Under the plans, which are due to be presented to the shadow cabinet today, the submarines would be retained as a "latent" threat which could be equipped with nuclear weapons if necessary. In the meantime the stealth submarines could be used to transport armed forces personnel across the World.
John Woodcock, a Labour MP and Trident supporter, said: "Aside from the question of why exactly this would be needed given the Astute class submarines already convey special forces, defence experts have pointed out that the so-called Japanese option is a red herring because it would break the non-proliferation treaty.
"You can't legally recreate the ability to make nuclear warheads once you've scrapped then and you can't claim to be a credible opposition if you want to spend billions on an underwater Trident taxi service for British troops. It is as if whoever keeps floating these barmy ideas is determined to make Labour a laughing stock."
Labour's defence review is being overseen by Emily Thornberry, the shadow defence secretary and a unilateralist. She replaced Maria Eagle, a moderate Labour MP and Trident supporter, in the role in a reshuffle last month.
Ms Thornbery's review, which will report in June, will also question whether the next generation of Britain's Trident nuclear submarines are fit for the future.
It will raise concerns that the development of "swarms" underwater drones may mean that by 2050 nuclear submarines are unable to hide from the enemy.
The Government is expected to hold a Commons vote on renewing Trident in March in a move that will put Mr Corbyn in direct conflict with members of his shadow cabinet.
Up to 130 Labour MPs will defy Jeremy Corbyn and vote to renew Trident, anti-nuclear campaigners have estimated – challenging the leader’s belief the majority of the party backs his position.
After analysing thousands of public statements, past voting records and private conversations with activists groups, Trident opponents believe a majority of Labour MPs support renewal.
The findings undermine arguments made by sources close to Mr Corbyn that despite opposition in the shadow cabinet he has the backing of most Labour MPs – as happened over Syrian air strikes.
At that vote Mr Corbyn was blocked from whipping MPs to oppose bombing by senior frontbenchers but eventually saw the majority of Labour MPs support his position.
It comes with the Labour leader, a lifelong campaigner against nuclear weapons, determined to change the party’s formal support for Trident.
His internal critics see the issue as symbolic for the party, given the effective Tory attacks which came when they backed unilateral disarmament in the 1980s, and are fighting any change.
Anti-nuclear campaigners are now targeting a cohort of 25 new Labour MPs they believe are swayable plus a further 30-40 other including “soft” critics of Trident they hope to win over.
