Brilliant lights

Exploration Stage: Angel Statue
From: Mayor
Description: People in town will be happy to know that the cherry trees in the Japanese Garden will be lit up. Use a lantern that is as bright as possible so that your view is not obstructed by fog. We have looked into various lighting tools, and it looks like we should use oil lamps in conjunction with them. Can you help me find one?
Completed: You have found a wonderful oil lamp! This will keep it burning all night long. Look at this copper container. This is where you put the flammable material. Let's get started on the preparations. We need to finish before nightfall.
