Itoigawa or Kishu?

[Wires_Guy_wires]

most likely pfitzer sea green

I second this.
Try rubbing a bit of foliage on soft skin on your wrist. If you get an itch, it's pfitzer.

Itoigawa, kishu and pure chinensis don't give me rashes. Everything that has sabina genetics in there does.

The picture of the OP is not a shimpaku juniper.

I think that's J. chinensis 'Sargentii'

The Juniperus chinensis saregntii is the "base" for shimpaku, see the text below (copy of this resources page).

Scale-leaf junipers: The adult leaves are mostly scale-like, in opposite pairs or whorls of three, and the juvenile needle-like leaves are not jointed at the base.

• Old World species:
  • Juniperus chinensis- Chinese Juniper. Native range is Japan, Korea, China, and Mongolia.
    • Juniperus chinensis subsp. sargentii- Sargent's Juniper; Shimpaku
      • Juniperus chinensis subsp. sargentii var. Itoigawa
        
        
      • Juniperus chinensis subsp. sargentii var. Kishu

Yes, but that's not how the American nursery trade labels their plants. J. c. 'Sargentii' is used to refer to a particular clone, which looks something like this:

Bad nomenclature, but that is what their tags read.

 

[ShimpakuBonsai]

Shimpaku is a variation of Chinese juniper (Juniperus chinensis, or Ibuki or Byaku-shin in Japanese).
Its Latin botanical name is Juniperus chinensis ‘sargentii,’ named after C.S. Sargent who identified it on Hokkaido in 1892.
