Located in Hamamatsu City, Shizuoka Prefecture, the Arai Barrier (新居関所) was a crucial checkpoint along the Tokaido during the Edo period. It is the only remaining historical site with preserved checkpoint structures, making it an exceptional place to learn about the transportation system and governance of the Edo shogunate. The reconstructed buildings of the Arai Barrier are primarily wooden structures. Inside, visitors can see inspection tools, ancient documents, and traveler records from the time. The layout includes the residence of the checkpoint chief and the women's inspection room, offering a glimpse into the past as if stepping back in time. The exhibition hall provides multilingual explanations in Chinese, English, and Japanese, making it an ideal destination for history and culture enthusiasts. After visiting the barrier, you can also take a stroll to the nearby old Tokaido street to enjoy the well-preserved historic townscape and riverside scenery. 📍Address: 1227-5 Arai-cho, Nishi-ku, Hamamatsu City, Shizuoka Prefecture 🚇Access: About an 8-minute walk from JR Arai Station 🕰️Hours: 09:00–16:30 (Closed on Mondays, or the following day if Monday is a holiday) 💰Admission: Adults ¥400, Elementary and Middle School Students ¥150

#FuriTabi Arai Barrier This is the remains of a barrier in Kosai City, Shizuoka Prefecture, and it's bigger than Kiga Barrier. It's a bit of a walk from the station, but it's fine if it's not raining. Only 7-8 minutes. There's a parking lot. You can also enter the tenement houses and the museum, where you can learn about the latest findings from excavations. Apparently, this is the only remaining barrier site. The admission fee is 400 yen.

I ate it at Sawayaka Kosai Hamanako store I got the summer vegetable set that is only available at this store! They grilled it on a charcoal grill for vegetables All the vegetables were sweet and delicious😋 I didn't know it was available only at certain stores I was glad I could eat it☺️☺️☺️ You have to wait, but Maybe it was because the weather wasn't so good that day It was a Saturday, but I was lucky and got in in about 45 minutes😊 #ShizuokaPrefecture #ShizuokaGourmet #Hamburger #SawayakaHamburger #Sawayaka #StoreLimited #SummerVegetables #CharcoalGrilled
