Model Course #3 — Chiba Boso Peninsula Long Tour (For Riders Who Want More Adventure)
The moment the ferry horn echoes across the bay, you’ll know this is going to be a day to remember. The Chiba Boso Peninsula Long Tour takes you out of Kanagawa entirely — across Tokyo Bay by ferry, around the wild southern tip of the Boso Peninsula, and back over the Tokyo Bay Aqua-Line via the famous Umi-Hotaru rest stop.
Starting and ending at RIDE TOURISM in Shonan, this is the longest and most adventurous of our model courses — a full loop combining a sea crossing, coastal flower roads, a historic lighthouse, and a heavy dose of expressway riding. If you’ve already done Izu & Hakone and Tanzawa & Miyagase and you’re hungry for something bigger, this is the one.

⚠️ Important Notes Before You Ride
- This route isn’t technically difficult, but it’s long — heavy use of expressways (Aqua-Line, Boso area roads) and a full day in the saddle. Recommended for riders comfortable with extended highway riding.
- Best season: Spring & Autumn. Avoid summer weekends — the Boso coast and Aqua-Line get crowded and hot.
- Wind protection is essential on the ferry deck — Tokyo Bay can be breezy even on warm days.
- Fuel up before Kanaya — gas stations become sparse once you’re on the peninsula.
- On weekends, arrive at the ferry terminal 30–45 minutes early — sailings can fill up.
🏍️ Start — RIDE TOURISM (Shonan)
The day begins at RIDE TOURISM in Shonan. We’ll brief you on the route, check your bike is ready for a long day of highway and coastal riding, and send you off heading south toward Kurihama — the gateway to a completely different side of Japan.
⛴️ Stop 1 — Tokyo Bay Ferry (Kurihama → Kanaya)
Board at Kurihama Port and cruise across Tokyo Bay to Kanaya in just 40 minutes. Stand out on the open deck and feel the sea breeze — Mt. Fuji may even greet you on clear days. Bikes are handled by the ferry staff, so you can simply relax and enjoy the ride across the water before the riding resumes.
🏔️ Stop 2 — Nokogiriyama / Mt. Nokogiri (Optional)
Just minutes from Kanaya Port, Nokogiriyama greets you with dramatic stone cliffs carved by centuries of quarrying. Take the ropeway up for a bird’s-eye view of Tokyo Bay, or challenge the famous “Hell’s Peephole” — a terrifying cliff-edge lookout that’ll make your heart race as much as the ride itself.
🌸 Stop 3 — Boso Flower Line
Roll south along the coast toward Tateyama on the Boso Flower Line — a 46km coastal route selected as one of Japan’s Top 100 Roads. Both sides of the road are lined with wildflowers, especially golden fields of rapeseed in spring. On a clear day, you can spot the Izu Islands floating out in the Pacific.
🏛️ Stop 4 — Cape Nojima Lighthouse
At the southern tip of the Boso Peninsula stands the Nojima Lighthouse, one of Japan’s oldest Western-style lighthouses, built in 1866. The rocks below are dramatic, the wind is wild, and the views stretch endlessly across the Pacific. A perfect spot to feel small in the best possible way.
🗼 Stop 5 — Futtsu Cape & Meiji Centennial Tower
A striking pyramid-shaped observation tower modeled after a five-leaf pine. From the top, enjoy a 360° panorama of Tokyo Bay, Mt. Fuji, and even Yokohama on clear days. The cape juts into the bay like a crane’s beak — a truly unique landscape and a great photo spot.
🌉 Stop 6 — Umi-Hotaru PA (Sea Firefly)
Heading back via the Tokyo Bay Aqua-Line, don’t miss a stop at Umi-Hotaru — a rest area built on an artificial island in the middle of Tokyo Bay. The 360° panoramic views are breathtaking, especially at sunset. Grab a coffee, a local sweet, and take it all in before the final stretch home.
🏁 Final Stretch — Back to Shonan
From Umi-Hotaru, the Aqua-Line carries you back to the Kanagawa side, and from there it’s a comfortable highway cruise back to RIDE TOURISM in Shonan. By the end of the day, you’ll have crossed Tokyo Bay by ferry, explored the wild southern coast of the Boso Peninsula, and looped back via one of Japan’s most unique expressway rest stops — 250–300 km, almost entirely on highways and coastal roads, in a single unforgettable day.
🏍️ Cross the Bay. Ride the Peninsula. Come Home by Sea Again.
A ferry crossing, a historic lighthouse, a flower-lined coastal road, and Tokyo Bay’s most unique rest stop —
250–300 km of pure adventure for riders ready to go further.
