traveling for my grandmother’s birthday

November 10 is my grandmother’s birthday. My grandmother will turn 77 years old on this birthday. It is said as becoming kiju in Japan. It is a custom that congratulating the relative of 77 years. So my family and I are planning to perform her birthday party. We are going to take her to hot spring and Akiyoshidai. Akiyoshidai is the biggest limestone cave in Japan. I love my grandmother, so I want her to please. I hope this travel will become happy birthday for her.
