Local Tips
The 26-station railway through Chiba's rural interior is one of Japan's most charming branch lines. In spring, the trackside rapeseed and cherry blossoms create extraordinary views from the windows. The steam locomotive (SL) weekend service in spring is a bucket-list trip for train enthusiasts. Start from Oami Station on the JR Sotobo Line.

More in Chiba

Cape Inubosaki & Choshi Port
The easternmost point of the Kanto region — a lighthouse-topped cape where the Kuroshio Current meets the Oyashio Current, creating Japan's richest inshore fishing waters. Choshi Port is Japan's #1 sardine and saury landing port; the morning market sells fresh-grilled aji (horse mackerel) from open braziers on the harbour quay.

Kujukuri Beach
A 66km straight sandy beach — Japan's second longest — facing the Pacific Ocean on the Boso Peninsula's eastern coast. The consistent surfable waves, the wide open beach with no buildings on the ocean side, and the inoshishi (wild boar) that occasionally wander down from the coastal forest make this a wild Pacific experience.

Makuhari Seaside Park
A 85-hectare waterfront park on Tokyo Bay with the finest cosmos flower fields (autumn) and spring tulip gardens in the greater Tokyo area. The seaside promenade with distant Fuji views and the contrast of flower fields against the bay and Makuhari convention towers makes for surprisingly photogenic scenery in an otherwise suburban area.
