Hello all. I have just bought a bike box (http://www.wiggle.co.uk/roof-box-touring-box-bike-box/) for my upcoming holiday in march. It is larger than I expected to the degree that I worry that it is too big to take on the shinkansen. I had thought I could store it at the end of the carriage but I dont want to inconvenience other passengers. Does anyone have any experience of travelling with a bike or other large luggage on the shinkansen. I have thought about putting the bike in a rinko bukuro but dont have anywhere to store the box. The box is too big to use takkyubin services. I will have to leave my bike at home unless I can find a solution to this.
