Kohat Tunnel: The Pak-Japan Friendship Tunnel

What the Kohat Tunnel is, its history, length and route between Kohat and Dara Adam Khel, and current safety advice for the road it sits on.

By Explore Pakistan · Published 25 September 2026 · 4 min read

The Kohat Tunnel is a 1.89 km road tunnel on the N-55 Indus Highway, carrying traffic under the Khigana hills between Kohat city and Dara Adam Khel. Built with Japanese development funding and opened in 2003, it is officially known as the Pak-Japan Friendship Tunnel and replaced the older, narrower road over the Kohat Pass.

This guide covers the tunnel's history, what the route through it involves, and the current security situation, since it sits inside a district the UK government currently advises against all travel to.

Why the tunnel was built

Before 2003, traffic between Kohat and Peshawar on the Indus Highway had to climb over the Kohat Pass, a narrow, winding road through the hills that was slow for ordinary traffic and difficult for larger vehicles. The tunnel was built to cut that journey, funded mainly through Japanese official development loans, which is why it carries the Pak-Japan Friendship Tunnel name.

Construction began in 1999 and the tunnel opened to traffic in 2003. At 1.89 km it was, at the time, one of the longer road tunnels in Pakistan, cut through the Khigana range south of Kohat city.

What the drive is like

The tunnel itself is a straightforward, lit, two-lane bore, wide enough for trucks and buses as well as cars, with a clearance of about 3 metres. It shortens the journey and avoids the switchbacks of the old pass road, and it is used constantly by the heavy commercial traffic that runs the length of the Indus Highway between Peshawar, Kohat, Bannu and further south.

On the far side, the road runs into Dara Adam Khel, historically known across Pakistan as a centre for locally made firearms sold from shops along the road. Both the tunnel approach and Dara Adam Khel sit within Kohat district and carry the same current security advice.

Is the Kohat Tunnel safe to use?

The tunnel and the district it sits in are covered by the UK government's advice, updated 22 September 2026, against all travel to Kohat. This follows a serious attack on Kohat's Police Lines on 18 September 2026, when a suicide car bomb and armed assault on a mosque inside the police compound killed at least 23 people, including 17 police officers, and injured more than 100 (Dawn). Kohat and the surrounding districts have also seen a longer pattern of militant activity connected to the former tribal areas nearby.

The road through the tunnel remains the main route south from Peshawar for freight and local traffic, and it functions day to day. It is not, at present, a stretch to travel for its own sake as a tourist. If your route genuinely requires it, travel in daylight, check recent local news beforehand, and follow any checkpoint or police instructions along the way. Visitors from overseas should check their own government's current advice, since travelling against it can affect travel insurance.

Who needs to use this route?

Mostly through-traffic: freight moving along the Indus Highway, and people travelling between Peshawar and points further south such as Bannu or Dera Ismail Khan. It is not a scenic drive or a destination in itself, and there is little reason to route a leisure trip through it while the current advisory stands.

For places on the Indus Highway further south, our guide to Dera Ismail Khan covers the safer alternative of travelling via the M-14 motorway rather than the Indus Highway through Kohat and Bannu. Our wider guide to places to visit in Kohat covers the rest of the district.
