Varanasi, Sept 13 (ANI): A group of Japanese tourists visiting the temple city of Varanasi suggested that the collective effort of the residents will help the presently littered city become clean and tidy. This group travelling from Patna to Varanasi felt that the filth in Varanasi needs to be cleared off at once. One of the tourists, Aijwa, travelling with the group, said that the residents should not allow their city to be littered. Prime Minister, Narendra Modi, recently visited Japan and signed a Memorandum of Understanding (MoU) with his Japanese counterpart Shinzo Abe. As a part of this MoU, Japan has agreed to work towards the heritage conservation and modernisation of Varanasi. The Tourist guide traveling with this group, Santosh, said that his guests were very unhappy with the filth they saw all over the town.
