We happened to run into a tour group, which completely blocked the entrance. If you buy tickets here, you don't need to exchange them for physical tickets; just tell the staff, and you can go straight in. It's great not having to wait in line, haha. They have two types of mochi and Sakurajima coffee here, which are pretty good; you can give them a try. You can also see Sakurajima in the distance. The garden itself is quite impressive; if I had such a large garden and house, I'd probably get lost at home every day, haha.
