Boso Flower Line: A Drive Through the Flowers and a Walk to the Sea

Spring means the lighthouse, summer the flower-lined road, autumn the sea, and winter the canola flowers. Read the stories of the journeys I made on foot, by car and by motorcycle in each season.

At the plaza by Sunosaki Lighthouse in spring, a woman looks up at the white tower, holding back her hair with one hand. She wears a mint ribbed-knit top, a white cardigan, a miniskirt, and black ankle boots. Her smartphone hangs at her side in her other hand. A low white building stands nearby, and the sea stretches beyond a wall.

I Looked Up at the Lighthouse, Then Wanted to Linger by the Sea

One April morning, I drove along the Boso Flower Line and stopped at Sunosaki Lighthouse. Today I wanted more than a flower-lined drive; I wanted to see a lighthouse up close, right by the sea. When I parked and started walking, the breeze caught the hem of my cardigan, and my eagerness to see the water grew with every step.

From the plaza, a round tower rose above a low white building. It felt different from admiring the view from the road: here, the lighthouse stood right in front of me. As my eyes followed it toward the top, I found myself tilting my chin up. Just looking up at the tower I’d seen in photos made me feel that I was really here.

The wind blew my hair across my cheek, so I gently held it back with one hand. I had my phone in my other hand, which I kept lowered. I’d brought it out to take a photo, but I got so caught up in looking up at the tower that I forgot all about it. Before thinking about how to fit the whole lighthouse into a shot, I wanted to take in its height with my own eyes.

When I turned toward the sea, the water stretched beyond the low wall. I’d been watching the tower the whole time; now it was time to look into the distance. Standing in the plaza and feeling the breeze, I was already reluctant to head to the next stop. I love finding places like this along a driving route, places that make me want to stay awhile.

After leaving the lighthouse, I made another stop that day at Roadside Station Tomiura Biwa Club. I’d been looking forward to the loquat soft serve at Biwa Terrace. That first bite made me sigh with relief and brought the sea breeze back to mind; I wanted to take my time with the next bite. Something sweet after a view like that is a combination I love.

On the drive back, I kept thinking about standing there, looking up at the lighthouse with one hand holding my hair in place. Even on a trip where the road is the main event, getting out and walking gives me more moments to carry home. Next time I’m on this coast, I want to stop at places that catch my eye instead of just driving by.

A blue-and-white motorcycle travels along a straight stretch of the Boso Flower Line in summer, with low flower beds of marigolds on both sides. The woman riding it wears a white-and-navy jacket, jeans, black boots and a full-face helmet, and looks ahead with both hands on the handlebars.

A Morning Riding the Marigold-Lined Road

One July morning, I set off for the Boso Flower Line on my blue-and-white motorcycle. I had on a white-and-navy riding jacket, jeans and black boots. Watching the road through my visor, I could hardly wait to reach the stretch lined with summer flowers.

As I came onto a straight stretch, marigolds appeared in the low flower beds. Flowers lined both sides of the road ahead, giving it a different feel from the canola-lined stretch I’d seen in winter. Coming back to the same place in a different season changes the whole impression. Even with my eyes on the road, I could tell the road ahead was lined with flowers, and I felt my heart lift.

With both hands on the handlebars and my feet on the pegs, I rode on. Beyond the flower beds were trees; even along the coast here, the flowers and road filled my view. As I followed the white line into the distance, I was glad I’d come by motorcycle. I loved every minute of riding this stretch in the wind.

When I’d finished the flower-lined stretch, I parked to take a break and took off my helmet. While I was riding, I’d kept my eyes on the road ahead; once I stopped, I could take my time thinking back over the flower beds I’d just passed. I’d come here for the winter flowers; this time, I was enjoying the road on my motorcycle in summer. I wanted to tell someone about the difference, and I couldn’t stop smiling during my break.

Later, I stopped by Biwa Terrace at Roadside Station Tomiura Biwa Club. One bite of the loquat soft serve, and the coolness made me sigh in relief. A moment ago I’d been riding in the wind; now I was taking my time with ice cream. I’d been looking forward to both the ride and this snack today.

When I thought back on that summer road, it was the marigold beds that came to mind before the sea. The marigolds were different from the canola flowers I’d seen in winter, and I still remember the feel of riding past them. I thought I’d come for the flowers, but now I want to relive the ride itself all over again.

At Heisaura on an autumn evening, a woman in a lavender hoodie, denim shorts, opaque tights and black boots stands on the pedestrian side of a post-and-rail fence, looking out to sea with her phone lowered. Beyond low grassy dunes and a narrow stream, the sea and evening sky stretch out.

