Japan is one of those countries where the gap between expectation and reality is enormous — but in your favour. The temples are quieter than you imagined, the trains are more punctual than you thought possible, and the food is better than anywhere you've eaten before. The challenge isn't finding things to do. It's fitting them into the number of days you have.

Most first-timers land in Tokyo, ride the bullet train to Kyoto, and fly home thinking they've seen Japan. They've seen about 5% of it. This guide covers the full picture — when to go, what the weather actually does (it varies more than you think), the places that earn their reputation and the ones that don't, the food worth planning your route around, the cultural things that trip people up, the transport system that makes it all possible, and the connectivity setup that keeps your phone working from Narita to Nara.

Best time to visit Japan

Japan has four proper seasons, and each one changes the country dramatically. The short answer: late March to May (cherry blossom season into warm spring) and October to November (autumn foliage) are the two peak windows. But every month has something going for it if you know where to look.

• Spring (March to May): Cherry blossoms start in Kyushu in late March and sweep north to Hokkaido by mid-May. April is the sweet spot for Tokyo and Kyoto. Mild weather, 15 to 22°C. The most popular time to visit, and prices reflect it.
• Summer (June to August): Hot and humid across most of the country. 30 to 35°C with monsoon rain (tsuyu) in June and July. Hokkaido is the exception — comfortable and dry. Festival season (matsuri) runs through July and August.
• Autumn (September to November): The other peak window. Foliage turns from late September in Hokkaido to late November in Kyoto. Clear skies, comfortable temperatures, 15 to 25°C. Many repeat visitors consider this the best season.
• Winter (December to February): Cold in central and northern Japan. Tokyo sits around 5 to 10°C. Hokkaido and the Japan Alps get heavy snow — world-class skiing and onsen (hot spring) season. Fewer crowds everywhere except ski resorts.

Places that earn their reputation

Tokyo

A city of contradictions that somehow all work. Shibuya Crossing and the neon of Shinjuku are the photos you've seen. The neighbourhoods you haven't seen are where Tokyo gets interesting — Shimokitazawa for vintage shops and indie cafés, Yanaka for old Tokyo's wooden houses and temple cats, Koenji for live music and thrift stores. Tsukiji Outer Market is still the place for morning sushi (the inner market moved to Toyosu, but the outer stalls stayed). Budget two to four days minimum.

Kyoto

2,000 temples and shrines. You cannot see them all, so don't try. The hits: Fushimi Inari (the thousands of orange torii gates — go at 6am or after 5pm to avoid the crowds), Kinkaku-ji (Golden Pavilion), and Arashiyama Bamboo Grove (arrive at opening, 8:30am). The ones most tourists miss: Tofuku-ji for autumn foliage, Nanzen-ji for the aqueduct, and the philosopher's path walk between Ginkaku-ji and Nanzen-ji. Budget three days.

Osaka

Japan's food capital. Dotonbori is the neon-lit street food strip — takoyaki (octopus balls), okonomiyaki (savoury pancakes), and kushikatsu (deep-fried skewers on sticks). Osaka Castle is photogenic but the interior is a museum rather than an authentic castle. The real reason to visit Osaka is to eat. Locals call it kuidaore — "eat until you drop."

Hiroshima and Miyajima

The Peace Memorial Museum is one of the most important museums in the world. Give it time and emotional space. Then take the ferry to Miyajima Island — the floating torii gate, wild deer, and Itsukushima Shrine. The oysters grilled at the waterfront stalls are some of the best you'll eat anywhere. A day trip from Osaka or a comfortable overnight.

Mount Fuji

Visible from Tokyo on a clear day, climbable in July and August only. The classic photo spot is from Lake Kawaguchiko. The climbing season is short and the mountain gets crowded — Japan recently introduced crowd controls and an entry fee. If climbing isn't your goal, the Five Lakes region around Fuji offers spectacular views without the altitude.

Hidden gems most tourists skip

Kanazawa

Often called "Little Kyoto" but with a tenth of the crowds. Kenroku-en is one of Japan's three great gardens. The Higashi Chaya district has preserved geisha tea houses. The 21st Century Museum of Contemporary Art is one of the best in Asia. And the seafood — Omicho Market rivals anything in Tokyo. Two to three hours from Tokyo or Kyoto by Shinkansen.

