Sending a suitcase home to the UK without me

How do I send a suitcase back home to the UK so I don't have to carry it around on my week to China on my way home?

Post.

@Firas That was the only choice that came to my mind. Personally I think it would be expensive and not worth it. I would lug it around. However there will probably be luggage services at the airport in China as there are in Japan where you could leave it for the week.

see "Sending Overseas". You can check the fare by yourself. If it is 20 kg, the fare is from 10000 yen to 30000 yen depending of the sending methods.

two services and very different pricing levels

sendmybag.com (fast service)

parcel2go.com (slower service but cheaper)

Japan post is cheap (if SAL or surface) but it's not just weight. The box/case dimensions are probably more important than weight, and don't allow for a very big box. I doubt most good sized suitcases would fit inside their dimensions limits.

Tom,

Thank you for your reply.

Japan post recommends to use not suitcase but an appropriate-sized cardboard box. The OP might better ask the nearby post office for the precise information.
