More often than not, when out in Japan you will encounter the traditional squat toilet. Have no fear, they work well. It may seem awkward at first but after a few times you'll feel right at home. I've seen both traditional and modern side by side in larger establishments but in smaller places you have one toilet and this is it. No men's room or ladies room, just one traditional toilet. It is efficient, after you flush the toilet the water from the tank above comes out and you can wash your hands while the water replenishes itself.
