With 50 days to go, fans from around the world are expected to descend on Japan during the tournament, beginning in late September and going through to mid-November.
It is the first World Cup to be held outside of rugby’s traditional heartlands.
Ever since the venue of the final was changed in 2015 after the scrapping of a proposed new national stadium, planning for the World Cup has been mostly smooth.
World Cup venues – Kamaishi, Osaka and Kumagaya – are hosting Japan warm-up matches, which should give organisers a chance to fine-tune their final preparations.
“The key operational aspects of the tournament are in good shape,” Japan 2019 chief executive Akira Shimazu told Reuters.
“We are testing and fine-tuning our operations across the two Pacific Nations Cup matches and the warm-up match between Japan-South Africa at Kumagaya.”
