Excuse me, are roses and roses the same plant? In Japanese, rose and rose have the same pronunciation, so are they the same plant?

No. They belong to Rosaceae, but they are different species. We usually see that the roses sold by flower shops are actually Chinese roses, not real roses. Its flowers are bigger than roses, mainly with double petals. Rose branches are longer and softer, while rose branches are shorter and thicker. Real roses are mostly pink in color and have single petals, which are easy to distinguish from the other two (note: the picture is a real rose).
