Help To Identify This Gold Coin Please

Very interesting item. I think we have members here who can read some Japanese and translate the inscriptions.
I wonder if it is a commemorative medal or token (rather than a coins).

On one side we see a ship that looks like it could be one of the Portuguese trading ships from the 16th or 17th century that sailed to Japan:


On the other side we see a figure with the typical iconography of a saint (maybe holding a small book, and with a halo).

There were Potuguese Jesuit missionaries in Japan from the late 1500s until Catholicism was banned in Japan a few decades later. Maybe something to do with this?

I suspect this is a zodiac charm. When playing around with the 2 characters below the date I got the translation "Yang wood monkey". 2004 was the year of the monkey and Wood is one of the 5 elements so the owner was a wood monkey in terms of birth and fortune. Maybe the yang is to do with yin and yang? Not sure where the ship and other items fit in. A cool item though.

PS Can you please rotate photos so they are correct orientation when posting.

I'd say the side with the three Halo wearing entities overlooking a globe in the heavens might be Christian themed. I wonder if this is some sort of Church or other Temple specific medal/token. I presume the ship encasing is supposed to be a Lotus blossom.
