One of few surviving "radio towers" that were built before and during World War II has been gaining local attention in Nagoya, prompting residents to push for the important legacy to be preserved.
The radio tower in Shiga Park in Kita Ward is one of 460 that were built in parks and other locations throughout Japan to broadcast radio from built-in speakers and spread information swiftly.
But more than half of the towers have been taken down and very few people are even aware they exist.
