There is much to talk about between the two.
As a side note, both are noobs! Suga took over as Japanese Prime Minister when Shinzo Abe resigned due to poor health in mid-September. (I should clarify, noobs to their respective top jobs, each has vast experience in government).
Suga and Biden will be discussing, amongst other things:
- addressing the COVID-19 pandemic (which is still accelerating in the US but happily under control in Japan)
- trade
- discontinuing US appeasement of North Korea
- the Japan-US security alliance
