Six people per car, a quick, convenient, and comfortable trip. The cable car to Mt. Omuro was closed due to strong winds, so we couldn't climb the mountain to enjoy the scenery. Luckily, we went to Mt. Komuro instead, where the scenery was quite nice. Strangely, there were no places to eat throughout the trip, so remember to bring your own snacks.
