You have no choice but to ask DMM to :

1. Contact customer support, fill the form to change your email address, or

2. Contact customer support, ask them simply remove the force password reset for once so you can change your email address yourself

Unless you can talk in Japanese and call their hotline, you should tell them you have no Japanese phone number (私は日本での任意の電話を持っていません)

Not the usual method, but mailing to info@mail.dmm.com their staff may reply your request. You must proof you are the account owner by answering their questions (you can google translate those japanese)

Topic can be like this パスワード再設定不能,どうぞよろしくお願いします

There should be a list of questions they need you to answer in their account recovery page, copy it and fill them (such as DMM in-game name, email address, DMM services - in this case, 艦これ, unless you have other games too, credit card number if any... etc

Dont forget to tell them you cant call their hotline (私は日本での任意の電話を持っていません)

That is not the first case, Starting from Early June (or even May?) there are lots of report that yahoo failed to receive DMM emails. well, i don't have any credit card nor japanese phone (and i can't speak japanese). but i think i'll try it. i began to suspected that yahoo got busted last week after i got this problem.
