Swiss Movement vs Japan Movement
I had been looking at automatic watches in the past, and I was wondering if there is any difference between Swiss Movement and Japan Movement? Which is more accurate? Which is more reliable? I know there are many connoisseurs in here. Thanks in advance.

IMHO the Swiss are the proverbial masters of watchmaking.
They usually have the longest histories/heritages.
Japanese movements, at least to me, represent very good bang for the buck. They are usually well built/reliable (like Seiko for example), however not at all on the same level as their Chronometer certified Swiss brethren.
In short, I say go swiss.

There is swiss made and then there is Swiss Made.
Most Seiko movements are well on par with the majority of ETA movements.
Swiss In-house, is a completely different story though.

I understand for most collectors and anyone who knows something about watches; a true chronometer is one that is tested in Switzerland and certified "Swiss Certified Chronometers". Can't anyone, like the Japanese manufacturer, have their chronometers certified in Switzerland?

I beleive they have to be swiss. Just because they are COSC doesn't mean much. Lum-tec delivered me a watch that was more accurate than any other swiss piece I own including COSC certified pieces. A ton of the top watches of the world do not do COSC certifications and their quality usually far exceeds the COSC certification requirements. I would covet a watch with the Geneva Seal much much more.
Only 3% of Swiss Watch production is COSC certified
Over a million official chronometer certificates are delivered each year, representing only 3% of the Swiss watch production, a proportion that underscores the exceptional nature of a chronometer. To earn chronometer certification, a movement must not only be made from the highest quality components, but also be the object of special care on part of the finest watchmakers and timers during assembly

Rolex submit by far the largest number of movements to COSC followed by Omega SA, Breitling, TAG Heuer and Panerai. Breitling submit all movements for certification but other manufacturers only submit certain models.
The Japanese have largely abandoned the accolade, replacing it with in-house testing to a slightly more strict standard as with, for example, the Grand Seiko.
A good article on COSC:
The Watchery Luxury Watch Blog: My Luxury Watch is COSC Certified Chronometer. What does that mean?

In-house is another league. The japanese are doing some great work and I think we will be seeing alot more movements with ETA's slowly drying up due to the Swatch acquisition. Look for more Seiko & Miyota's in the near future. Timing is excellent for the most part on the higher enders..
I have a SMC 2824 (shanghai movement company) that keeps time within a second consistently..

The 6R15 in my Prometheus JellyFish is more accurate than most of my watches with Swiss movements. The two exception are a 7750 COSC and 9040 COSC. I would much rather have this movement than an ETA 2824, ETA2836, or SW200. All of which I have had plenty of over the years. My understanding is the 9015's are better yet.
