Why Are Australian Gum Trees All Over Japan?

なぜ日本にはオーストラリアのユーカリがこんなに多いのか?

Look around many Japanese parks, university campuses or botanical gardens and you’ll probably spot a gum tree. Most people walk past without a second thought. Yet these unmistakably Australian trees have quietly become part of Japan’s landscape.

日本の公園や大学、植物園を歩いていると、ユーカリの木を見かけることがあります。しかし、多くの人はそれがオーストラリア原産だとは気付きません。今では、ユーカリは日本の風景に静かに溶け込んでいます。


An Aussie Arrives in Japan

オージーの木が日本へ

Eucalypts are native almost exclusively to Australia.

The first specimens arrived in Japan during the late 19th century, when the country was eagerly introducing plants from around the world for scientific study and forestry trials.

Botanical gardens played an important role in testing which species could adapt to Japan’s climate.

オージーの木が日本へ

ユーカリは、ほぼオーストラリアだけに自生する樹木です。

19世紀後半、日本が世界中から植物を導入していた時代に、ユーカリも研究や試験植林のため持ち込まれました。

植物園は、日本の気候に合う種類を調べる重要な役割を果たしました。


More Than One Tree

ユーカリは一種類ではない

Many people think “gum tree” means a single species.

In fact, there are more than 700 species of eucalypts.

Only a small number thrive in Japan, but those that do can be found from Hokkaido to Okinawa in parks, arboretums and university collections.

ユーカリは一種類ではない

「ユーカリ」は一種類の木だと思われがちです。

実際には700種以上が知られています。

日本で育つ種類は限られますが、北海道から沖縄まで、公園や植物園、大学の研究施設などで見ることができます。


A Favourite of Koalas—and Beekeepers

コアラだけの木ではない

Koalas made eucalypts famous around the world.

In Japan, however, the trees have found different admirers.

Some species are valued for their attractive bark and fragrant leaves, while others are planted by beekeepers because their flowers produce abundant nectar.

コアラだけの木ではない

ユーカリといえばコアラを思い浮かべる人が多いでしょう。

しかし日本では、それ以外の魅力でも親しまれています。

美しい樹皮や香りの良い葉を楽しむ人もいれば、蜜源植物として注目する養蜂家もいます。


A Living Symbol of Friendship

生き続ける友好のシンボル

Today, Australian eucalypts grow in botanical gardens, schools, parks and private gardens across Japan.

Some have been planted to commemorate Australia–Japan friendship or international exchange.

Each tree is a quiet reminder that ideas—and plants—travel remarkably well.

生き続ける友好のシンボル

現在では、日本各地の植物園や学校、公園、庭園でユーカリを見ることができます。

中には、日豪友好や国際交流を記念して植えられた木もあります。

一本一本が、植物も友情も国境を越えることを教えてくれます。


An Unexpected Taste of Home

オージーにとっての故郷の香り

For many Aussies living in Japan, the scent of a gum tree is instantly familiar.

A warm day can release the distinctive aroma of eucalyptus leaves, bringing back memories of home.

It is a small but powerful reminder of the ties that have grown between Australia and Japan.

オージーにとっての故郷の香り

日本で暮らす多くのオージーにとって、ユーカリの香りは故郷を思い出させる特別なものです。

暖かい日に葉から漂う香りは、オーストラリアで過ごした日々をよみがえらせます。

それもまた、日豪交流が育んだ小さな贈り物なのです。


An Unknown Nichigo Story

「知られざる日豪交流」の物語

Trade figures measure commerce.

Diplomatic visits measure politics.

But a gum tree growing quietly in a Japanese park tells a different story.

It reminds us that Australia and Japan have been exchanging ideas, science and nature for well over a century.

「知られざる日豪交流」の物語

貿易額は経済を表し、首脳会談は外交を表します。

しかし、日本の公園に静かに立つ一本のユーカリは、別の物語を語っています。

それは、日豪両国が100年以上にわたり、植物や科学、そして文化を分かち合ってきた証なのです。


Did You Know?

Japan is home to dozens of cultivated eucalypt species. The largest collections can be found in botanical gardens and research institutions, where scientists study their growth, cold tolerance and potential uses in forestry and horticulture.

豆知識

日本では数十種類のユーカリが栽培されています。特に植物園や研究機関では、耐寒性や成長特性、園芸・林業への活用について研究が続けられています。

Cop A Gander At These Rippers Too...

  • Arse Wind?

    Walking along Route 246, I was surprised to look up and see the katakana script reading アースウィンド!  びっくり仰天だった! アースis, in English, arse…or, so I thought. Arse wind, then, could only mean one thing….surely a company couldn’t have named itself after a fart? Of course it didn’t. In fact, アース is also the reading for earth. That makes Earth Wind a little easier to comprehend, even if the English is still a little awkward.

    Australia Wants You…Again! Another Embassy Opening

    The Australian Embassy in Tokyo is advertising another position. This time, it’s looking for a Consular and Passports Officer to deliver essential services that support the wellbeing and safety of Aussie citizens abroad. Like last week’s posting for a Strategic Communications Assistant, this job would be an awesome chance for someone to contribute to building better relations between Australia and Japan. I’ve met lots of Embassy folks and they’re a very decent bunch of people blessed to have the wonderful job of serving Australia’s interests in Japan. Application details here:

  • Self-Portraits

    Kangaeroo was once an almost ubiquitous presence on the Internet. That was, of course, back in the days before the likes of Facebook, Twitter and other social media dominated online viewing. Even blogs were in their infancy and Google still provided results for terms that people searched for and not for the highest payers. But that all changed. Decades have passed since Kangaeroo posted a portrait online. But that has changed with this post. These are photos of Kangaeroo now. Definitely wasn’t worth waiting for! Not that I think anybody actually waited….

    Up And Away Over The Clouds On A Brompton

    My Brompton folding bike has proved to be more of a handful than I’d hoped with its unique parts costing a lot to maintain, but it is also lifting me to new heights in cycling, literally this month as I rode the Norikura skyline. The Norikura Kogen skyline is one of the highest elevation roads in Japan and I got a shock riding down a mountain for the first time, especially as I was carrying a heavy load. I rode my brakes nearly the entire descent of roughly 15 km, which started in pleasant sunshine, but ended in a mist. I had no idea how to descend properly, and when…

  • Do Little

    Blessed with a bit of time and being in close proximity, I used the beautiful weather to visit Tama Zoological Park, testing a new Nikon Z 50 camera. I first visited this zoo in 1993, at a time when the memory of the 1984 arrival of koalas was still fresh. Koalas were flavor of the month in Japan at the time, literally so in the case of Koala no March–a confectionary that remains popular to this day–and the zoo’s Australian Habitat was something of a showcase area. Now, it’s just one of many habitats in what is a delightful little zoo nestled into the Tama hills. KOALA-IFIED TO SELL Though…
