Visiting these locations in Japan's far east during the summer was a wonderful experience. The weather was comfortable, and you didn't have to worry about getting lost or missing out on the beautiful scenery from your car. The most memorable part of the trip was the Nozue Peninsula. Although there was a section of wooden boardwalk over the sea that was only wide enough for one person and had no handrails, making it a bit dizzying and thrilling, the magnificent sea view was absolutely worth it. The only downside was that the all-Japanese tour guide's explanations were completely incomprehensible, so it's essential to plan your itinerary carefully beforehand. Also, the three nights' onsen hotels were quite old (although they used to be high-end hotels, they hadn't been renovated), which was a minor regret of the trip. Overall, however, it was still a fantastic trip! 👍
