The following five World Heritage Sites within the Cultural Triangle of Sri Lanka share a closely intertwined history.
- Sigiriya Rock
- Candy
- Polonnaruwa
- Anuradhapura
- Dambulla Cave Temple
Understanding the historical background deepens one's appreciation of each World Heritage site, allowing for a greater sense of wonder.
Even those who studied world history at secondary school are unlikely to have studied Sri Lankan history.
Today, I would like to explore the history of tradition and invasions from other nations in chronological order.
Ancient to Medieval Sri Lanka under the Sinhalese Kingdoms
The history of Sri Lanka began with the Sinhalese dynasty.
However, having repeatedly suffered invasions by the neighbouring great power, the Indian dynasty, it relocated its capital numerous times before finally disintegrating.
The five World Heritage sites clustered within the present-day Cultural Triangle all trace the rise and fall of the Sinhala Kingdom up to the medieval period.

Portuguese colonial era
From the Middle Ages onwards, a bitter and protracted period of subjugation by the European powers would continue.
First came the colonial era under Portugal.
The fortress of Goa, now a World Heritage Site, was constructed during the Portuguese colonial era.

The colonial era under the Netherlands and Britain
Following Portugal, the Netherlands and subsequently the British Empire would colonise Sri Lanka.
In the 19th century, the Kingdom of Kandy, the last Sinhalese dynasty, was overthrown.
However, it was during this period that the British Empire commenced the cultivation of Ceylon tea, which would come to underpin the economy of present-day Sri Lanka.

From Independence to the Present Day
It was in 2009 that Sri Lanka, where conflict persisted even after independence, regained peace.
Since then, it has achieved remarkable economic growth through the realisation of peace.
Large-scale projects such as resort development and infrastructure improvements are currently underway, propelling the area's rapid advancement as a tourist destination and attracting increasing numbers of visitors from Japan.

| 2015 | The UNP has won. It has formed a grand coalition with the second-largest party, the SLFP. |
It was Sri Lanka that saved defeated Japan.
Why did Japan establish diplomatic relations with Sri Lanka first, as shown in the earlier chronology?
It expresses our profound gratitude to Sri Lanka, for which we Japanese cannot thank them enough.
Did you know that after the Second World War, there was actually a proposal for Japan to be divided and governed by the victorious nations?
At the 1951 San Francisco Peace Conference, a proposal for the partition and administration of Japan by the United States, the United Kingdom, the Soviet Union, and China was put forward.
How dreadful.
It was the speech delivered by former Sri Lankan President Jayawardena at the San Francisco Peace Conference that became Japan's saviour.
The following is quoted from the Japanese Embassy in Sri Lanka.
The late President Jayawardena attended the 1951 San Francisco Peace Conference as the representative of Ceylon (then Minister of the Treasury),
Hatred ceases only by hatred, and is overcome by love.Hatred ceases not by hatred, but by love)」
He delivered a speech quoting the Buddha's words, clearly renouncing claims for reparations from Japan and appealing for our nation to be accepted as a member of the international community.
This speech is said to have swayed even some of the victorious nations that had been demanding severe sanctions against our country at the time,
It is remembered as one symbolic event that paved the way for our nation's subsequent return to the international community.
Furthermore, the following description also appears on the Prime Minister's Office website.
As you are all well aware, it was the then Ceylon Finance Minister, Jayawardena, who delivered the speech defending Japan's sovereignty at the 1951 San Francisco Peace Conference.
The form of Japan as a nation today owes much to the significant impetus provided by that speech.
Let us bear in mind that it is thanks to distant Sri Lanka that Japan's national polity has been preserved to this day.
Summary
Sri Lanka, which has endured continuous aggression from India and European colonial powers from its founding to the present day.
Yet, even amidst a history of invasions, it sublimated its Buddhist culture, leaving behind numerous World Heritage sites for the present day.
We Japanese must not forget our close ties with post-war Japan and our gratitude towards Sri Lanka.
Following the end of the civil war in 2009, the country has embarked on substantial economic development and infrastructure improvements, steadily establishing its position as a major tourist destination.
Why not pay a visit to Sri Lanka, a country that has bestowed such great kindness upon us and is home to World Heritage sites?
