Two members of the Japanese Diet will visit Taiwan from Monday.
Former National Public Security Commission Chairman Furuya Keiji is chairman of a bipartisan group of lawmakers working to advance trade with Taiwan. Kihara Minoru is the general secretary of the group.
Both are members of the ruling Liberal Democratic Party.
Taiwan’s Foreign Ministry said it was to meet President Tsai Ing-wen, Vice President Lai Ching-te and other officials until Wednesday.
The ministry welcomed the visit and said it will further deepen friendly bilateral relations.
The ministry also said democracies should unite “at a time when authoritarian states are intent on invading and expanding overseas, causing regional tensions and challenging the order fundamental international”.
Earlier this month, Speaker of the United States House of Representatives Nancy Pelosi became the highest-ranking Washington official to visit Taiwan in 25 years.
China responded by staging massive military exercises around Taiwan, including ballistic missile launches.
Another group of US congressional lawmakers visited Taiwan last Sunday.
Taiwan values diplomacy with lawmakers from countries without formal relations, including Japan, the United States and those in Europe.
