Japanese residents of London say they will continue to use the transportation system following the July 7 terrorist attacks -- but some are changing their travel patterns and considering the creation of emergency support networks in case of a repeat atrocity.

London has one of the largest Japanese expatriate communities in the world, and many living here expressed shock and sadness at the July 7 suicide bombings on three subway trains and a bus, which left at least 54 people dead and injured hundreds.

A number of the Japanese said they will continue to take the bus and subway as normal, despite police warnings the terrorists may strike again.

Security has been stepped up on the transportation system, but officials realize there is little they can do to stop a determined suicide bomber.
