ACAO FOREST is a 660,000-square-meter hillside garden above Sagami Bay, a recipient of the World Federation of Rose Societies' Award of Garden Excellence. Halfway down stands COEDA HOUSE, a stacked-timber cafe pavilion by Kengo Kuma that reopens at night as BAR COEDA. The grounds also hold a hilltop swing over the bay and Japan's largest bonsai. The garden blooms year-round, peaking with roses in May. This guide covers what to see and how to plan a visit.The Hillside Garden Above Sagami BayACAO FOREST is built into a steep, south-facing hillside above Atami's Sagami Bay coast. The site covers about 660,000 m² (200,000 tsubo) and holds 13 themed gardens, plus the Soga Sengen Shrine and the Tensho Japanese garden.Layout: Top-to-Bottom Garden WalkThe recommended route is to take the free shuttle bus to the top of the hillside, then walk down through the gardens to the entrance. The route turns each section into a different scene as the bay comes closer with each switchback. The walk takes 1.5 to 2 hours.ACAO ROSE FESTA: 4,000 Roses, 600 VarietiesThe signature display is ACAO ROSE FESTA, when the gardens hold 4,000 rose plants across 600 varieties. Roses peak from late April through early June each year. The rest of the year, the calendar shifts through tulips, sakura, and other seasonal flowers.Award of Garden Excellence RecipientACAO FOREST is a recipient of the World Federation of Rose Societies' Award of Garden Excellence: an international rose-society recognition awarded to gardens that meet sustained standards of variety, design, and care.COEDA HOUSE — A Kengo Kuma Pavilion Above the BayAbout halfway down the hillside, the gardens open onto COEDA HOUSE, a glass-walled cafe pavilion designed by Kengo Kuma, the architect of Tokyo's Olympic Stadium and the V&A Dundee in Scotland, and one of Japan's leading contemporary architects.CO + EDA: A Tree Where People GatherKuma's idea: build a great tree from small branches. Glass walls and mirrored furniture dissolve the pavilion into the Rose Garden, so architecture and garden resonate as one. The name COEDA layers CO (gather) + EDA (small branches), with the added meaning of people gathering beneath.Construction: 1,500 Alaska Cypress Pillars in 49 LayersThe structure is built from 1,500 short pillars of 800-year-old Alaska cypress stacked in 49 layers, the shortest 80 cm and the longest reaching 12 meters. Glass walls open the room to Sagami Bay.Cafe Menu: Building as MotifThe menu uses the building as its motif:COEDA stick cakes: modeled after the pavilion's pillars; flavors from Atami daidai (bitter orange) cheesecake to matcha, chocolate, and strawberryLavender lemon squash: house-made cordial from herbs and flowers; the cafe's most popular drinkBest Time to Visit COEDA HOUSEQuietest hours are weekday mornings; light reaches the back of the room from mid-morning onward. Cafe seats can fill on weekend afternoons.Things to Do at ACAO FORESTBeyond the gardens, ACAO holds a hilltop swing above Sagami Bay, the Phoenix Pine (Japan's largest bonsai), an outdoor art park, a Shinto shrine, and a herb-and-flower workshop.Garden Swing Above Sagami BayNear COEDA HOUSE on the upper paths, a wooden swing sits on a flat lookout. The seat faces directly out over the water. A single push feels like swinging into the sea.Phoenix Pine — Japan's Largest BonsaiNear the upper gardens stands the Phoenix Pine, ACAO's official designation as Japan's largest bonsai, named for the sweeping branch line that resembles a phoenix's tail. Bonsai is the Japanese art of cultivating miniature trees in shallow trays, a centuries-old discipline of patient pruning and shaping. Phoenix Pine works in reverse: a trunk and crown trained at full landscape scale, close to the ground.Land Art Park — Outdoor Artworks & Stamp RallyAcross the property, the Land Art Park holds many site-specific artworks by contemporary artists. The Art Stamp Rally maps a walking route through 10 selected pieces. Highlights include:"45LDK": a wooden roadside hut (Runner-up Prize, Kobe Rokko Meets Art 2024)"Mural for the Goddess of the Forest": painted on the stairs and entrance of Parking Lot 1, depicting the deity worshipped at Soga Sengen ShrineA stamp rally card at the entrance maps each piece.Soga Sengen Shrine Within the GardensSet within the gardens, Soga Sengen Shrine is dedicated to the goddess of cherry blossoms. The shrine fits ACAO FOREST, which was conceived as a cherry-blossom landscape. Within the forest stands a mirrored torii gate: the gate marks the boundary between the everyday and sacred ground, and the mirror invites a quiet moment of self-reflection as you pass through.cokage — Herb and Flower WorkshopNear the entrance gate, gift & workshop "cokage" sells accessories, blended teas, and seasonal pieces made from flowers grown in the gardens. The on-site workshop lets visitors blend their own essential-oil pieces, herbal sachets, or floral keepsakes. Check the official site for prices and reservations.Where to Eat & ShopFive venues across the property cover full-day dining and shopping.
