> japanese society and businesses don’t reward people that jump from job to job.

I can see why this is good and bad, but honestly, I wish more places in the West were like this too. I've had the same job for 7 years as a programmer, and it baffles me how many people find that surprising/unusual.

I seriously rather not look for another job, but I due to some upcoming changes at my work, I think I may have to.