Before Taking a Photo, I Wanted to Watch the Sea at Heisaura a Little Longer

One October evening, after driving the Boso Flower Line, I parked and headed for the footpath at Heisaura. I wore a lavender hoodie, denim shorts, thick tights and black boots. Before heading home, I wanted to spend a little time by the water. With every step, the sound of the wind seemed to shift, and I found myself walking toward the sea.

As the view opened beyond the coastal grass, I could see the sea between low dunes. A narrow stream ran through a hollow in the sand, with waves rolling in beyond it. I hadn’t realized this landscape was just beyond the road I’d been driving. I stopped on the pedestrian side of the post-and-rail fence and took in the view stretching from my feet all the way to the sea.

I had my phone out, but kept my arm lowered. I’d come planning to take photos, but just watching the waves move made me want to stay a little longer. If I looked at the screen, I’d start thinking about how to frame the shot; for now, I wanted to look only at the sea in front of me. It’s nice to make room for moments like this on a trip, too.

The evening light touched the tips of the grass, and the shadows of the dunes slowly lengthened. I looked at the line where the sea met the sky, then back at the stream in front of me. I seemed to notice more than I had when I was looking for a place to take a photo. Even as I thought about when to head back, I kept watching the sea, telling myself I’d leave after the next wave.

During my break after returning to the car, I opened the loquat jelly I’d picked up as a souvenir at Biwa Club. One bite brought back the time I’d spent standing still by the sea. Instead of looking over my photos straight away, I wanted to enjoy this sweet bite first. I took my time, thinking back over the drive and the sea I’d walked out to see.

On the drive home, what kept coming back to me wasn’t the flower-lined road but the sight of myself standing by the sea with my phone lowered. I’d come hoping to take a piece of the scenery home, but the time before I took any pictures was what I found hardest to leave behind. I wonder what season I’ll walk here next. I’ve found another reason to look forward to Heisaura.

A red convertible travels along a straight stretch of the Boso Flower Line in winter, lined with canola flowers, pine groves and palm trees. The woman at the wheel wears a coat and scarf and holds the steering wheel with both hands; a lidded container of loquat jelly is secured on the passenger side.

After the Flower-Lined Drive, I Walked Down to the Sea

One February morning, I headed for the Boso Flower Line. Under my coat I wore a pale yellow sweater, with a warm scarf around my neck. I’d dressed for a drive with the top down. On the passenger side, I’d secured a lidded container of loquat jelly for my break. Today I was looking forward to both the flower-lined drive and a sweet treat.

As I entered the straight stretch along Heisaura, canola flowers lined both sides of the road ahead. With both hands on the wheel and my eyes forward, I watched the flower-lined road reach into the distance. Seeing flowers ahead while I was dressed for the cold made me happy and gave this drive a slightly different feel from my usual winter drives.

Where the pines grew in rows, the sea was just beyond them. When I think of a coastal road, I imagine the sea in view the whole way, but here the flowers and pine forest are part of the scenery, too. After finishing the drive and parking, I wanted to take the footpath to Heisaura’s shore. I was excited to walk toward the part of the view I couldn’t see from the car.

Before heading out on foot, I opened the lid on the loquat jelly. I could see the fruit through the clear jelly. The coolness of the first spoonful was a relief. Even in the cold season, a cool treat like this felt just right after the flower-lined drive. I didn’t rush the next bite, savoring it as I thought back over the road I’d just driven.

As I walked toward the coast, I could hear the wind differently from how it sounded inside the car. The drive among the flowers and the walk beyond the pines felt like two different experiences, even though both were part of the same Heisaura trip. I’d come just for the canola flowers, but by the time I headed home, I was wondering where I’d stop and walk next.

Highlights

About 6 km from Ito to Aihama

The stretch from Ito to Aihama is one of Japan’s 100 Best Roads. The flower-lined road and pine forest make this a drive worth taking. That long, straight stretch stayed with me long after I got home.

Heisaura Beyond the Pine Forest

The sandy beach and the black pine forest planted to prevent sand erosion are among Japan’s 100 Best White Sand and Green Pine Landscapes. After driving along the coast, you can slow down and walk to the sea along the footpath, enjoying the same place at a different pace.

Maebashi City and Mount Akagi, Gunma Prefecture Mount Akagi Lake Onuma, high atop Mount Akagi in Gunma, is close enough for a day trip from Tokyo, yet every time I arrive, I want to put off heading home. I still remember that first bite of smelt by the autumn shore.

Yorii Town, Saitama Prefecture Chūgen-daira Green Park Chūgen-daira Green Park, on a mountain above Yorii, covers 5 ha and has a sweeping view of town.
