===Tips===
You must sink the boss 5 times to clear the map.
*There are two main routes you can go to reach the boss: north and south. 
**North route is occupied with [[Standard Carrier Wo-Class]] Flagship IV, and [[Battleship Ta-Class]] Flagship, with high evasion and accuracy. They can potentially damage any of your ships on the way to the boss if not evaded.
***Node {{MapRoute|C|red}} also has a pattern with 1-2 Enemy SS, sometimes in Line Ahead. You are recommended to go Line Abreast against this Node (BBs or CVs can handle all Surface Enemies in the Node even in this formation), and bring [[OASW]] DDs to deal with them.
***There is an LoS Check in {{MapRoute|L|red}} to go to the Boss Node, requiring LoS ≥ 60 (Cn2).
**South route doesn't feature any enemy carrier, but you have to go through night battle nodes like in [[5-3]] against enemy [[Heavy Cruiser Ri-Class]] and Late Model DDs.
***SPF are highly advised for this route if you wish to obtain AS at the boss node, as no CVs are allowed.
***There is an LoS Check in {{MapRoute|M|red}} to go to the Boss Node, requiring LoS ≥ 45 (Cn2).
****It is ignored if your fleet is '''Fast+'''.

*No matter which route you take, [[Light Cruiser Tsu-Class]] will nearly show up everywhere in this map. Therefore, If you are using a composition with CVs and go north, you are recommended to use ones with high slots capacity, and place bombers only in the highest capacity slots on your CVs to avoid all of your bombers getting shot down to 0 by the time you reach the Boss Node.

*As with every map in World 5, [[Support Expedition]]s are available to assist with clearing. This can be especially useful for completing more difficult quests.
