. Thank you!
