It looks great to wear Japanese traditional wear 'kimono' and visit shrine and temple, walk around old town in Kyoto. It's easy to rent a kimono because there are many rental kimono shops around popular places in Kyoto. It take about a hour to change from your casual wear to kimono and costs about ¥3000-¥4000 per parson. You will be able to rent it cheaper if you are couple or group. They have many rental plans, so you can choose good one for you. I recommend you to book before just incase. Enjoy feeling Japanese culture!!
