Visas & entry
Japan’s visa/entry rules depend on passport: citizens of many countries, including the US, Canada, Australia, the UK and most EU states, can usually enter visa-free for short tourism stays, while others need a visa in advance. Check Japan’s Ministry of Foreign Affairs rules for your nationality before booking; arrival through Narita or Haneda does not change the requirement.
Getting in
Getting around
Use trains confidently in metropolitan northwest Chiba and on the main JR corridors to Narita, Sawara, Choshi, Katsuura, Kamogawa and Tateyama. For a serious southern Boso trip, rent a car: coastal and inland sights are scattered, buses are thin, and there is no fast rail route across the peninsula. As of the November 2026 research snapshot, Isumi Railway is fully suspended and Kominato Railway is suspended south of Kazusa-Ushiku, with limited replacement buses; treat Yoro Valley, Otaki and the Boso Hills as car-first and check live JR/local-rail notices immediately before travel.
Money
Japan uses yen (¥). Cards work well at chain hotels, larger restaurants, stations and attractions, but carry cash for rural eateries, market stalls, small inns, buses and some local admission counters; an IC card is useful for urban rail and many convenience stores. Tipping is not expected and can cause confusion.

Entry rules change — verify visa requirements for your passport before booking this region.
December to February
Crisp, relatively quiet weather suits Narita, Sawara, Choshi and southern Boso; the south is mild by Kanto standards, with early daffodils and flower fields, but exposed coasts are windy and daylight is short.
Small coastal businesses may reduce hours or close midweek, resort towns can feel sleepy, and cold sea winds make beach time unappealing.
March to May
The best-balanced season for a first visit, with spring flowers, blossom season from late March into early April, and generally comfortable weather for towns and coastal driving.
Golden Week in late April–early May, Disney weekends and southern flower season raise hotel, ryokan and rental-car demand sharply.
June to mid-July
Humid, green and frequently wet, but viable for food-focused travel, temples and festival towns; rainy-season sardines are a Choshi specialty.
Rain undermines beach and hiking plans, while Narita and Sawara become crowded and accommodation tight during their July festivals.
Mid-July to August
Hot, humid and beach-oriented, with lively surf towns, swimming beaches and family attractions; afternoon storms and strong UV are routine planning factors.
Obon in mid-August tightens transport and coastal rooms, heat limits daytime sightseeing, and typhoon forecasts can disrupt a finely timed itinerary.
September to November
Cooler air, good surf and quieter beaches follow summer, while foliage generally arrives late—around late November into early December—but September and October are Chiba City's wettest months and remain typhoon-prone.
Storms can disrupt coastal trains, roads and ferries; Sawara fills early and road closures are extensive during its October festival.
Katsuura Big Hina Matsuri · Late February to early March; dates vary slightly each year. · Katsuura
Thousands of hina dolls, including a major display on the Tomisaki Shrine steps, make this normally quiet coastal town substantially busier; reserve local lodging ahead.
Narita Gion Festival · Usually early July. · Narita
Floats and dense crowds fill Omotesando; Narita accommodation books out and central access is slower than usual.
Sawara Grand Festival — summer edition · Usually the Friday to Sunday around July 10. · Sawara, Katori
A major float festival that transforms the canal town; expect road closures, heavy crowds and scarce rooms, so stay in Sawara only with an early reservation.
Sawara Grand Festival — autumn edition · Usually the second weekend of October. · Sawara, Katori
One of Kanto's standout float festivals; book accommodation well ahead and expect road closures and a town that is far busier than on ordinary days.
Eat Chiba as a coastal prefecture rather than a Tokyo suburb: working-port fish, shellfish, sardines and mackerel are the reason to detour, while southern Boso adds farm stands and early-season produce. Build meals around lunch in port towns and seafood dinners at a coastal ryokan; outside the urban north, do not count on late-night dining.
