12 miles (19 kilometers) outside of the heart of Kosai, you will find the Hotel Crown Palais Hamamatsu. The Hotel Associa Toyohashi is located 9 miles (14 kilometers) away. An alternative option is to make a booking at the Hotel Route-Inn Hamanako or the Daiwa Roynet Hotel Hamamatsu.
After spending time in in Kosai, put aside some time to look at Chubu's other attractions. Chubu is well known for beaches and mountains, and commonly visited destinations are ruins. In this section of Japan adventurous travelers might also try their hand at snowboarding, skiing and cross-country skiing.
Achi is 50 miles (82 kilometers) north of Kosai and is home to Achi Shrine and Chogaku-ji Temple. If you spend a night or two in Achi, be sure to check out the Yuruino Yado Keizan and Otogi-tei KOFU. For another option, stay in Nagoya Station, 50 miles (77 kilometers) to the northwest of Kosai, where you can choose from the The Westin Nagoya Castle and Hilton Nagoya. The Sky Promenade and Mode Gakuen Spiral Towers are other frequented points of interest to check out should you visit Nagoya Station.
Prior to leaving Chubu, you should certainly ensure you are able to join crowds watching some sport. Make your way to Nagoya Dome, found to the northwest of Kosai. Anybody wanting to find a Travelocity-listed hotel near the stadium can look at the Nagoya Tokyu Hotel or the APA Hotel Nagoya-Sakae.
