Every late April to mid-May. No exact date range as the flowering status is unpredictable yearly. Make sure to check the hotel's daily schedule before visiting.
Odakyu Hotel de Yama is located along the shores of the picturesque Lake Ashi, and has been operating for almost eight decades— it sits on the historic grounds of the villa once owned by Baron Koyata Iwasaki, the fourth head of Mitsubishi. The gardens, which have been carefully preserved since the Baron’s time, feature rare azalea varieties dating back to the Edo period, along with historical rhododendron species such as the Gomer-Waterer (the first Western rhododendron introduced to Japan).
To celebrate all this floral beauty, the hotel will be hosting their Azalea and Rhododendron Fair from late April to late May. Please note that specific dates are not mentioned on the official event page, they only provide this general window of when they expect the flowers to be at their best. Admission is free, so if you're in the area come and enjoy the impressive 3,000 and 300 rhododendrons that decorate the grounds. It's a family-friendly event, with pets also welcome provided they are enclosed in a pet stroller.
