Aogashima — the Island Inside a Volcano

A green volcanic island 360 km out in the Pacific, with a smaller volcano nested inside its crater and a village of about 170 people — one of Japan's most remote and surreal inhabited places.

📍 Tokyo, Aogashima 💴 Paid ⏱ Multi-day

✨ Experience

The Hells of Beppu (Jigoku Meguri)

A tour of seven boiling, steaming, technicolor hot springs you absolutely cannot bathe in — cobalt-blue, blood-red, and one with crocodiles — where the only thing you soak is an egg.

📍 Oita, Beppu 💴 Paid ⏱ Half day

🛣️ Roadside

Choshi Electric Railway

A tiny, perpetually broke seaside railway at the eastern tip of Chiba that famously stays alive by selling rice crackers — a 6.4 km line of vintage carriages, cabbage fields, and cheerful gallows humor.

📍 Chiba, Choshi 💴 Paid ⏱ Half day

🦊 Animals

Japan Snake Center

A delightfully old-school research park in Gunma devoted entirely to snakes — hundreds of them, from rat snakes to vipers — where you can watch a feeding, hold a python, and meet the staff's scaly stars.

🛸 Oddity

🌲 Nature

Noboribetsu Hell Valley (Jigokudani)

A steaming red-and-ochre volcanic crater that fuels Hokkaido's most famous hot-spring town, watched over by cheerful demon statues who are basically the local mascots.

🛸 Oddity

Sessho-seki, the Killing Stone

On a steaming sulfur field in Nasu sits a legendary rock said to hold the spirit of a murderous nine-tailed fox — and which famously cracked in two in 2022, prompting half-joking fears the demon escaped.

📍 Tochigi, Nasu 🆓 Free ⏱ ≈ 1 hour

🌲 Nature

Showa Shinzan

A steaming red lava dome that pushed up out of a flat wheat field in the 1940s — Japan's youngest mountain, born in wartime and lovingly documented by the local postmaster who watched it grow.

✨ Experience

Tateyama Snow Wall (Yuki-no-Otani)

🌸 Spring

🛸 Oddity

Tendo, the Shogi-Piece Town

The town that carves about 95% of Japan's shogi (Japanese chess) pieces leans all the way in — giant chess pieces on the streets, shogi-shaped everything, craftsmen you can watch at work, and an April festival played on a board of costumed humans.

📍 Yamagata, Tendo 🆓 Free ⏱ Half day

🛸 Oddity

Tobu World Square

A theme park near Nikko where you tower like a giant over the whole world: 100-plus famous landmarks — the Pyramids, the Eiffel Tower, the Taj Mahal, Tokyo — rebuilt in flawless 1:25 miniature, peopled by 140,000 tiny figures.

📍 Tochigi, Nikko 💴 Paid ⏱ Half day

🛸 Oddity

A flower-and-amusement park in Chiba that is famously neither in Tokyo nor especially German — but redeems the name each winter with one of the Kanto region's largest and most beloved light illuminations.

📍 Chiba, Sodegaura 💴 Paid ⏱ Half day

❄️ Winter

🛣️ Roadside

Umihotaru

A five-story rest stop on an artificial island marooned in the middle of Tokyo Bay, exactly where the Aqua-Line highway stops being a bridge and dives into an undersea tunnel — shops, sea views, and a giant tunnel-boring cutter on display.

📍 Chiba, Kisarazu 🆓 Free ⏱ ≈ 1 hour

🍜 Food

Utsunomiya, the Gyoza Capital

The Tochigi city that eats more gyoza than anywhere in Japan — dozens of specialist dumpling shops, a friendly rivalry with Hamamatsu, and a beloved stone statue of a gyoza wrapped in its own dumpling skin.

📍 Tochigi, Utsunomiya 💴 Paid ⏱ ≈ 1 hour

🦊 Animals

Aoshima Cat Island

A tiny fishing islet off Ehime where cats outnumber the handful of human residents many times over — no shops, no hotels, no cars, just a sleepy harbor overrun by friendly felines.

📍 Ehime, Ozu 💴 Paid ⏱ Half day

🏛️ Museum

Meguro Parasitological Museum

A tiny, free, two-floor museum dedicated entirely to parasites — home to a preserved 8.8-metre tapeworm and a gift shop selling parasite keychains. Tokyo's most gleefully strange date spot.
