Open
A gate with a lantern is open for you. That's convenient, since it's pretty dark out and you might not have seen the open gate without the lantern's help.

あ, ひら
None
This open gate is in the water though, so you'll need a kayak (かい) to get in. Luckily, you've been carrying your kayak with you just in case.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