Naoshima

An island in the Seto Inland Sea that's been turned into an open-air art museum. Yayoi Kusama's yellow pumpkin on the pier, Tadao Ando's concrete museums built into the hillside, and art installations in abandoned houses. Reachable by ferry from Okayama. One of the most unique places in Japan.

Yakushima

A subtropical island off Kyushu with ancient cedar forests that inspired Princess Mononoke. The Jomon Sugi hike takes 8 to 10 hours round trip to reach a 3,000-year-old tree. Shorter trails exist. Best from March to November.

Takayama

A mountain town in the Japan Alps with preserved Edo-period streets, morning markets, and Hida beef that rivals Kobe at half the price. The spring and autumn festivals (April and October) are among Japan's most beautiful. Base for visiting the thatched-roof villages of Shirakawa-go, a UNESCO World Heritage Site.

Koyasan

A mountaintop temple complex south of Osaka. Stay overnight in a Buddhist temple (shukubo), eat vegetarian monk cuisine (shojin ryori), and walk through Okunoin cemetery at night — 200,000 tombstones under towering cedars, lit by stone lanterns. One of the most atmospheric places in Japan.

Nikko

Two hours north of Tokyo. The Toshogu Shrine is one of the most ornate in Japan — the carved "see no evil, hear no evil, speak no evil" monkeys originated here. The surrounding national park has waterfalls, hot springs, and hiking. Spectacular in autumn.

Food: what to eat and where

Japan's food is reason enough to visit. Every region has specialties, and the baseline quality at even cheap restaurants is higher than most countries' mid-range.

Tokyo

Sushi (Tsukiji Outer Market for breakfast, or a standing sushi bar for value), ramen (Fuunji in Shinjuku for tsukemen, Ichiran for tonkotsu), tempura, and yakitori (grilled chicken skewers — Memory Lane in Shinjuku is the classic spot).

Osaka

Takoyaki, okonomiyaki, kushikatsu, and udon. Dotonbori for the experience, but the best food is in the side streets of Shinsekai and Tenma.

Kyoto

Kaiseki (multi-course seasonal dining — the highest expression of Japanese cuisine), matcha everything, yudofu (hot tofu, especially in Arashiyama), and Nishiki Market for street-level grazing.

Hokkaido

Miso ramen in Sapporo, fresh seafood in Otaru, soup curry (a Sapporo invention), and dairy — Hokkaido milk, cheese, and ice cream are the best in Japan.

Hiroshima

Hiroshima-style okonomiyaki (layered, not mixed), grilled oysters from Miyajima, and momiji manju (maple-leaf-shaped cakes).

Getting around Japan

Japan's transport system is the best in the world. That's not hyperbole — the Shinkansen (bullet train) network, local rail, buses, and ferries connect the entire country with military precision.

Japan Rail Pass (JR Pass)

A pass for unlimited travel on JR trains, including most Shinkansen lines, for 7, 14, or 21 consecutive days. Worth it if you're doing the Tokyo-Kyoto-Osaka-Hiroshima route. Not worth it if you're staying in one city. Prices increased in late 2023 — do the maths for your specific itinerary before buying. A Tokyo-Kyoto-Osaka round trip alone nearly pays for the 7-day pass.

IC cards (Suica / Pasmo)

Tap-and-go cards for local trains, buses, and convenience stores. Buy one at any station in Tokyo or Osaka. Load it with cash and tap through gates. Works across most of Japan. Apple Wallet and Google Pay versions are available for digital-first travellers.

Shinkansen (bullet train)

Tokyo to Kyoto: 2 hours 15 minutes. Tokyo to Osaka: 2 hours 30 minutes. Tokyo to Hiroshima: 4 hours. Smooth, quiet, and on time. Reserve seats during peak season. Green Car (first class) is worth it for long legs.

Domestic flights

Japan Airlines, ANA, Peach, and Jetstar Japan connect cities cheaply. Tokyo to Sapporo takes 1.5 hours by air versus 8+ by train. For Hokkaido or Okinawa, flying makes more sense than rail.

