Anti-nuclear campaigner and former prime minister of Japan, Naoto Kan, will meet with the farmer refusing to sell his land to Wylfa.
Richard Jones' farm on Anglesey has been earmarked for part of the £8 billion nuclear power plant.
It's the second day in Mr Kan's visit to Wales. He wants the plans for the nuclear plant to be scrapped.
Yesterday, he held a public meeting at the Pierhead building in Cardiff Bay.
Naoto Kan was prime minister of Japan at the time of the Fukushima nuclear disaster.
The power plant was hit by a Tsunami in 2011, causing the largest nuclear incident since the Chernobyl disaster. It led to his resignation.
Mr Jones will be giving Mr Kan a tour of the land which will be followed by a public meeting at Llangefni.
