I'm just copying this message here from a friend who had been in contact with the Japanese Customs:
Response from Japan customs :-) Dear Sir/Madam,
Thank you for your e-mail.
For temporary importation, if both of you and your vehicle will arrive at Japan by a ferry and will leave Japan within 1 year since entry, you can enjoy tax exemption system. When you will arrive at Japan, please make temporary import declaration with the customs form C No.5014. With this customs declaration, your vehicle can be exempted from taxes under the Customs Tariff Law, Article 17. Please note that if you will not re-export your vehicle within 1 year since entry, taxes which are exempted at entry will be imposed.
You can download this customs form from the following site.

On the other hand, if you can prepare with ATA carnet for your vehicle and you will re-export your vehicle within 1 year since its issue, you can take simplified import procedures with ATA carnet and taxes are exempted.
For more detailed information, please refer to the following site.

JAF For Visitors Bringing Vehicles with Carnet de Passages en Douane (JAF For Visitors Bringing Vehicles with Carnet de Passages en Douane)
On the other hand, if you will not arrive at Japan by a ferry or not prepare with ATA carnet for your vehicle, the importer has to make ordinary import clearance with required documents.

(Customs answer (FAQ))
Articles from 1102 to 1117 explain import clearance procedure.
In this case, you will be able to import them after duty/tax payment. In general, the duty rate on cars is FREE, but 8% of consumption tax will be imposed.
For just information, when you will use your vehicle on the public road, after import permit, you have to register your vehicle to MLIT, the Ministry of Land, Infrastructure and Transport.
For further information, please ask the MLIT directly.
