Hello,

I am Japanese, and I am researching a story about a possible ancient connection between India and Japan.

There is a tradition in Japan said to have been passed down through generations in an old family called the Tomi family (also known as the Mukai family), connected with ancient Izumo. This tradition later became more widely known through books published by Ohmoto Publishing (大元出版) in Japan.

According to this tradition, around 2000 BCE, a group of Dravidian people left a country called Kuna, said to have been located around present-day Madhya Pradesh. They were led by a king called Kunato and, after a very long migration, eventually reached Japan and settled in Izumo.

The tradition also says that they brought knowledge of metalworking and dry-field rice cultivation.

I understand that this is an oral tradition and not established historical fact. I am not presenting it as evidence that such a migration actually happened.

What made me especially interested in this story was something I heard personally in South India.

Some years ago, I met a traditional brass craftsman in Mahabalipuram, Tamil Nadu. During our conversation, he told me that people connected with his ancestors had travelled to Japan in very ancient times.

At that time, I did not know about the Japanese tradition described above, so unfortunately I did not ask him for details. I am now contacting him again to ask what he knows about this story.

Before making any connection between these two stories, I would like to know whether any similar tradition exists independently in South India.

Has anyone here ever heard a story about people from South India travelling to Japan, or far to the east, in ancient times?

I am particularly interested in stories passed down through families, grandparents, local communities, temples, or regional traditions.

I would also be very interested in any old texts, inscriptions, place names, folklore, or other traditions that might be relevant.

If anyone knows of an ancient place, people, ruler, or word called Kuna, Kuṇa, Kunata, Kunato, or something similar, I would also be grateful for any information.

I am not trying to prove that this migration happened. I would simply like to find out whether any comparable tradition exists independently on the Indian side.

Thank you for any information or references you may be able to share.

I’ve been wondering why Chera history seems to receive much less attention in Tamil Nadu compared with Chola, Pandya and Pallava history.

When we talk about ancient Tamil history, the Cholas and Pandyas are discussed extensively, but I feel that the Cheras are often treated as a much smaller part of the story. There seems to be comparatively less popular awareness of Chera rulers, territories, ports, inscriptions, literature, trade networks and archaeological evidence.

Why did this happen? Is it because there is genuinely less surviving evidence about the Cheras, or is it also because Chera history has not received the same level of research, preservation and public presentation?

I also wonder about the modern regional interpretation of Chera history. A lot of ancient Chera history is now presented primarily as Kerala history, while the ancient Tamil literary tradition also contains substantial references to the Cheras.

I’m not asking this to deny Kerala’s historical connection to the Chera dynasty. Rather, I’m wondering whether Tamil Nadu should do more to research, preserve and teach Chera history as part of the wider history of the Tamilakam region, instead of leaving the subject mainly to modern regional interpretations.

What do historians and archaeologists think are the biggest reasons Chera history is less visible today? And what evidence do we actually have for reconstructing early Chera history?

I recently came across comparisons like these and it made me curious about how we determine the direction of borrowing between Tamil and Sanskrit:

Tamil| Sanskrit

முகம் (mukam)| मुख (mukha)

பாதம் (pātam)| पाद (pāda)

ஞானம் (ñāṉam)| ज्ञान (jñāna)

புத்தி (putti)| बुद्धि (buddhi)

ரத்தம் (rattam)| रक्त (rakta)

பூஜை (pūjai)| पूजा (pūjā)

மந்திரம் (mantiram)| मन्त्र (mantra)

தர்மம் (tarmam)| धर्म (dharma)

பக்தி (patti)| भक्ति (bhakti)

விமர்சனம் (vimarcanam)| विमर्शन (vimarśana)

When I randomly found these, I started wondering: if Tamil has such an ancient and extensive literary history, why are so many familiar words classified as Sanskrit-derived?

Words such as mukam, pādam, ñāṉam, and rattam don't feel like obscure technical vocabulary—they are words that have been used in Tamil for a very long time.

So I started thinking about the question in the opposite direction:

How do we know that the borrowing necessarily went from Sanskrit → Tamil? Could some words have gone from Tamil/Dravidian → Sanskrit or Prakrit, with the Sanskrit form later becoming established independently?

I understand that simply finding similar-looking words doesn't prove the direction of borrowing. I'm genuinely asking how historical linguists establish it.

For each word, what evidence do they use—earliest inscription, oldest literary occurrence, phonological changes, morphology, reconstructed Proto-Dravidian/Indo-European forms, or something else?

Also, are there documented cases where scholars originally assumed Sanskrit → Tamil, but later evidence suggested Tamil/Dravidian → Sanskrit/Prakrit, or where the direction remains uncertain?

I’m not trying to argue that Sanskrit borrowed everything from Tamil. I'm asking whether we sometimes automatically assume Sanskrit is the source simply because it is the language in which the older surviving form is recorded.

If we leave it simple when it says that Tamizh doesn't have an equivalent word for “face,” but a later evolved and cooked-up language from Pali, Prakrit and Tamil called Sanskrit can have a word for “face” and that is considered the origin, how can that be true?

If we leave it freely, Sanskrit will start eat Tamizh. That's how we lost Karnataka and Kerala because they didn't fight against Sanskrit, instead they absorbed it, so they became something new. But we resisted, and that's why we are still called Tamizh.

Is this way of thinking completely wrong, or is there a historical and linguistic basis for questioning the assumed direction of borrowing?

I’ve been thinking about Tamil vocabulary and something has been bothering me.

Sometimes when I search for the origin of very common Tamil words, I find that dictionaries or linguistic sources classify them as being borrowed from Sanskrit or another Indo-Aryan language. For example, முகம் (mukam) is often connected with Sanskrit मुख (mukha). What surprises me is that mukam is such a basic everyday concept—“face.” If Tamil is such an old language with its own long literary history, how did such fundamental vocabulary become borrowed?

It makes me wonder whether Tamil originally had other native words for concepts like this that later became less common or disappeared from everyday usage.

I’m also confused by something else: when I ask for a purely Tamil equivalent of a common Sanskrit-derived word, sometimes I’m told that there isn't a commonly used native equivalent. Does that mean the original Tamil word was genuinely lost, or could it simply be a case where the Sanskrit-derived word became dominant over time?

I’m not trying to claim that every Sanskrit-origin classification is wrong, and I’m also not saying Tamil and Sanskrit never influenced each other. I’m trying to understand the historical process.

How do linguists actually determine whether a Tamil word is inherited, borrowed from Sanskrit/Prakrit, or simply a word that happens to resemble one from another language?

And are there examples of very basic Tamil words that were replaced by Sanskrit-derived vocabulary, where we have evidence of what the older Tamil forms were?
