Hamarikyu Garden Guide

The centerpiece of Hamarikyu is the extraordinary Shioiri-ike — a large tidal pond directly connected to Tokyo Bay by sluice gates that open with each incoming tide to fill the pond with seawater. The changing tide visibly alters the water level throughout the day, shifting the garden's composition and the reflections in the water. Black-headed gulls and herons gather at low tide to feed along the exposed mudflats, while high tide floods the pond into a broad reflective surface that mirrors the surrounding pines and Shiodome skyscrapers. The pond is the only saltwater garden pond in Japan and is historically used for duck hunting by the Tokugawa shoguns.

Tidal information: check tide tables for Tokyo Bay to plan your visit. High tide creates the most dramatic reflection photos. Sunrise visits (when the garden opens at 9am) offer soft light on the water with fewer crowds. The sluice gates connecting to Tokyo Bay are visible from the pond's eastern bank.

The Nakajima Teahouse is one of Tokyo's most atmospheric spots for a traditional matcha experience — a graceful wooden structure built over the tidal pond on wooden stilts, connected to the garden path by a covered bridge. Visitors sit in the teahouse overlooking the pond and are served a bowl of whisked matcha green tea with a seasonal wagashi (Japanese confectionery). The combination of the traditional wooden interior, the seawater pond below, and the distant gleam of Shiodome tower glass creates an almost surreal juxtaposition of old and new Tokyo. Dating to the Edo period, the teahouse was restored and has served visitors since the garden was opened to the public in 1945.

Open during garden hours (9am–4:30pm last order). Matcha tea and wagashi: ¥700. No reservation required — wait time is usually 10–20 min at peak times. Seating is limited; arrive early or on a weekday for the best experience. The view from the teahouse over the tidal pond is among the most photographed sights in the garden.

Hamarikyu contains one of Tokyo's most extraordinary specimens of garden design: a grove of black pines (kuromatsu), including a single tree estimated to be 300 years old, that was carefully pruned and trained by generations of Edo-period gardeners into an elaborate horizontal canopy. These trees were among the most cherished features of the shogunal garden and survived the Tokyo air raids of 1945 — one of the few elements of the original Tokugawa garden still standing in its original form. The twisted, horizontal spread of the oldest pine is a remarkable example of Japanese horticultural craft, and the grove provides welcome shade during summer visits.

Located near the western section of the garden, easily reached from the main gate. The 300-year-old pine is clearly marked with a sign. Best photographed in morning light. The pine grove area is adjacent to the peony garden (botan-en), which flowers April–May and again in November.

Hamarikyu is renowned for its striking seasonal plantings that transform sections of the garden at different times of year. In late January–March, the rape blossoms (nanohana) carpet the inner garden paths in bright yellow — an extraordinary contrast against the grey winter sky and brown pine trunks. In April–May, the peony garden (botan-en) in the garden's southeastern corner comes alive with hundreds of tree peony cultivars in shades of pink, red, white, and purple. Autumn brings chrysanthemum exhibitions and the gradual color change of deciduous trees around the pond edges. The garden publishes an annual flower calendar on its website.

Rape blossom (nanohana): late January–March, no extra fee. Peony garden (botan-en): late April–May, ¥200 extra entry. Autumn foliage: late October–late November. The main garden ticket (¥300) covers all seasonal displays except the peony garden. Check the garden official site for current bloom status.

Hamarikyu has its own dedicated pier on Tokyo Bay, served by the Tokyo Water Bus (Tokyo Cruise) operated by the Tokyo Metropolitan Bureau of Port and Harbor. The pier is located inside the garden grounds, making a bay cruise from Asakusa a natural and scenic way to arrive. The 45-minute journey downstream from Asakusa passes under the historic Kiyosu and Eitai bridges, through the Sumida River estuary, and out into Tokyo Bay before docking at the garden pier. The route provides excellent views of the Odaiba waterfront, Rainbow Bridge, and the garden from the water. The reverse journey (Hamarikyu → Asakusa) is equally scenic.

Tokyo Water Bus: ¥1,020 adult one-way (Asakusa–Hamarikyu). Boats depart Asakusa Pier roughly every 40–60 min (check schedule at suijobus.co.jp). Garden admission (¥300) is separate from the boat ticket. Allow 45 min for the cruise. Return from Hamarikyu to central Tokyo via Shimbashi Station (15 min walk, JR/subway lines).
