How Japan might employ the I-400 class

Potential I-400 operations off Australia depend on first building the support network needed to sustain such distant missions.

Question

How might Japan employ the I-400 submarines?

Short answer

Possibly off Australia, but only after creating bases and logistical support for their long-range operations.

Notes

The Australian coast is suggested as a plausible operational area for the I-400 class. The submarine's long range and aircraft capability could make distant missions possible. The design alone would not suffice, because Japan would first need bases and a logistical network able to sustain the boats. The proposed employment is therefore a two-stage campaign rather than a raid improvised from home waters.
