Before arriving in Nagoya, I checked the weather forecast, and it predicted rain every day. Fortunately, during my three-day tour, only the day in Kamikochi was it pouring rain; the other two days were incredibly enjoyable. We stayed at a hot spring hotel for two nights, with breakfast and dinner included, so we didn't have to worry about anything. One day, Lion Travel even thoughtfully provided each person with a large portion of sushi rice balls for lunch. Our guide, Ogawa, was attentive throughout the trip, knowledgeable, and shared historical anecdotes on the bus, making the short drive pass by effortlessly. He was truly professional and deserves praise.
