PRIME MINISTER KISHIDA:  Thank you. Mr. President, Dr. Biden, distinguished guests, and ladies and gentlemen, I would like to express my heartfelt gratitude to you for hosting such a wonderful dinner and your warm welcome and hospitality.
Before I came here, my protocol staff told me that no one had ever complained that my speech was too short.  This is probably good advice.  So, I’ll keep my speech short. 
First and foremost, to be honest, my breath is taken and I’m speechless in front of such a huge number of prominent American and Japanese guests.  My wife, Yuko, also left breathless, just told me that it was hard to tell who the guest of honor is.  So, I was relieved when I was shown the seat right next to the President. 

Last year, President Biden and Dr. Biden visited my hometown of Hiroshima to attend the G7 summit meeting.  It is a little-known fact that the largest number of Japanese immigrants to the United States came from Hiroshima.  Many Hiroshimans headed to the United States to seek a new world, a better future, and greater heights. 
Mr. President, I know that the late Senator Daniel Inouye was a good friend of yours. 
PRESIDENT BIDEN:  He was.
PRIME MINISTER KISHIDA:  His mother was also from Hiroshima. Looking back at the long history of Japan and the United States, our predecessors have carved out the path in various fields, such as business, academia, art, and sports, traveling back and forth between the two countries. 
“The Pacific Ocean does not separate Japan and the United States.  Rather, it unites us.”  These were the words that President Kennedy sent to Prime Minister Ikeda, also hailing from Hiroshima, at the state luncheon held at the White House about 60 years ago.  
I like this line.  I — I use it so many times that my staff tried deleting it  whenever this phrase appeared on speech drafts.  However, there is nothing that expresses our relationship as visibly as this.  And never have these words been more relevant than today.  Japan and the United States are united than ever before.   
I believe that the Pacific Ocean has brought Japan and the United States together and so close because of the pioneering spirit of those who came before us and frontier spirit that we all have in common.  The success of those standing on the frontier is not just because of their individual efforts but also the result of collective efforts as a team.  This hol- — this holds true even between nations. 
Our joint efforts are (inaudible) indispensable for our bright future and for the peace and stability of the world.  We are now standing at a turning point in history, embarking on a new frontier and elevate this unshakable Japan-U.S. relationship to even greater heights and hand it to the next generation.   
And, finally, let me conclude with the line from “Star Trek” — (laughter) — which you all know: “To boldly go where no one has gone before.”  
By the way, George Takei, who played Hikaru Sulu, the helmsman of the USS Enterprise, also has roots in Hiroshima.  
Mr. President, Dr. Biden, distinguished guests, and ladies and gentlemen, I would like to propose a toast to our voyage to the frontier of the Japan-U.S. relationship with this word: “boldly go.”
PRIME MINISTER KISHIDA:  Thank you.
PRESIDENT BIDEN:  Hear, hear.
PRIME MINISTER KISHIDA:  And “boldly go.”  Cheers.
