6 automation & keepers listed for Japan
In ChainChoice’s published ranking order, from this category’s 7 providers: those whose terms exclude Japan are removed; naming Japan or a region that covers it counts the same, and those whose terms do not state it come last. Each chip names the basis: a dated check, a region listing, or the provider's own claim.
#1 for JapanTukTuk (Helium)#1 globallyProvider states broad availability An open-source Solana crank protocol: the buyer posts a task with a per-crank SOL reward and any anonymous signer may execute it, so firing is time-only, but the executor set, the due-condition and the failed run are all public chain state — and a task can return its own successor, keeping a conditional loop entirely onchain.
