Can I retire in Korea?

Good day, I'm considering retiring in Korea. Could you please provide some insights on this matter? I'm particularly interested in the financial and lifestyle aspects of retiring in Korea. For instance, what are the tax implications for foreigners retiring in Korea? Are there any special retirement plans or schemes available for foreigners? Also, what are the costs of living like in Korea, especially in comparison to other countries? Lastly, are there any cultural or social barriers that I should be aware of before making this decision? Thank you for your time and assistance.
