Yamanashi Prefecture is a landlocked prefecture in the Chubu region of central Honshu, cradled in the Kofu Basin and ringed by mountains, most famously the northern slopes of Mount Fuji and the Fuji Five Lakes. Home to the Yoshida Trail, the most-used of Mount Fuji's four climbing routes, and to Japan's oldest and largest wine region around Katsunuma, Yamanashi pairs alpine and lakeside scenery with a proud viticulture and fruit-growing tradition, plus the jewelry and crystal-carving craftsmanship of its capital, Kofu City.

Beach safety
Hard-earned guidance — read this before you swim, especially if you’re unfamiliar with the coast.
Critical
Swim where lifeguards are posted and follow flag warnings — green is safe, yellow is caution, red means no swimming. Rip currents are the leading beach hazard worldwide.
Caution
Watch for tide changes and marine life — jellyfish blooms, sea urchins on rocky entries, occasional shark or stingray advisories. Don’t swim alone, especially at dawn or dusk.
Tip
Reapply sunscreen every 90 minutes and after every swim. Take shade between 11 am and 3 pm — the sun is harsher than people expect, even when the air is cool.
Practical
Keep valuables out of sight or back at the accommodation. Beach theft is a small-but-real risk at busy beaches; never leave bags unattended while you’re in the water.

When do the lavender fields bloom?
Lavender typically peaks from late June into July, aligning with the Fuji Shibazakura and lavender festival season in the wider Kawaguchiko area.

From the Ubuyagasaki Lakeshore, Lake Kawaguchiko editorial.
