The move is intended to minimize damage during natural disasters, but is it too little too late?

No matter where you travel in Japan, you’re likely to see one familiar sight wherever you go—utility poles, threaded together by thick power cables. These cables carry electricity all over the country and are much cheaper to install and reach for repairs than their underground counterparts. A country that works late into the night and begins again early the next morning needs a stable system to transport all that power to where it’s needed. But unfortunately, overhead power lines aren’t without their risks. They’re easily threatened by natural disasters like earthquakes, typhoons, and tsunamis, which can dislodge them and disrupt power service on a huge scale.

So why is Japan still using them? Well, the issue is that changing from overhead to underground power lines is no small feat, and it has an appropriately huge price tag to match. Though talk of removing power lines have increased in surrounding the Tokyo Olympics, the huge utility poles are still looming all over Japan. It takes time not only to remove the power cables themselves but also to implement new cables into an underground system that already includes a thriving network of water and gas pipes.

The Ministry of Land, Infrastructure, Transport, and Tourism has, however, announced a new plan to eliminate 4,000 kilometers (2485.48 miles) of overhead power cables at sites across the nation by 2025. Their priority will be areas around roads that help to transport goods in the case of emergency situations, as well as cables along roads leading to World Heritage Sites and other popular tourist destinations. They cited improved disaster response and beautifying the landscape as the motivating factors behind the plan.

▼ Citizens often complain about the clutter of utility poles and cables alike.

Running counter to this is the fact that around 70,000 new utility poles are installed every year. The government assures that they will be interacting with power companies to try to bring this number down and seek out alternatives for transmitting energy across the nation.

The issue of power cables has earned much more attention in recent years, especially after a typhoon in September 2019 that left vast areas of Chiba prefecture without power. While the new plan aims to address critical areas for disaster response, citizens have criticized both the relatively small scale of the cable removal and the long window of projected time it will take to even remove that. On the other side of the debate, there are also people staunchly against the implementation of underground cables, who imply that the much greater ease of repair to overhead lines more than offsets their higher risk of being damaged in the first place.

“Just 4,000 kilometers? Isn’t it way too late for that? And when are they planning to start? Hurry up and get it over with already!”
“The Ministry of Finance better not get in the way of this. Heck, they should double their budget for it.”
“This is just gonna make it even harder to restore power after earthquakes or natural disasters. Stop this plan.”
“It’s not exactly encouraging to think that it’ll take five years just to get rid of 4,000 kilometers…”

For every person who complains about how ugly the overhead cables look, there is another arguing that the utility poles supporting them are important to mark streets or provide light. The ultimate fate of Japan’s overhead power cables remains in the dark for now, but we’re eager to see how what changes may happen in the next four years.
