Identifying swung vase...

Hello! I've recently started to collect vintage art glass, and came across this large swung vase that I can't seem to identify.
It's about 14 inches tall, and very heavy. I have no clue if it's old or new... ive been able to at least semi-identify most other pieces I've found, but this one seems to be eluding me.
Thanks for any input!

 

Japanese, 1960s ish, I suspect.

 

If you are going to post more art glass here, be sure to always include a photo of the base. (I assume no signature anywhere on the base or side?)

It should make a nice addition to your new collection.

 

Thanks for the suggestion..! I researched Japanese glass and definitely seems to fit the scheme... heres some base pics. Just flat.. no markings.

 

The bases on older pieces usually show wear which can indicate how old they are. Plus seeing how the pontil is ground down or not can determine maker so even if you think bases may be unimportant they are to the glassies.
