How about a beautiful shogi board set for your grandma? You can find a good quality shogi board set online or at a local game store. You can also personalize it by engraving your grandma's name on the board. Additionally, you could also look into getting some new shogi pieces or a book on shogi tactics to go with the board set. Another idea could be to take her out to a shogi tournament or invite her to a shogi night with some of her friends who also enjoy the game.
Or you can get her a star map with an important date you share.
