Tokyo Stock Exchange MAINS (MArket INformation System)

There are two ways that you can receive market information concerning market prices on TSE's market. You can either receive the information directly through a line dedicated to transferring this information, or you can obtain the data indirectly from someone already receiving this information. In either case, you must complete a contract with TSE to use this information. (For information on companies providing similar services for use by individuals or computer terminals, please contact those companies directly).

Aside from this service, TSE also provides MAINS Mail, which delivers end of day data via e-mail.
