Frequently Asked Questions

What is JSL?

JSL is an open summer league built mainly for graduating high school players whose Koshien run came up short. The idea is simple — no one should be overlooked just because the bracket didn't go their way. Anyone eligible can join, keep improving, meet new teammates, and take a fresh look at what comes next.

Who can join?

Third-year high school students with baseball experience.

How much does it cost?

See the Entry page for current fees.

Does JSL help with what I do after high school?

Plenty of JSL alumni have moved on to college baseball, independent leagues, further study, or straight into work — and many tell us JSL helped open up paths they hadn't considered before.

Are the hotel and flight included in the fee?

They are not included. Please arrange your own lodging and transportation.

Can I get a refund if I cancel after payment?

Participation fees are non-refundable for cancellations made for personal reasons.
However, if the league is not held or in other cases due to the organizer, we will refund the fee less a set handling charge.

Can I take part even if I've retired from my baseball club?

Yes. Some players take part as a place for real-game experience and growth even after retiring.
