Nikko Chuzenji-ko Onsen Hotel Hana-An

For a trip with your boyfriend, I think Hotel Hanan, located right on the shores of Lake Chuzenji, would be perfect. Their outdoor bath (rotenburo) is a sulfur spring with water drawn from the famous Nikko Yumoto Onsen, and of course, it’s gensen kakenagashi (100% free-flowing from the source). You can gaze out at the stunning views of Lake Chuzenji while you soak, making for an incredibly romantic experience. What’s more, every single room has a lake view, so you can enjoy the beautiful scenery from both the bath and your room. It’s an amazing experience that offers incredible value for the price.

If you appreciate inns with a chic and serene atmosphere, might I suggest Hotel Hanan? It boasts a prime location right in front of Lake Chuzenji, and the interior is impeccably clean with a modern design. The outdoor bath (rotenburo) is a cloudy, free-flowing spring where you can also enjoy that classic, authentic sulfur aroma. One of its main draws—and a rarity in the Nikko area—is that you can experience two different types of hot springs: a sulfur spring and a simple alkaline spring. It's perfect for couples looking to spend some quiet, private time together while indulging in a touch of luxury.

This is a beautiful and relaxing hotel located in Nikko Chuzenji. You can enjoy two types of hot springs (sulfur springs and alkaline springs). When you check in, you will be treated to a specially selected tea. For dinner, you can enjoy a dish featuring colorful vegetables.
