This charming town has long been a favored retreat, historically attracting aristocrats and literary figures seeking inspiration from its picturesque shores and pine groves. Today, it remains a haven for those looking to unwind, with its expansive, sandy beaches like Oiso Beach and Oiso Long Beach serving as the town's sun-drenched heart. Beyond the coastline, the landscape gently rises to reveal lush golf courses, including the renowned Oiso Prince Hotel Golf Course, and views of the distant Hakone Mountains.

Visitors will find a welcoming array of accommodations, with 11 hotels offering an average nightly rate of around $85, making a comfortable stay both accessible and inviting. Whether you're here to stroll the historic town center, feel the sand between your toes, or simply breathe in the salty air, Oiso promises a peaceful interlude from the fast pace of modern life.
Oiso's history is deeply intertwined with the sea and its role as a post town on the historic Tokaido road, connecting Edo (Tokyo) and Kyoto. This legacy is palpable in its relaxed, welcoming atmosphere. The town is famous for its stunning coastline, which has been celebrated in art and literature for centuries. While the provided list includes some notable attractions from wider Japan, Oiso's true fame lies in its local gems: the expansive Oiso Beach is a summer paradise for swimming and sunbathing, while the Oiso Long Beach offers serene walks. The Oiso Town Center retains a nostalgic Showa-era charm with local shops and eateries. The town is also a golfer's delight, with several prestigious courses set against scenic backdrops. Culturally, Oiso is a place of understated elegance rather than grand monuments, where enjoyment comes from soaking in the coastal vibe, visiting local shrines, and appreciating the carefully preserved natural beauty of places like the pine-clad coastline. It's a destination that rewards slow travel and an appreciation for simple, refined pleasures by the water.
The best time to visit Oiso is undoubtedly late spring (May to June) and early autumn (September to October). These seasons offer mild, pleasant temperatures, lower humidity, and minimal rainfall, perfect for beach activities, golf, and exploring on foot. Summer (July to August) is the peak season, drawing crowds to the beaches for swimming and festivals like vibrant summer fireworks displays over the bay. However, it can be hot, humid, and prone to occasional rain. The famous Oiso Beach is at its liveliest during this time. Winter (December to February) is the off-peak season, characterized by cool, crisp air and few tourists. While too cold for swimming, it's ideal for peaceful seaside strolls, enjoying clear views of Mount Fuji on good days, and experiencing the town's quiet charm. The weather is generally dry and sunny. For a balance of good weather and manageable crowds, the shoulder months of May and October are highly recommended.

Oiso is a compact town best explored on foot or by bicycle, especially around the beach and town center areas. Bicycle rentals are available and provide an excellent way to cover more ground along the coast. The primary public transportation hub is Oiso Station, served by the JR Tokaido Line. From here, you can easily reach major attractions; the beach is just a short walk or bus ride away. Local buses connect the station to various points, including the golf courses and more distant parts of town. Taxis are available but not as ubiquitous as in larger cities; they can be hailed at the station or called via phone. Ride-sharing apps like Uber are less common here. For airport transfers, Narita (NRT) and Haneda (HND) airports are both accessible via train connections through Tokyo or Yokohama, with the journey taking roughly 2-2.5 hours.
