It's the first week of November 2019 in Tokyo. Autumn is in the air, and an era is ending for Welsh rugby. In under 12 years at the helm, Warren Gatland has guided Wales to three Grand Slams, a Championship and two World Cup semi-finals. He's overseen a record-breaking 14-match winning streak, five of only six Wales wins ever over South Africa, and first back-to-back victories against Australia since the 1970s. Surely he's been the greatest Wales coach ever?
This is the story of Wales' adventures in Japan in 2019, their last campaign under Gatland. A story of hope and heartbreak, of giving it all you've got, and of atanding dumbfounded as 15,000 Japanese fans in a remote corner of the country sing "Hen Wlad fy Nhadau" in word-perfect Welsh. It's also the story of how, in the face of the biggest typhoon in 60 years, the Japanese people came together to stge the biggest and best rugby tournament so far.
