More than 100 people have gathered at Embassy of Sri Lanka in Tokyo to pray for the victims of Sunday's deadly bombings.
The embassy has set up a table in front of its building to accept condolences on Wednesday.
Sri Lankans, including students living in Tokyo, have visited the site to offer flowers and messages.
One woman said she was shocked to hear about the attacks. She also told NHK that some visitors to the embassy had lost relatives and friends. She said she felt heartbroken but expressed hope that peace would return soon.
The explosions at churches and hotels in Sri Lanka's largest city of Colombo and a town in the east have so far left 359 people dead and about 500 injured.
