Wintersweet, also known as Japanese Allspice, or by its scientific name Chimonanthus praecox, is a winter blooming deciduous shrub that is most loved for its honeyed smell. Not that its appearance is too shabby either. The vibrant yellow of its wax like petals offers beautiful bursts of colour. And the best part is that it begins flowering when little else is, in the middle of winter. In Japan, that period falls in January and February.

Wintersweet Japan

In Japanese, Wintersweet is Robai (Roubai) 蝋梅 ロウバイ which is often translated as “wax Japanese apricot”. It was so named because of its resemblance to the ume tree, which is most commonly translated as a plum blossom but in Japan is said to be a Japanese apricot.

The wintersweet in the Kanto region (Greater Tokyo area) begins to bloom in early January, shortly after New Year and often when people are still on their New Year holidays. Mt Hodo, Nagatoro, is one of the most popular places to see the wintersweet in the greater Tokyo area. (Kaminagano in Annaka, Gunma, also has a large wintersweet garden).

Nagatoro Hodosan Robaien

A wintersweet garden or grove is called a robaien in Japanese. There are approximately 3000 robai / Japanese allspice / wintersweet in this grove. The Nagatoro Hodosan Robaien is at the top of the 497 meter high Mt Hodo. Beside the Hodosan summit shrine and close to Hodosan zoo. You can get to the top of the mountain and the wintersweet garden by hiking up the mountain or by using the Hodosan ropeway (on weekends):

Nagatoro Tourist Association report on the condition of the wintersweet during the bloom period. Last year, the wintersweet on Mt Hodo, Nagatoro, started to bloom on December 26th 2022. But in the 2024 season they were later to start blooming. Generally, they start to bloom from around the end of the first week in January until late February. Best viewing is at the end of January or early February. As of February 17th 2024 they are still in prime location in the west garden. Often you can see both wintersweet and ume plum blossoms together toward the end of February.

January is a beautiful month in Japan. Dry bright sunny days with clear blue skies. The bright yellow against the deep blue is a magnificent sight. And the smell is out of this world. Occasionally you can see snow at the start of January forging an even more impressive scene.

Wintersweet Nagatoro Access

The closest train station to Mt Hodo is the Nagatoro station on the Chichibu Tetsudo line (Chichibu railway). The official address of the wintersweet garden is actually Minano, but right on the border of Nagatoro. During the period of the official festival there is usually a free shuttle bus from the station to the foot of the mountain between the hours of 10 am and 4 pm.

From the foot of the mountain you can either hike up or take the ropeway. However, in January the ropeway only operates on weekends. Occasionally it will run on weekdays if there are a lot of tourists. Also, it sometimes is closed early January. You can check for information and hours on the official Chichibu Railway website. The ropeway costs 820 yen round trip (410 yen one way) for anyone over six years old.
