Japanese government officials have raided the offices of Vodafone subsidiary J-Phone as part of an investigation into price fixing involving new-style camera phones.
The Japanese Fair Trade Commission is understood to be investigating whether J-Phone prevented retailers from cutting prices on camera phones.
J-Phone's rivals, NTT DoCoMo and KDDI, have introduced their own picture messaging services which has increased competition in the market.
The operator confirmed that the raids had taken place, but said that it could not comment on the allegations while investigations were ongoing.
