Hilarious images have emerged online capturing legless Japanese businessmen who overdid it at after-work drinks parties.

Pictures show the suited workers slumped over on seats, sprawled out on their backs in the street and sitting on train platforms next to their briefcases having had one too many after a hard day's work.

The images highlight the notorious post-work drinking culture in the country where some staff are given allowances to ensure they join in with work-based boozing sessions.

It is not a new phenomenon, and management consultant Shinsuke Suzuki told Japan Today in 2014 and said: 'To a large extent, if you’re not an employee with a specialised technical skill, then there’s nothing to really distinguish you from the other workers.

'So if you want to stand out and get promoted, attending drinking parties and building up an in-house network is much more effective than simply working your heart out at work.'

And although the businessmen are encouraged to go for a tipple after work, it's safe to say that these probably overdid it slightly.

The view of the expert chimes with many in the country, with one website user writing below the pictures: 'In Japan, it's a culture.

'If you are married and you go home early, you wife will worry.

'Your wife will scold you; "Why you did not entertain your boss?".

'If you come home later, or even wasted, your wife will know that you have done whatever it takes on your job.'
