Iritahama changes completely once the busy summer season winds down. At Aquaholic Iritahama we love autumn for its slower pace — the beach becomes quietly intimate, almost like having your own private stretch of shoreline. With only the sound of waves and the salty breeze, it’s the perfect place to unwind and recharge.

A calmer beach to reset and relax

Autumn is an off-peak season, so the crowds thin out significantly. If you prefer to avoid busy beaches, are traveling with small children, or simply want a peaceful walk on the sand, this season is ideal. Sit with a good book, stroll at dusk with someone special, or just watch the horizon — time seems to stretch here.

The water’s still warm — sometimes without a wetsuit

Although daytime temperatures cool a little, the sea often remains pleasantly warm. On sunny days you can swim without a wetsuit — in many years you’ll find comfortable swimming conditions through mid-October. The clear water at Iritahama is great for snorkeling and bodyboarding. At Aquaholic we offer free rentals of surfboards, bodyboards, snorkels and masks, so you can head straight into the water even if you arrive empty-handed.

Lower humidity and all-day comfort

As the humidity drops in autumn, both indoors and outdoors feel much more comfortable. Gentle sea breezes during the day and cool nights often mean you won’t need air conditioning. Mornings on the terrace with a coffee, watching the sunrise over the ocean, are a simple but lovely ritual we recommend.

Enjoy hot springs — autumn is perfect for onsen time

After a day in the sea, there’s nothing better than soaking in a warm bath. Aquaholic Iritahama features an open-air bath where you can relax right after your beach activities. The Shimoda area is also home to several onsen (hot spring) spots — from white-sand coastal baths to small local inns with outdoor tubs — making it easy to combine seaside fun with a restorative soak. In autumn, this combination — daytime sea, evening onsen — feels especially rewarding: the cool air heightens the comfort of the hot water, and a sunset or starry sky from a rotenburo (open-air bath) is pure magic.

Quiet beaches and romantic evenings

With fewer people around, the beach regains a peaceful, romantic atmosphere. Sunsets over the waves, footprints in the sand, and a slower pace make autumn a wonderful season for anniversaries, couple getaways, or relaxed family weekends. It’s also a beautiful time for photos and memories that feel a little more private.

Autumn at Aquaholic Iritahama offers a true sense of seaside luxury — the feeling of having the ocean almost to yourself. Spend sunlit afternoons enjoying the water and our free rental gear, then melt into a warm onsen as evening falls. After a soak, savor the fresh local seafood and unwind in comfort. If you have questions about reservations, parking, equipment rentals, luggage shipping, or nearby onsen options, please don’t hesitate to ask.  The whole team looks forward to welcoming you to Iritahama this autumn and helping you create a relaxed, memorable stay by the sea.
