Several locations in Kanagawa Prefecture are worthwhile for birding:
Lake Miyagase, Kanagawa Prefecture
Southwest of Tokyo, about an hour by express train and another 45 minutes by bus, lie the thickly forested Tanzawa Mountains. On the northeast side is a reservoir known as Lake Miyagase (Miyagase-ko). The lake lies within the Aiko District of Kanagawa, between Sagamihara and Atsugi.
It offers views of the Tanzawa Mountains, including Mt Hiru. The lake was formed following the construction of the Miyagase Dam, to provide a source of drinking water for the cities of Yokohama and Tokyo.
Within the Tanzawa range are several lakes, and one in particular that is visiting is Lake Miyagase. It is easily reached by bus from Hon-Atsugi Station, which is on the Odakyu train line from Shinjuku, in central Tokyo.
The area is well-known as one in which to search for Crested Kingfisher and Mountain Hawk Eagle.
The lake and surroundings are a popular destination during the winter months for local photographers who go there to take photos of Long-tailed Rosefinch, Daurian Redstart and an assortment of buntings. Small numbers of Japanese Accentor also occur here in winter.
On a fine day, the blue bridge over the Hayato River attracts a small crowd of dedicated eagle photographers, and anywhere in the surrounding forests, the eternally elusive Copper Pheasant can be found.
Directly east of the bus stop – about a 10-minute walk – is an open park-like area with a small lake which attracts various ducks as well as Grey Heron and Great White Egret. Along the streams look for Brown Dipper and Common Kingfisher, and in the open grassy areas where there are small trees or bushes, wintering Bull-headed Shrike and Dusky Thrush can be found.
The main area to check is the Hayato-rindo (forest track) which is closed to ordinary traffic. This is where the photographers can be found, staking out their subjects, and the track runs alongside the lake. From the vantage points look for Western Osprey, Little Grebe and, during the winter, Mandarin Duck.
It is about 5 km from the entrance to the blue bridge, so it is a good idea to carry your lunch and something to drink to make it possible to eat a picnic along the way while watching for Crested Kingfisher and Mountain Hawk Eagle.
Early on summer mornings (May, June, July) Miyagase's forests are alive with the morning chorus of birdsong including those of: Blue & White Flycatcher and Narcissus Flycatcher, Japanese Thrush and Japanese Grosbeak, and also the mournful song of the White-bellied Green Pigeon.
Public Transport details: The bus departs from the north side of Hon-Atsugi Station, from bus stop #5 (in front of the Lawson convenience store). The destination is Miyagase, the final stop of the #20 bus.
From Miyagase, the last Kanachu Bus of the day leaves just before 2000: most buses depart at 10 minutes to the hour (17:50, 18:50, 19:50). There are toilets by the bus stop, but no facilities once you are beyond the entrance of the forest road.
The entrance to the Hayato-rindo can be found at map reference: 35.525193, 139.222435, while the blue bridge over the Hayato River can be found at map reference: 35.520043, 139.203595.
Futagoyama, Kanagawa Prefecture
The forested valley at Futagoyama provides an opportunity to look for a wide range of common resident Japanese birds, such as Brown-eared Bulbul, Japanese Pygmy Woodpecker and Varied Tit, but is best known in summer (from mid-May until early July) as the easiest site close to Tokyo to search for Japanese Paradise Flycatcher.
Directions: Take the train from Tokyo to Zushi. You can use either the JR Yokosuka line from Narita Airport /Chiba/Tokyo/Shimbashi/Shinagawa (and on to Kawasaki and Yokohama) to Zushi Station, or the Keihin-Kyuko line from Shinagawa Station to Shin-Zushi Station.
From either of the two Zushi stations it is probably best to take a taxi (about ¥1,000) to Kawakubo junction in Hayama town. The junction is on Route 311.
Kawakubo junction: http://diddlefinger.com/?ll=35.283852,139.589324&z=18&t=m
At this junction cross to the south side (you will see Vertex Garage on the opposite side). Walk along Route 311 in an easterly direction (against the flow of traffic) for about 50 metres, where there is a 7-11 convenience store (visible from the junction).
There are no toilets along the trail, so please use the ones at the 7-11 store, where you can also buy food/drink for a picnic.
At the side this store is a narrow pathway which goes for about 20 meters to the road behind (the same road coming from the direction of Vertex Garage). Turn left, and about 30 metres on the right side a small road goes off to the right (on the corner, there is a sign for Hearts cafe). Follow this road for about 500 metres (over the stream/bridge, past the NicoNico kindergarten and Hearts cafe (both on right side) to the entrance to Futagoyama.
Near to the entrance you will come to a sharp right-turn bend, then a stone mason's yard (left side), then another small bridge. There are some allotments on both sides here, and 50 metres or so further on, just by the muddy parking area under the tall cypress trees, you will come to a metal barrier across the track: this marks the entrance to the Futagoyama trail. Hung on the barrier is a big sign in red Chinese characters: Danger, keep out!
Entrance barrier: http://diddlefinger.com/?ll=35.279727,139.593637&z=18&t=m
Squeeze between the bars of the barrier and then wander the trail inside the forest between the hills. At one point you will walk under an overpass bridge (you can hear the vehicles passing by) and maybe 200-300 m further on you will likely find photographers. In late May or early June, if a nest has been located, these photographers will be standing in the trail with cameras, lenses and tripods set up.
One to three pairs of Japanese Paradise Flycatchers nest here each year and are the focus of considerable attention from local photographers who gather by the dozen when the pairs are nesting.
Otherwise, just wander along the trail as far as the wooden benches on a raised area above the stream. This is about 1.5 km from the entrance barrier. There is usually a pair of flyctachers around here too, but the best bet is to hang around where the photographers are.
To return to Zushi Station, you can walk (about 45 mins) or arrange for a taxi to come and pick you up at Kawakubo junction at a certain time. There is also a bus stop on the west side of Kawakubo junction but buses are infrequent, and there are none in the late morning and early afternoon. Buses go to/from JR Zushi Station.
Terugasaki, Kanagawa Prefecture
If you want to see White-bellied Green Pigeon, Terugasaki is the place to go!
In the early morning, flocks of pigeons fly out from the Tanzawa mountains, which rise up behind Sagami Bay, and drop in at this site. Here, they land on small rocks offshore and drink their fill of seawater before heading back to the mountains. Hot summer or autumn days are best, and most of the action is over by midmorning.
The rocks are just metres offshore, so the birds are close and excellent views can be had. It is a popular spot for photographers -- some fantastic shots have been taken as the pigeons suddenly take off vertically in front of breaking waves.
Other birds in the area include: Streaked Shearwater, Temminck's Cormorant and Blue Rock Thrush. There is a recent record of Arctic Tern here too.
Access: From Tokyo/Yokohama take the JR Tokaido line to Oiso station. Terugasaki, on the west side of Oiso port, is about a 20-minute walk to the southwest of the station. There are car parks nearby, but as the area is popular with surfers there is considerable congestion so it is easier to go by train and then walk.
The site is a few metres to the west of the port, on the south side of Route 1. Here, you can find a small waterpark with outdoor swimming pools and beside that there is a walkway that runs alongside the beach. Very close to the waterpark is the start of a long line of concrete tetrapods, which extend back to the port entrance.
Stand on the walkway and watch as the pigeons fly in and out in small groups.
