Many SIGs and regional chapters are established, and they conduct various railfan activities. Once you become a JRC member, you can join those groups and attend their meetings and /or various events. Some conditions may be applied to join the group, and additional group/chapter dues may be necessary.

By attending their meeting and events, you can communicate with other club members. They may have through knowledge on a special interest or information on current topics to share with you. Thus your railfan activities become a lot more exciting.

For details on Special Interest Groups (SIG) and Chapters, please call JRC administrative office.
