Our tour guide, Matt Yan, arranged the itinerary well and was a very nice and enthusiastic person. If you want to visit many classic attractions, this is truly a satisfying experience. I thought it was great, but unfortunately the weather was bad; Owakudani was completely shrouded in fog. 😆 I'll definitely come back again next time! 👍
