You might try contacting Best Hikkoshi. They are a smaller company and I had no problem booking with them only a couple of weeks in advance. They were also pretty cheap! http://www.bestservice.co.jp/ Moving on a Friday afternoon is 30 to 40% cheaper than moving on a Saturday morning, so that is what I did. It was the 2nd time I used them and have been satisfied both times.
Good luck Taro!!!!!!!!
