Can Japan reach Dutch East Indies oil without Indochina?

If Japan cannot reach Singapore, can it still seize the Dutch East Indies' oil?

Reaching the oil becomes much harder without the Indochina-Malaya springboard; an advance through the Philippines would face stronger Allied support from Indochina and the Dutch East Indies.

A viewer asks whether Japan can still reach Indonesian oil if it cannot reach Singapore. Geography sets the constraint: without the Indochina springboard, the historical southern route is much harder to open. An advance through the Philippines remains possible, but Allied French Indochina and the Dutch East Indies provide additional positions from which to support the American defense. The oil objective remains strategically important while the route to it becomes more contested.
