Ok checked the package. Its around 2100g, so if you add enough wrap, i'd guess 2500g (2,5k)

Shipping fees to California (had to pick up a state...) :

EMS (3 to 4 days) : 35 euros (4700 yen)
Economy Airmail (2 to 3 weeks) : 37 euros (5000 yen)
Airmail (up to 8 days) : 44 euros (5900 yen)

Cheapest one is EMS.

As for Estonia :

EMS (3 to 4 days) : 40 euros (5400 yen)
Economy Airmail (2 to 3 weeks) : 37 euros (5000 yen)
Airmail (up to 8 days) : 44 euros (5900 yen)

Its the same shipping fees except for EMS that cost a little more.
