Hodosan Nagatoro

Wintersweet Nagatoro / Minano, Chichibu at Hodosan Robaien. The festival information is toward the bottom of the post.

In the hottest month of the year, I am nostalgic for the coldest month of the year. And judging by my blogs currently trending posts, it would seem I am not the only one. At the moment, the top three read posts of August 2019 are about January 2019. With the Ashigakubo Icicles event information webpage at number one.


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

Wintersweet in Japanese is Robai or “wax Japanese apricot”. It was named such 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.

When and where can I see wintersweet in Japan?

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. One of the most popular places to see the wintersweet in the greater Tokyo area is on Mt Hodo in Nagatoro in the Chichibu District of Saitama. (Although Kaminagano in Annaka, Gunma, has a much larger wintersweet garden).

Other places you can see wintersweet aka robai aka Japanese Allspice near Tokyo (External Website “Must Love Japan). And on this site: 10 places for wintersweet (robai) in Saitama Prefecture.

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):

The wintersweet begin to bloom from around the end of the first week in January until late February. Best viewing is end of January or early February. 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 Festival

For part of the period that the wintersweet are in bloom Nagatoro usually have a “wintersweet festival”. Followed shortly after by a plum blossom festival.

From January 29th to February 13th they will light up the wintersweet on Saturday, Sunday and public holiday nights only. For just a short period – from dusk to 7 pm.

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 (dates not yet decided for 2020) 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.
