A DAY IN THE LIFE

A day at JSL

※ チーム編成・天候等により変更になる場合があります。

7:30

Arrival

Players check in at the stadium, walk through the day's plan, and start prep by team. Even first-timers settle into the rhythm of the day pretty quickly.

8:00

On the Field

Warmups, throwing, and personal prep to get loose. Coaches watch how each player is moving and help everyone shift into game mode.

9:00 - 11:00

Game 1

You take the field for your team's game of the day (one game per day). Tracking data shows your strengths and the work you can put in next — in numbers you can actually see. * Time outside your own team's game is yours to use freely.

11:30 - 13:30

Game 2

You take the field for your team's game of the day (one game per day). More reps at the plate, on the mound, and in the field. A new opponent each game means you sharpen the ability to adjust mid-game. * Time outside your own team's game is yours to use freely.

13:30 -

Lunch

Refuel and recover between games. A short break to reset before the afternoon program kicks off.

14:30 - 15:30

Level-Up Program

Sessions on data, conditioning, and life after baseball. Thinking about your future is treated as part of the work, not a separate thing.

16:00 - 17:00

Personal Practice

Whatever showed up during the day's games becomes the focus here. Coaches are on hand, and the last session is short but intense — one clear theme, full attention.
