Made in Japan Yomeimon Gate book end? help with age

Hi all I hope someone can help with dating this piece. made of cast metal on a wood base. You can see from the side view that they used to be attached.
With the base it measures 6" x 6" x 3"
Casting is good but not great. I was told it was Pre-war. That would make it after 1921.
and before 1944. I was guessing late 40s but then it would be occupied Japan, right?
I'm not totally sure it's a bookend either. may be an altar piece. I appreciate any thoughts. I have showed it to a few of my collector friends and by majority the initial thought is late 1930's

I found one that looks a lot like yours but better casting and a few more details. Also on a wooden base. Not sure if this will help:
