As Urotsuki enters, the area is rather dark and dismal with sewer pipes below the path she is riding on. It is also raining, but Urotsuki can change that by using the Rainbow effect. Once used, a rainbow will appear over Urotsuki and the rain will stop. There is a big flight of stairs at the end of the path which will take Urotsuki lower down. She can get down faster using the Spring Effect to jump down from the left side of the stairs.
There is a waterfall on the next path that you can see Urotsuki through if she passes underneath it. The main area of the sewers has dark water with red hands coming out of it. At the end of one of the paths, there are two red creatures kissing one another. Occasionally, one of them will disappear and the other will be sadly opening and closing its mouth. There is also a blue head in the water and a shadowy plant-like creature in the background. As Urotsuki progresses, she will reach a ladder leading up to Japan Town.
If Urotsuki goes down to the bar in Japan Town and equips the Lantern effect, you can see that Urotsuki is able to go on the path with lotus flowers floating around it in front the staircase leading down to the bar. If she follows that path east, she will come to a room that has a staircase with statues of the deity from Marijuana Goddess World beside it. When Urotsuki goes up the staircase, it transports her to Rough Ash World. If she goes left, however, she will be transported to Monochrome Feudal Japan.
- On the top level of the sewers, just above the zig-zagging flight of stairs to the lower floor, is an inaccessible ledge with a large red object partially visible on it. This object is actually an enormous red hand which currently cannot be fully seen in-game through normal means.
