===Map Unlocking & Progression===
'''5-4''' is unlocked after clearing [[5-3]] HP bar.

To clear the map, the boss's flagship must be sunk 5 times.
*[[Support Expedition]]s are available on this map.

===Tips===
There are two main routes available to reach the boss: north and south. 
*North route contains {{Enemy/Link|Standard Carrier Wo-Class Flagship IV}} and {{Enemy/Link|Battleship Ta-Class Flagship}} with high evasion and accuracy.
**Node {{MapRoute|C|red}} can also contain 1-2 {{Enemy/Link|Submarine Ka-Class Elite}}, sometimes in Line Ahead. It is recommended to go Line Abreast against this Node (BBs and CVs can handle all Surface Enemies in the Node even in this formation), and bring [[OASW]] DDs to deal with the submarines.
**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 carriers, but will enter night battle nodes like in [[5-3]] against enemy {{Enemy/Link|Heavy Cruiser Ri-Class Flagship|Heavy Cruiser Ri-Class Elite|text=Heavy Cruiser Ri-Class}} and Late Model DDs.
**SPFs are highly advised for this route in order to obtain AS at the boss node, as no CVs are allowed.
**There is an LoS Check in {{MapRoute|M|blue}} to go to the Boss Node, requiring LoS ≥ 45 (Cn2).
***LoS Check is ignored if the fleet is '''Fast+'''.

*No matter which route is taken, {{Enemy/Link|Light Cruiser Tsu-Class}} will show up nearly everywhere in this map. Therefore, when using a composition with CVs and going north, it is recommended to use ones with high capacity slots, and place bombers only in the highest capacity slots to avoid all bombers getting shot down to 0 before 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.

*'''{{color|red|After clearing, the boss node will no longer contain {{Enemy/Link|Battleship Ta-Class Flagship}} nor {{Enemy/Link|Destroyer Ha-Class Late Model}}.}}'''
**When arriving via the '''southern route''', the boss node additionally will not contain {{Enemy/Link|Heavy Cruiser Ne-Class Elite}}
**This can make the southern route a viable leveling spot as transport node {{MapRoute|J|purple}} and boss node {{MapRoute|P|red}} each give a significant amount of experience

===Recommended Fleets===
<tabber>
|-|Middle route= 
Route = {{MapRoute|B|blue|E|red|H|purple|I|green|J|purple|M|blue|P|red}}
*2FBB/CA(V), 1CL, 3DD '''(Fast)''' (Quest {{Q|Bq6}})

*1FBB, 1CLT, 4DD '''(Fast)'''

|-|Advanced Middle route= 
Route = {{MapRoute|B|blue|E|red|H|purple|I|green|J|purple|M|blue|P|red}}
* {{color|red|'''"Torpedo Squadron"'''}}: '''1CL (flagship), 3DD, 2CLT'''
**This solution requires more advanced gears, and might be out of reach of new players. {{color|red|'''It is required to bring'''}} an {{CommandFacility}} FCF capable CL as flagship, preferably an {{Class|Agano|Kai+}}, equipped with:
***2 {{Med Gun}} [[Main Gun]]s, 
***1 {{Night SPB}} {{EquipmentLink|Prototype Night Zuiun (Attack Equipment)}} (having a 2nd Night Zuiun or 1 {{Surface Radar}} [[Surface Radar]] is advised if possible, to increase the trigger rate), 
***'''And'''  the {{IconText|{{CommandFacility}}|ETSCF}} {{EquipmentLink|Elite Torpedo Squadron Command Facility}} (preferably in the [[RE]]).
**The best comp for farming boss node '''without''' the need of [[Support Expedition]], having the highest pass rate thanks to the usage of [[ETSCF]] in case a ship got heavily damaged.
**The [[Evacuation]] mechanic of the ETSCF should be used if needed, as long as the routing is maintained.
***The boss routing is secured as long as '''the fleet LoS is higher than Cn2 45'''.
**Do note that the [[Night Zuiun]] will likely be shot down completely due to fighting under AI and the presence of {{Enemy/Link|Light Cruiser Tsu-Class|text=CL Tsu-Class}}, something negligible face to the potential double targeting of the Night Zuiun CI on previous nodes.
