In Photos: The marriage of former Princess Mako and Kei Komuro - The Mainichi
Some translations until the full remarks and written answers are available...
M: Kei is irreplaceable to me
K: I will do my best to solve my mother's financial trouble. I want to [do it]
"At press event (former Princess) Mako & Kei Komuro apologized to people they caused trouble for, who disagreed with their marriage. They thanked their supporters. Kei said: I love Mako; You only live once and I want to spend my one life with the person I love"
"First time the couple is addressing public in years. Kei says "misinformation has been spread" & he's saddened by Mako's PTSD & what his mother has been through. "She had no choice but to quit her work & felt unsafe""
Folks can Google translate the following:
Mainichi 1 - Mako's remarks. Sympathies to those people suffering during the pandemic, gratitude for her Imperial life and support received, grateful for those who worried and supported her, recognizes opposition to marriage, etc.
Mainichi 2 - Kei's remarks. Loves Mako, apologizes for the inconvenience caused by this marriage, thanks Mako for her support, etc.
Mainichi 3 - Mako's remarks continued. Moving abroad was her idea?
"... Kei hasn't moved on his own since the news about his engagement. For example, Kei's mother's response to her ex-fiancé proceeded in the direction I requested. Regarding Kei-san's study abroad, I asked him to set up a base overseas ahead of schedule for Kei-san's future study abroad program. I couldn't help at all when studying abroad, but I am grateful that Kei made an effort in a difficult situation."
Mainichi 4 - Kei's remarks continued. No progress on financial dispute. Ex-fiancé wants to meet his mother.
"...As I wrote in the published document, I have occasionally thanked my [mother's] ex-fiancé from time to time, and I am still grateful. When I proposed a solution by handing a settlement fee in April this year, I received a reply that it was important to meet [my] mother. However, [my] mother is mentally ill and doctor stopped her from meeting her ex-fiancé..."
Mainichi 5 - Kei remarks about wanting to resolve financial dispute, sorry about Mako's PTSD, his mother's mental illness, her quitting her job because she felt in danger.
Mainichi 6 - Mako's remarks/end.
"...We will start a new life together. I think there will be different forms of difficulty in our lives. However, as has always been the case, we would like to work together and walk together.
Until now, we have been faithful to our hearts because of each other's existence and the existence of people who encourage and support us..."
ETA: Mako and Kei's
written responses to 5 questions
Princess Kako's statement on her sister's marriage. She supports Mako and Kei
Crown Prince Akishino and Crown Princess Kiko's statement on the marriage. Apologizes to the public for the uproar/trouble. Acceptance/hope for the best vibe.
I'm hoping English versions of Japanese media (Asahi, Mainichi, Kyodo, etc.) will provide full English translations.
