How about getting your grandma tickets to a taiko drumming performance or a workshop? Not only will she be able to enjoy the performance or learn new drumming skills, but she may also get the chance to meet other people who share her love of taiko drumming. Additionally, you could also get her a taiko drumming CD or book on the history and culture of taiko drumming. A nice pair of drumsticks or a traditional Japanese drum (if she doesn't already have one) could be a great way to help her feel more connected to the art form as well.
Or you can get her a star map with an important date you share.
