Help: appending string to array value

[dmilan77]

Lets say I have an input array yml as sample.yml

a:
  - candy
  - apple
  - orange

I would like like to modify it by appending a word japan- so that output looks like

a:
  - japan-candy
  - japan-apple
  - japan-orange

I was trying this but all elements get updated with first element.
yq eval '(.a.[] | select(. == "*")) = "japan-"+.a.[]' sample.yml

Use the relative update |= , not at a machine with yq, but it will be something like:

yq eval '(.a.[]) |= "japan-"+.' sample.yml
