# Best electronic contract & e-signature tools, compared

> Electronic contract software replaces wet-ink signing and hanko with a legally recognised digital signature workflow: send a document, collect signatures, and retain the signed record with an audit trail. In Japan the market splits sharply from the global one — domestic tools charge a flat monthly fee plus a per-send charge with unlimited users, while DocuSign charges per user with a capped envelope allowance. That single structural difference usually decides the choice. Prices below are from each vendor's Japan pricing page.

## Buyer's checklist for electronic contract & e-signature

- Does your cost scale with headcount or with contract volume? Domestic tools bill flat + per-send with unlimited users; DocuSign bills per user.
- Do you need party-type (registered-seal equivalent) signatures, or is witness-type (contract-seal equivalent) sufficient for your contract types?
- How many people need to send? Seat caps matter — DocuSign's Standard and Business Pro stop at 50 users.
- Will your counterparties accept the tool? Brand familiarity genuinely reduces friction when asking a client to sign electronically.
- How does the signed record meet your retention obligations under the Electronic Bookkeeping Act, and is that verified with the vendor rather than assumed?
- Do you need SSO, operation logs or governance controls — and which tier are they actually on?

## Frequently asked questions

### What is the difference between witness-type and party-type electronic signatures?

Witness-type (立会人型) signing is performed via the service provider on the signer's instruction and is broadly treated as the equivalent of a contract seal; party-type (当事者型) uses a certificate issued to the signer themselves and is treated as closer to a registered seal. Party-type carries stronger evidentiary weight and costs more per send — GMO Sign charges ¥100 for a witness-type send and ¥300 for a party-type one. Which you need depends on the contract, so confirm with your legal counsel rather than defaulting to the cheaper option.

### Is DocuSign or a domestic tool better for a company operating in Japan?

It depends on where your counterparties are and how your cost scales. If most contracts are with Japanese companies and many staff need to send, the domestic tools' unlimited-user model is usually cheaper and lowers counterparty friction. If you sign across multiple countries or your partners already use DocuSign, one global standard is worth more than the per-seat premium.

### Which electronic contract tools have a free plan?

CloudSign and GMO Sign both offer one: CloudSign covers 1 user and 2 sends a month, GMO Sign's trial free plan 1 user and 5 sends a month. DocuSign's Japan storefront has no free plan — its entry tier is Personal at ¥1,333/mo billed annually (5 envelopes a month, 1 user) — but it does offer a 30-day free trial. Every free plan here is single-user, so they suit evaluation or the occasional contract rather than a team where several people send.

### How current is the pricing shown here?

Each tool's price comes from that vendor's own Japan pricing page, and the date we last checked it is printed on the tool page next to the source link. Compare on two numbers, not one: domestic tools charge a flat monthly fee plus a per-send charge with unlimited users, while DocuSign charges per user with a capped envelope allowance, so a monthly fee alone will not tell you which is cheaper for your contract volume.

### How can AgentDoor help choose an electronic contract tool?

Instead of booking a demo with each vendor, you describe your requirements once — monthly contract volume, how many people send, whether you need party-type signatures, retention obligations — and AgentDoor's buyer agent interviews, in parallel, the matching vendors that have opened a door on AgentDoor, returning a shortlist with fit, indicative pricing and compliance answers. A tool on this page is included only if its vendor has opened a door.
