How to understand Japanese working man

Good day,
Please answer my question , how do Japanese working men devotes their time or self to the women they wanted to be with?and, how could I distinguish his intention?
Please tell me Japanese Attitudes.
Thank you so much.
I hope I didn't offended you.

Is he your boyfriend or husband? Is this an online relationship? A real life relationship?

what is his blood type?

Japanese attitudes are dependent on the individual person. We can't possibly gauge what someone is thinking without knowing them. It's best that you talk with him about it.

Any man, who is really in love, will make time for his woman.

If he's always busy, can never be reached by his cell phone, or calls you then disappears for a while, consider him not interested or a player.

If he's really interested in you, he'll ask you to join him for many things: dinners, drives, lunches, etc.

My J-husband took a day off work to meet me for our first date. That was pretty big in my mind, because work for Japanese men is usually priority #1. After that, he invited me fishing, hikes in the mountains, basically, all the things he liked to do, he asked if I would join him.

J-men are just men everywhere in the world; if he likes you, he'll make time to see you. If not, consider him not so interested. ^_^

I hope that helps.
