You can use someone like OK!Shon to bid for you.
Their charges can be quite high though and you might get stung for import tax, though this might happen no matter who posts it to you.
I bought a PGM-IV over a while back, the PGM itself closed at 25000 yen (£160) but by the time it left Japan it had cost me £234. I was lucky with this one as it got delivered to my door without import duty, but that would appear to be luck of the draw. If Parcelforce had held it I'd have had about £50 duty and charges to pay
Including my costs of then fetching it from the Parcelforce depot it could have then cost around £300. More if I'd had it sent over via airmail.
