If I understand your problem, the housing is spinning and the filter is not loosening. If that is correct. The only thing I would do is get the cover off of the filter assembly. You will have to somehow cut into the FILTER HOUSING ONLY. Peel it off and then either with vise grips or something slowly work your way to where the shaft is that has the threads going into the block. Again it might take a vise grip to clamp on it and break it free. If this is the issue, ONLY destroy the oil filter, being especially careful of the threaded assembly going into the block, do that you don't damage the threads in the block. Maybe there is another way, if so maybe another of our brethren will share it. Don't be afraid to use a lot of penetrating oil sprayed into the area of the threads into the block. Let it sit a half hour or so and then tap it, see if it frees up. Don't skimp on penetrating oil. You can clean up the excess later.
Good luck!

Poke a hole strait through the middle of it with a screwdriver if the casing is spinning.Never seen that before though.
I'm thinking that your fancy filter wrench just isn't grabbing the filter.In that case get yourself a set of channel lock(slip joint) pliers big enough to grab it.Next time don't tighten it with the wrench.Hand tight only.
If I'da known it would last this long,I'da taken better care of it.

There are tons of tools available that are for exactly this purpose: to remove rounded-off bolts.

If you don't want to spend a few dollars on a special tool for this purpose, you can sometimes get away with using vice grips. Failing this you can use a small Dremel tool or even a file to create a couple flat edges on the rounded bolt, then grip those with the vice grips.

I suggest that you go to your nearest Honda dealership and order or acquire a replacement bolt with crush washer prior to getting the old one out.

By all means get a replacement bolt. I would add that you can get a replacement bolt with a magnet in the end to help keep metal shavings from circulating. ONLY thing to watch out for is that you don't have any moving parts close behind the bolt. Most sumps and lower pans don't. I use two on my Roadstart 1600. One for the engine pan and one for the oil sump.
A day, month or year, it's all subjective when your riding!

That's why I never use a 12 point socket or a box end wrench....always use a 6 point wrench to prevent it from slipping and rounding the bolt head

Definitely pick up a 6 point box end wrench. You will also need this to remove the final drive fill cap.

heres a tool you might not have considered using........a plumbers basin wrench...... ... sin+wrench

i had to use one once on a oil pan drain bolt that was partially rounded out and it worked great. it grabs on one side of the bolt much like a channel lock tounge-in-groove pliers and holds tight while your turning it. something you might want to think about trying.
