Conveniently located in front of Higashi Okazaki station (1-2 min walk). About 5 min walk to National Institutes of Natural Science (NINS); about 10 min to Okazaki Conference Center. Room is tiny but cozy, good enough to sleep.
There is a convenience store open 24/7 nearby but you can also order breakfast, which is decent quality. But if you go late in morning, most of good things may be gone. Just be an early bird.
Internet is available, both Wifi and Ethernet. But Wifi did not allow me to connect to POP (e-mai) server. Port 995 was closed. Ethernet worked for me. More
