Hodosan Roubaien is a specialized garden located near the summit of Mt. Hodosan (497m) in Nagatoro, Saitama Prefecture. The garden covers approximately 15,000 square meters and is home to about 800 plants, totaling roughly 3,000 Winter Sweet (Roubai) bushes. Known in English as "Winter Sweet," these plants are incredibly hardy and release a deep, sweet fragrance from winter through early spring. It is considered one of the most beautiful locations in the Kanto region, offering a sensory experience where the scent of the flowers meets a stunning view of the Chichibu Basin and surrounding mountains.
Mt. Hodosan has long been a beloved mountain for locals, and the area near the summit has been developed into specialized gardens to enjoy seasonal flowers. The Winter Sweet plays a central role here, symbolizing the transition of seasons by blooming amidst the winter cold. The garden features three distinct varieties of Roubai, each offering unique shapes and scents, contributing to the rich botanical heritage of the area.

The garden features three main varieties of Winter Sweet: "Wa-Roubai," a small variety with a reddish-purple center; "Soshin," which has a strong fragrance and sword-shaped petals; and "Mangetsu." These varieties bloom together in the open, airy space at 497m altitude. Another major highlight is the panoramic view from the summit, which allows visitors to gaze upon the iconic Mt. Buko, the serrated peaks of Mt. Ryogami, and the sprawling cityscape of the Chichibu Basin.
The peak blooming season is typically from late December to late February. During this time, the intense fragrance and bright yellow flowers stand out beautifully against the sparse winter landscape. The flowers appear particularly vibrant under the soft sunlight of early spring. Since blooming conditions can vary depending on the weather, it is common to check the latest flowering status before visiting.

The area is perfect for nature walks and hiking. You can enjoy a scenic journey to the summit via the ropeway, which provides a wonderful view of the Chichibu region during the ascent. The surrounding area also features the Hodosan Small Animal Park and the Umekahana Garden, making it an ideal spot for a full day of nature-themed exploration.
