Short answer: It depends. The cost of joining a flight club varies widely based on the club, its location, and the services it offers. Below are the most common expenses you can expect when becoming a member:

Initiation Fee A one-time fee paid when you join the club. In many cases, this is around 50,000 JPY or more.

Monthly (or Annual) Membership Fee A recurring fee required to maintain your membership. Some clubs charge monthly, while others bill annually. Prices vary significantly, ranging from as low as 112,000 JPY per year (about 1,000 JPY per month) to 300,000 JPY per year (around 8,000 JPY per month), or even higher, depending on the club's size, aircraft fleet, and facilities.

Other Costs (Not Part of "Joining" Fees) While these aren't included in the initial membership fees, keep in mind that flying also comes with additional costs such as aircraft rental and insurance. These expenses are separate from the club's joining fees and will vary depending on the aircraft type, the club's policies, and how frequently you fly.
