Storage company in Denmark

Can someone on this site recommend a good storage company in Denmark? I am in Bording but can go to Herning or another bigger city if that helps. I am going to be moving to Tokyo for nine months for a work project so only need to store my stuff temporarily. I considered shipping it to Japan with me, but it doesn't seem to make sense if the project over there is not even a year long and then I will be back here in Denmark. Also, my company is not going to pay for that so I need to watch how much money this whole venture is going to cost because it is coming directly out of my pocket. I am in a small two bedroom flat so I don;t think I will need to much space to store my belongings. If you could let me know the available sizes of the storage units, that would be best. That way I have a few choices of which size to go with for my things.
