Wenger coached Nagoya Grampus Eight before moving to the Gunners.
He told arsenal.com: 'What stands out for me is, for such a short period of experience, the quality of the organisation in the league. I moved there in 95 and it was created in 93. For only the third year, the quality of the organisation was something that stood out to me.
"Secondly the huge, unbelievable desire and hunger for training from the Japanese player. When I arrived in the morning they were already on the pitch and training started one and a half hours later. I had to hide the balls before training and say to the kit man don't give them to the players because when training started they were already tired because they had practised so much on the pitch!
"The third thing that was very interesting for me was that, when I arrived, you could not draw. You could only win or lose so each game was decided on penalties after extra time. You could never get away with a draw if you had a bad patch!
"Another thing that was interesting is that to promote football you played 20 per cent of your home games in a neutral city. That was quite amazing and interesting. It was a home game but it could be 200 miles away from your city just to make an advertisement for professional football, just to show what it is. They pushed that through and it was very interesting."
