Fukushima & Aizu:
Castle Town & Onsen

A private hillside garden opened annually to the public from mid-March to late April. Plum, cherry, forsythia, magnolia, and weeping cherry bloom in sequence, turning the hillside into a patchwork of colour. One of Japan's lesser-known but genuinely spectacular spring sites.

Aizuwakamatsu Castle's grounds are lined with cherry trees that bloom late April. The red-roofed castle keep rising above pale pink blossoms is one of Tohoku's most photographed spring scenes. The castle is one of only a handful with its original lacquered roof tiles.

The Edo-era post town of Ōuchi-juku is surrounded by mountain forest. In late April, cherry blossoms frame the thatched roofs of the inns. The single road through the village — lined with restaurants serving Yamato-negi noodles — is at its most colourful in spring.

Iizaka Onsen town is ringed by cherry trees in late April. Soaking in a spring that has been running since 717 AD while cherry petals drift past — one of the most authentically Japanese experiences in northern Honshu.

The mountains surrounding Aizuwakamatsu are lush green in summer. The Aizu basin, ringed by volcanic peaks, offers clear mountain air and temperatures 5–8°C cooler than Tokyo. Ōuchi-juku's thatched roofs under summer foliage have a deep, saturated quality.

Aizuwakamatsu holds several summer festivals in July and August including the Aizu Teppo Matsuri (musket parade) and the Aizu Bon Odori. The castle town has a strong festival culture rooted in its samurai heritage.

In summer, Ōuchi-juku at 650m elevation offers a welcome cool escape from lowland heat. The thatched village in full summer green, with mountain streams and forest surrounding it, is as photogenic as any season.

Japanese onsen culture holds that summer soaking is restorative. Iizaka's hot springs — sodium chloride and mildly radioactive radon springs — are particularly prized for skin and joint health. A summer ryokan stay is unhurried and deeply relaxing.

The castle grounds are transformed by maple and zelkova in late October and early November. The red-roofed keep — already distinctive — becomes extraordinary surrounded by crimson and gold foliage. Peak colour: late October to mid-November.

The mountain road from Aizuwakamatsu to Ōuchi-juku passes through a spectacular autumn foliage corridor in October and November. The mountain post town itself is surrounded by crimson forest — one of the most complete autumn village scenes in Japan.

Autumn is the classic Japanese onsen season. Soaking in Iizaka's outdoor baths as the maple leaves turn and the mountain air cools is precisely the experience this region was made for. A private ryokan room with garden views in fall colour.

The Aizu basin in autumn is a landscape of golden rice fields against volcanic peaks. The harvest season fills local restaurant menus with new-crop rice, mountain vegetables, and mushrooms. A deeply satisfying season for food as much as scenery.

Ōuchi-juku in winter is one of Japan's most atmospheric cold-weather scenes. The Edo-era post road is buried under 1–2 metres of snow. Thatched roofs laden with snow, woodsmoke rising from the inns, the mountain forest white and silent behind. The village is far less visited in winter — you may have it almost to yourself.

Ōuchi-juku's Candle Festival (early February) is one of Tohoku's most beautiful winter events. Hundreds of candles line the snow-covered post road after dark, casting a warm glow over the thatched roofs and deep white snow. A profound winter experience.

Winter is when onsen are at their most essential and most beautiful. Iizaka's outdoor baths with snow on the ground and steam rising in cold air — this is the definitive Japanese hot spring scene. The contrast between cold air and hot water is extraordinary.

Aizuwakamatsu Castle under snow is a haunting, beautiful image. The red roof and white walls against a white landscape. The castle grounds are very quiet in winter — the samurai history feels most present when the crowds are absent.
