Grand Mercure Lake Hamana Resort & Spa  

On the shores of Lake Hamana in Hamamatsu, this lakeside resort sits close to Hamanako Garden Park, Ulotto Museum, Maisaka-shuku Waki-Honjin and Arai Beach. A family-friendly base for lakeside walks, boat trips and eel-fishing adventures.

Rooms blend modern comfort with relaxed lakeside style — air-conditioned spaces with refrigerators, LCD TVs, safes and desks. Private baths feature shower/tub combos and deep soaking tubs; many rooms and public areas frame lake views. Expect a calm, spa-forward vibe with indoor and outdoor onsen baths.

Soak in indoor and outdoor hot springs, lounge by a lake-view pool, or hit the spa and sauna. Nights can be lively in the nightclub or karaoke room. On-site perks include a massage room, shopping, kids’ playroom, concierge, free self-parking and a complimentary train station pick-up. Wake up to lake-breeze mornings and easy access to boat trips and fishing.

A full business center and flexible meeting spaces total about 11,119 sq ft (1,033 m²), plus meeting rooms and a 24-hour front desk. Complimentary Wi‑Fi is available property-wide, with laundry and conference support on site.

Three restaurants, a coffee shop/café and a bar serve lakeside meals and local flavors — eel dishes are a regional specialty. All-inclusive stay packages are offered (note: lunch may be excluded and some activities may carry additional fees).
