Came to Japan earlier this month and quickly bought too much stuff to fit in my carry-on luggage, so I had to upgrade to something bigger. Advice for others facing the same problem; you can ask your hotel to dispose of your luggage for you and then buy a new one, or if you purchase a new luggage from Ginza Karen just bring your old luggage with you and they'll dispose of it for you for free if you buy luggage from them.
