What Kind of Job Could I Do at 65?

I'm 64, with one year left until 65. I still work full-time in Tokyo, living alone with Niki. After work, I come home tired — and the night routine begins. I want to work a little less after 65. More rest, more time with Niki. But can I live on my pension alone? I started searching for jobs I could do after 65, for 20 hours a week or more. This is a quiet record about retirement, life after retirement, and life after 60. No answers yet. Just a question I leave open. If you feel the same, you are always welcome here. This is Tokyo 60s.
