How to move with husband at the same time

Japan is opening up but we're waiting a little bit longer. Our biggest issue, though, is arriving with my husband at the as I arrive. I will be under a working/ Humanities visa. My husband will be under a dependent. I understand I need to apply for his COE as well but that requires me to go to Japan first. It seems almost impossible and I'm at my wits end. It seems like not a single person in this world has been able to go together with these two visas. Please, any advice will be greatly appreciated and I'm exhausting options.
(For more detail, I will be working with NOVA. They do not assist with spouses or housing so we're on our own.)

Not from a country included in the visa waiver program?

If yes. He turns up as a tourist for 90 days. In that time, you get a coe/cos for him.

it is not a problem of immigration system.
there is no restriction that you can't get a dependent visa simultaneously.
for your case, the only problem is "no helping from NOVA".
find a new company, which helps you to do that.
but, generally speaking, by the consideration from posts in this forum, it seems that English conversation schools are not friendly for new coming foreigners.
another drawback is that NOVA has a history of bankruptcy.

Regarding the tourist idea from PP, in normal times yes, but remember, the boarders are still closed for tourists.
