This one has been discussed before. here and on other websites. The only way it makes sense & moves from the ASB area if there is a fundamental divergence in Japanese politics years earlier. I see several people here have suggested that as well.

Let's say Japan declares war in July 1941. The emperor makes a command.
Offers
1, naval support to protect the Pacific and Indian Ocean
Just denying German raiders and submarines ports for resupply would go far here.
2 infantry and ships to the Mediterranean
Now Im envisioning Japanese soldiers being gunned down by M34 as they rush ashore from Daihatsu landing craft. The Japanese army would find the Germans, or even Italians in a different class than the ill trained, equipped, and led Chinese they were used to. Now I'm recalling some hypothetical war games back in the day, of Japanese vs Germans. the players had to fudge the Japanese tactical ability a lot to compete.
3 zero aircraft to britan and Russia.
Japan was increasingly dependent on the oil it was getting from the US. Britain and its allies were sucking up every bit BP and Royal Dutch Shell produced. Circa 1940 70% of the worlds oil production was in or controlled by the US, and even a Depression era levels over half that consumed by US industry.
5 help on negotiating an end to the war in China
A long difficult negotiation. The KMT long range plans were: 1. Eject Japan from China. 2. Eject Japan from Manchria/Korea/Formosa. 3. Finish off the Communists. In the short run they might defer #2 if the Japanese help destroy Maos Communist state in the NW. But, in the long run Japans future depends on developing its own empire. The traditional view of the Chinese, and of the KMT government is at odds with that.
6 a long term lease on Netherlands oil
Japan is better off if this is not a sole source contract. Japan had over the long run been playing the global market. If it gets a affordable long term lease on the DEI oilfields, the the Dutch oil company gets screwed over the long run, or else Japan eventually gets stuck with a contract priced to high. US oil companies were ramping up their efficiency and at the leading edge in keeping their costs and customer prices competitive. Japan is better off going for flexibility
They had one up through the Great War. In various forms it last several decades, ending around 1922. Things were fine as long as Japan remained a client state. But, when it shifted to a expanding Empire model it was at odds with Britain. And most other European nations as well. Britan, France, Russia Italy, Portugal, and the US all had major economic interests in Asia. Any expansion of a Imperial Japan ran headlong into those. Thats why the US and Britain were so interested in ending the Russian Japanese war. Its outcome threatened their plans in Asia.
8 support to Russia in transporting supplies from USA to Russia.
Well, technically 'Russia' still existed, but the government that mattered here is that of the USSR. 1941-1945 Japan cooperated with the Soviet government is the transit of material from the US to the Soviet Maritime provinces and across the Far Eastern and Siberian provinces. Not a lot changes here.
Results would be peace in China. Short term oil from middle east Netherlands oil britan and Russia gain support at a critical time.
The first is important. In the long run there's not much difference in petroleum delivery contracts from the US, the DEI, Iraqi or Persia, or Poland (Yes Poland had a small oil field and industry.). Not really any change in view of supply to the USSR.
Japan could supplement The USSR or Britan with its industrial production. Ammunition, vehicles, & other sundry items to the users specifications would be useful.
