Fender Japan Aerodyne Stratocasters Domestic

An ASTM SSH The M indicates Medium Scale

The domestic models fall into two versions the Special and the Standard the standard further subdivides into the normal scale 324mms and the medium scale 314mms indicated by M in the model name.
Model Timelines
The model designations changed from time to time but this did not necessarily mean the model had changed. MIJ guitars often have number linked to the release price in yen so as the price goes up they change the number. This happened a couple of times with the Aerodynes then they dropped the numbers completely so models available by year are

There will of course always be some overlap.

Fender Aerodyne Special 100DMC

Released in 2006 at 105,000 yen available in 2007 also. This was a higher quality guitar than the standard. See above table.

 
This is an Aerodyne Special in FLA note similarity to the Export SE Aerodyne Classic

I have had some correspondence from an owner asking about differentiating between the 100DMC and The Export Aerodyne Classic . These are cosmetically very similar but the Classic is Basswood so removing the neck should show the typical Basswood grain. Also the pickup covers should have the DiMarzio name on and if not you can tell DiMarzios by the end of the pole pieces

These are the distinctive DiMarzio pickups the scratch plate is not the original and the pickup covers are missing.

Fender Aerodyne Standard Full Scale length models.

The first of these the AST65 was released in 2004 at 65,000 yen only available in black. It looks to me like this is the same guitar as the Aerodyne version 1 released in the west.
In 2005 the price had increased to 68250 yen and new colours added GMB which is gunmetal blue and OCR which is a candy apple red. In 2006/7 it became the AST72 because of the price increasing to 72,000 yen and then in 2008 to the AST which it still is until production ceases around 2016. The change in name did not mark any change in specification although in 2009 or 2010 vintage white was added to the colour choices.
Left handed version first appeared in 2008 in black only, expanded into the full colour range by 2010.

The Fender Aerodyne Standard Medium Scale models

These are 314mms scale guitars (in the west this would be described as 24.7 inches) so only a slightly smaller scale than the full scale models. They have a narrower neck with a 40mms nut width and a flatter radius at 250mms. The first release was as the ASTM75/DH and DS models at 75,000 yen DH being SSH and DS SSS models. They later changed name as per the table above. Original release was in black, olympic white or gun metal blue. Candy Apple red was added around 2009. They have Dimarzio pickups described as Full range impact pickups DCS-3 DCH-3 possibly ceramics pictures not that clear. By 2010 however the reference to DiMarzio stops and they are referred to as J-Craft. I cannot find that these were ever available in a left handed version.
Update February 2017
The Japanese catalogue in 2016 now only shows The SSS model and the SSHM model. The SSS is available in Black, Gun Metal Blue or Old Candy Apple Red, the SSHM in Black or Gun Metal Blue.

Pickups
The pickups on the AST Standards are described as ST Vintage pickups which despite the name I believe are ceramics, perhaps someone who owns one could confirm. Strangely until 2010 the pickups on the medium scale models are Full Range Impact DCS3 (single coil) and DCH3 (humbucker) these are specially made DiMarzios available only on Japanese guitars.
