Matsumoto Travel Guide: Japan's Black Castle & the Gateway to the Alps

Matsumoto sits in a mountain basin in Nagano Prefecture, two and a half hours west of Shinjuku, and its castle keep is the reason most people come: black lacquered walls over a water-filled moat, one of only twelve original keeps left in Japan and one of five ranked as National Treasures. The town around it is compact, walkable, and better than its reputation as a day trip suggests, and the Japan Alps start where the streets run out.

Matsumoto

Matsumoto is a castle town in the Nagano mountains built around an original 16th-century keep, with a frog-themed shopping street along the old riverbank, white-walled merchant storehouses, and horse sashimi as the local specialty.

Matsumoto Castle was finished in 1593 and 1594, and unlike most Japanese castles it is genuine rather than a postwar concrete reconstruction: the keep still has its original wooden interiors and stonework, which is why it carries National Treasure status alongside four others. It is a hirajiro, a castle built on flat ground rather than a hill, so the defense had to come from the water, and the moat still doubles the black keep in its reflection from the red Umesawa footbridge. Inside, the stairs between floors are ladder-steep, worn, and in places pitched near 60 degrees, and the sixth floor opens onto slit windows that frame the Alps in clear weather. The black lacquered cladding gets the castle called Karasu-jō, Crow Castle, though the castle's own management office points out that no historical document uses the name. The last structure added was the Tsukimi Yagura, the moon-viewing turret built in 1633 and 1634 under Matsudaira Naomasa, an open, red-railed room with no arrow slits at all, added for entertaining the shogun in peacetime.

The town has more to it than the keep. Nawate-dōri runs along the old bank of the Metoba River and is known as Frog Street, lined with about fifty small shops and stalls selling frog-themed everything; the name comes from the frogs that filled the riverbank until a typhoon in 1959 drove them off for good. One street over, Nakamachi keeps the white-walled, black-latticed kura storehouses of the merchants who once traded here, now craft shops and coffee. Matsumoto is also Yayoi Kusama's hometown, born here in 1929, and the Matsumoto City Museum of Art carries her work along with polka-dotted sculpture out front. The mountains are the other draw: this is the standard staging town for Kamikōchi and the Northern Japan Alps, and the last stop with a proper station, a supermarket, and a bed before the buses head up the valley.

Where to take photos

Matsumoto Castle — an original keep from 1593 and 1594, a National Treasure, black over a moat, with near-vertical internal stairs and Alps views from the top floor.
Tsukimi Yagura — the moon-viewing turret of 1633 and 1634, a red-railed room with no defensive slits, built purely for entertaining.
Nawate-dōri — Frog Street along the Metoba River, about fifty shops and stalls, named for frogs a 1959 typhoon chased away.
Nakamachi-dōri — the merchant quarter's white kura storehouses with black lattice work, now craft shops and cafes.

When to go

Early to mid-April, when the cherry trees inside the castle grounds open a week or two behind Tokyo's and the Alps still hold snow behind the keep. Late March, as in these photos, catches the first blossom with almost no crowd.

Where to stay

Stay between Matsumoto Station and the castle, near Nakamachi, which keeps the old town, the river, and the morning bus stops for Kamikōchi all within a ten-minute walk.

What to eat

Order basashi, raw horse sashimi, which Nagano eats more of than anywhere else in Japan, and a bowl of local sanzoku-yaki fried chicken if you want something cooked.

Tip

Buy the combination ticket for the castle and the Japan Ukiyo-e Museum if you have half a day, but go up the keep first thing: the stairs are single-file, and by mid-morning the queue inside the tower moves a floor at a time.
