The UK and Japan have agreed on a three-year defence cooperation plan to strengthen their security and defence relationship.
In August, UK Prime Minister Theresa May and Japan Prime Minister Shinzo Abe committed to cooperate together on defence issues.
The countries will work together for operations across air, land, and sea in the Asia-Pacific region.
UK Defence Secretary Gavin Williamson said: “Japan is one of our closest partners in the Asia-Pacific region and as tension grows on the Korean peninsula, our relationship is vitally important.
“2018 will mark the year UK and Japanese forces work even more closely together, with two of our Royal Navy frigates visiting the country and UK troops training on Japanese soil for the very first time.”
The British Royal Navy’s HMS Sutherland will visit Japan next year and HMS Argyll will also take part in exercises in the country next year.
Additionally, the UK will send close to 45 personnel from the British Army to train with Japanese soldiers next year.
The UK will also continue to work closely with the Japanese Self-Defense Air Force, with plans for future joint-working.
A Royal Navy captain and five medics will also be sent to the US-led Pacific Partnership deployment, which will provide humanitarian and disaster relief training to military and civilian organisations.
