Thank you for your comments. :-) It's so interesting! Most Japanese companies require full-time employees to retire at 60, with an option of a further five years work on reduced pay and terms. I'll spend the greater part of my life with my co-workers. So, building a good relationship at work matters to me more than salary.

This is so interesting! Here in the US it's very common to change jobs, even when you're older. Most people stay in the same type of work, but just want a different job. Sometimes people go back to school to do something completely different (I worked in sales and switched to teaching, and my friend was a teacher but went back to school for coding). This isn't as common, and it would be a lot harder once you reach 30 or so. For teachers, we have pay system of "steps"--you start out on Step 1 and every year you move up a step, earning more. Sometimes, getting a job at a new school will start you over, back to Step 1--so if I worked for 10 years and then changed schools, I would be back to making what a first year teacher makes! So after a few years, it's better to stay where you are). What is the official retirement age for Japan?

Same here, But you should keep in your mind age is just number, You can start a new job or a new life, whenever you want!!
