As others have said, refile asap. Also, never assume that USCIS already have documents - even if you are 100% sure that you included them - especially when mentioned in an RFE. Always send them exactly what they’re asking for, no matter if it has been submitted before. 

Just pointing out things about immigration here:

You will have an interview, regardless, and you will be scrutinized more for it being your second marriage to an international woman.  Additionally, when they see that the wedding took place prior to the actual requirement of meeting in person, that might also be considered a red flag - not to mention other factors like your age gap, how long you have been together, etc.  While some embassies/consulates/offices/service centers across the whole immigration journey move faster than others, in today's world, the difference between them are smaller than they used to, so for a CR1, it will still be around two years (you are looking at 2025) no matter which consulate or embassy gets your case.

If you have personal reasons for wanting/needing to be together in USA prior to the end of the year, you will need to adjust your expectations and consider other options that are not in the USA and DO NOT involve immigration fraud.

Best of luck and I hope it works out!

So you were scammed before yet you are committing to marrying a woman having never met her in-person?
You know what they say - fool me once... 

"Until I met an amazing woman in Brazil"
"I'm going to meet her and her son in person in August"
 
Making the acquaintance of someone via Internet is not meeting him or her.
 
Not only do I chime in with others' advice about meeting in person, embassy location, etc,  I'd say make extra sure, because there is a child. I've lost count of the threads on VisaJourney through the years about the challenges and stresses that a child entails when the child is only the man's or woman's child and not the mutual child. (Not to mention there's stresses when the child is the offspring of both immigrant and U.S. citizen.)

Think 2025.
 
Just to be clear you intend to marry someone online who you have never met?

1. Yes
2. you do not an embassy choice
3. be patient. Marrying someone you have not met is a bad idea. I suggest spending months together in total before marrying
4. good. 2 years vs 6
5. Expect more scrutiny
6. All cr-1 cases get interviews 

You haven't actually met, yet you are planning on marriage??  I would never recommend doing that.  That is not a good idea at all.
1.  Imo, a CR-1 is the best option. as she will be a legal resident with employment authorization upon entry.
2.  Your timeline is not realistic.  It will take closer to 2 years.
6.  You heard wrong.  There will be an interview.... in 18-24 months. Your miles may vary a little.
Good luck.

Why do you want to adjust status? Currently it will probably take 3-4 months before your wife is able to move to the US and she will have her green card upon entry. 
If she flies to the US and CBP 1.) knows she has an approved I-130 and 2.) is aware she wants to adjust she will be sent back to Japan.
You cannot travel to the US with the intention of adjusting status. Married to a U.S. citizen. Dating a US citizen. Approved I-130. No approved I-130. 

Holy hell this man is an Encyclopedia of information. Earned my follow 100%

First off, yay for your I-130 approval! That’s awesome, and from what I have seen, everybody in here is happy for you. 
Then, there is a clear distinction between a USCIS petition and a U.S. visa. Approval of the former means you’re eligible to apply for the latter. They’re also handled by two different departments (DHS vs. DOS). Worst case scenario for using wrong terminology in immigration means you make yourself ineligible for a visa. Nobody here wants that to happen to you, but we have seen our fair share of people who confused petition and visa and ran into trouble because they didn’t factor in the DOS side of things (NVC, consular, and all that). We’re trying to mitigate that and at the same time provide accurate info for everybody else who reads your thread. 
Finally, and somewhat off topic (mods, please edit if not allowed), I personally find it quite rude to make snarky comments toward long-term members in excellent standing such as @Crazy Cat or @SteveInBostonI130 while knowing full well that they took years (if not decades in some cases) to learn everything there is to know about immigration law, process, and timelines, and are willing to share their knowledge in a DIY forum for free.

You can translate documents, yourself, if you are fluent in English and that language.  Just attach and sign the following statement to the translation:
 

Please read Mike E's advice carefully.  Filing for your oldest child this week might save you a lot of worries, and money.  You can file for the others in the near future, but do not dismiss the benefits of taking care of your oldest' petition asap.

Congratulations
As everyone else said, WAIT and make sure you enter after the two-year anniversary, give it a week or two after the two-week anniversary before POE, just to be on the side and avoid any miscalculation

He had to redo his medical as we have been in administrative processing since December 2022. He just did his medical today so should be good for September.

definitely wait and make sure ur visa is not expired by then

As crazy cat says "Wait till after the 2nd year anniversary"
but watch the 6 month from medical exam date as that is when visa expires
September is only 3 months away /hold off as it will save u from going thru the ROC
