I'm sure you have all these markers laying around with no where to put them. Your white board is probably in a completely separated place as well. Why don't you bring the two together? For only ¥100 you can purchase a marker holder that attaches to your white board. It comes in two forms, magnetic and sticky. Most white boards now come with some sort of metal backing to allow for magnets, so there is nothing to worry about! It's so easy, and it'll make your life easier too!
