Seads Kasukabe

Tucked into Kasukabe in Saitama Prefecture, Seads is a diving shop run by a married couple, and that homely atmosphere is exactly the point — even first-timers can settle in without feeling nervous. It's a PADI 5 Star Dive Center with 2 PADI Instructors, offering safety-first training built on global standards of reliability, and it carries a proud record of zero accidents since opening 37 years ago.

Who it suits

Lessons and tours run in small groups, so you can ask what you want to ask and never get left behind. Female staff are always on hand, which means women can feel at ease even when visiting alone. Beginners and those returning after a gap are genuinely welcome — it's fine if you can't swim or feel a little unsure.

License courses are handled with care across classroom, pool, and ocean sessions, all easy to follow at your own pace. On offer you'll find PADI Scuba Diving, PADI Snorkelling, and PADI First Aid – EFR, plus equipment sales and scuba rental. There's an onsite classroom, free Wi-Fi, a retail shop, and parking for those arriving by car.