Rental cars

Only practical for rural areas — Hokkaido, the Japan Alps, Kyushu countryside. Japan drives on the left. Expressway tolls add up. An International Driving Permit is required.

Staying connected in Japan

Japan's public Wi-Fi has improved but it's still unreliable — limited to stations, convenience stores, and some cafés, with login screens that time out. You'll need data constantly: Google Maps for navigating the train system, Google Translate for menus and signs, Suica/Pasmo digital wallet, restaurant bookings on Tabelog, and WhatsApp or Line to stay in touch.

Frequently asked questions

What is the best time to visit Japan?

Late March to May (cherry blossom season) and October to November (autumn foliage) are the two peak windows. Both offer mild weather and clear skies across most of the country.

What is the best month to visit Japan?

April for cherry blossoms (Tokyo and Kyoto peak bloom), or November for autumn foliage. Both are peak months with higher prices and crowds.

How many days do I need in Japan?

Seven days covers the Tokyo–Kyoto–Osaka Golden Route comfortably. Fourteen days lets you add Hiroshima, Kanazawa, and the Japan Alps. Three weeks opens up Hokkaido or Okinawa.

Is Japan expensive?

It can be, but it doesn't have to be. Budget travellers can manage on $60 to $80 per day with hostels, convenience store meals, and a rail pass. Mid-range is $120 to $200. The yen has weakened significantly in recent years, making Japan more affordable than it's been in decades for foreign visitors.

Do I need a JR Pass?

Only if you're travelling between multiple cities. A Tokyo–Kyoto–Osaka–Hiroshima round trip nearly covers the 7-day pass cost. If you're staying in one city, it's not worth it. Calculate your specific routes at japan-guide.com before buying.

Is Japan safe?

Extremely. Japan consistently ranks among the safest countries in the world. Violent crime is rare. Lost wallets are returned. Solo female travellers and families with kids are comfortable everywhere.

Do I need to speak Japanese?

No, but a few phrases help. English is limited outside major tourist areas and hotels. Google Translate with camera mode is essential for menus and signs. The Japanese appreciate any effort — even arigatou gozaimasu (thank you) makes a noticeable difference.

Can I use credit cards in Japan?

Increasingly, yes — but cash is still needed for small restaurants, shrines, markets, and vending machines. 7-Eleven ATMs accept international cards. Carry ¥10,000 to ¥20,000 in cash as backup.

What network does the Japan eSIM use?

KDDI (au), ranked #1 for 5G download experience in Japan. 5G in cities and major towns, 4G LTE across all 47 prefectures including Shinkansen routes and rural areas.

How much data do I need for a Japan trip?

For a 7-day Golden Route trip with daily Google Maps, Google Translate, social media, and messaging, 5 to 10 GB is comfortable. If you're video calling or streaming, go Unlimited. Most tourists use 0.5 to 1 GB per day with maps and messaging; streaming pushes that to 2 to 3 GB per day.

Does the Japan eSIM work on Shinkansen?

Yes. KDDI has signal repeaters along all major Shinkansen routes. You'll get stable 4G LTE across most of the journey, with brief drops only in the longest mountain tunnels.

Is the unlimited plan truly unlimited?

Yes. The eTravelSim Japan unlimited plan provides full-speed 5G data with no daily cap, no speed reduction, and no fair usage limits. It's genuinely unlimited — not the 4 GB/day model used in some other countries.

Can I share hotspot from the Japan eSIM?

Yes, on fixed-data plans (1 GB to 50 GB). Hotspot is not available on Unlimited plans. If you're travelling with a companion, the 20 or 50 GB plan with hotspot is the practical choice.

When does the validity start?

When the eSIM first connects to the KDDI network in Japan — not when you install the QR code. You can install it at home before your flight and it won't start ticking until you land and switch it on.

Is it better than pocket Wi-Fi?

For most travellers, yes. Pocket Wi-Fi costs $5 to $10 per day, requires airport pickup and return, and is another device to charge and carry. An eSIM stays in your phone, costs less per day, and works instantly on landing.

Last updated: July 2026. Visa policies, JR Pass pricing, and eSIM plans may change. Verify current details before booking.
