In Japan people usually get a winter break. “How long?” - It depends on the company, though for instance my father had 11 days off in this time, from December 26 until January 5!
People have a long break like this in this summer also, but it’s tough to go back to work after a break. Especially in this season, getting up in every morning is harder than anything as it’s still dark and cold in early morning. And there is a New Year during a winter break, so we eat and drink with family and friends – this is another reason which makes people hard to get back to normal life.
Can you imagine waking up early and going work after the break? – Tough, isn’t it?
