August is one of the most culturally significant months in the Japanese calendar. It's during this period that Obon — an annual Buddhist festival — takes place across Japan, drawing families together to honour the spirits of their ancestors through lanterns, dances, and graveside ceremonies.
Whether you're planning a trip to Japan specifically for Obon or are visiting for any other reason during the summer, this guide covers what the festival is about, what to expect, and why a SIMOVO Japan eSIM belongs in your bag before you board the flight.
What is Obon?
According to Japan-Guide, Obon is a Buddhist festival celebrated every year to commemorate the returning spirits of ancestors. To help guide loved ones who have passed away return to Earth, many Buddhists light floating lanterns and hang lights outside their homes, while offering food and dances in honour of those making their spiritual journey back.
Traditionally written as お盆, Obon takes place on the 15th day of the seventh month — though when that falls in practice depends on which calendar is observed. Japan has followed the Gregorian calendar since the late 19th century, but many regions continue to observe the lunar calendar for traditional festivals.
[tip title="Obon is observed in either mid-July or mid-August — check which applies to your destination"]When observing the solar/Gregorian calendar, Obon falls in mid-July. When observing the lunar calendar, it falls in mid-August. Most of Japan's major cities and tourist destinations observe mid-August Obon — but if you're travelling to a specific region for the festival, always confirm the local observance dates before you book.[/tip]
Obon is also frequently known as the Japanese Festival of the Dead — a chance for living people to offer gratitude to those who have passed on before them, whether recently or centuries ago. It's both a sombre occasion and a celebratory one, and its warmth and communal spirit make it one of the most memorable events a visitor to Japan can experience.
What to expect during Obon
The lighting and display of lanterns — whether outside homes or floating across rivers and lakes — is one of the most iconic Obon traditions. Families also visit cemeteries and grave sites to pay their respects, tend to headstones, adorn graves with fresh flowers, and in some cases build new shrines.
Obon isn't solely a private or family affair. Public events run throughout the festival period across Japan, and visitors are warmly welcomed to participate respectfully — lighting and placing lanterns, observing ceremonies, and joining the communal atmosphere.
[tip title="Watch for Bon Odori — one of the most joyful and accessible Obon experiences"]Bon Odori, or Bon dances, are public circle dances performed to traditional music during the Obon period. Communities come together in open spaces and temple grounds to dance in unison — a genuinely uplifting experience that visitors can observe and, in many cases, join. These dances vary by region, so you may see quite different styles depending on where you are in Japan.[/tip] [warning]Obon is a deeply meaningful cultural and religious occasion for Japanese families. If you encounter graveside ceremonies, private family gatherings, or processions, always observe from a respectful distance and avoid photographing without permission. Public events are open and welcoming — private rituals are not.[/warning]
Preparing for your Japan trip
Beyond passport, clothing, and budget, there's one more thing worth sorting before you travel to Japan: your data connection. Public WiFi is reasonably available in Japan's cities, but it carries real security risks — and relying on your home carrier's roaming rates for an extended summer trip is a reliable way to come home to an unwelcome bill.
[warning]Public WiFi in Japan — including at tourist sites, transport hubs, and festival venues — is not always properly secured. Unsecured networks can expose your personal data, passwords, and browsing activity to interception. A SIMOVO Japan eSIM gives you a private, encrypted mobile data connection throughout your stay, without any dependence on public hotspots.[/warning] [tip title="SIMOVO connects you to NTT docomo — up to 4G across Japan"]SIMOVO Japan eSIMs run on NTT docomo's network — one of Japan's largest and most reliable mobile operators — with up to 4G speeds across the country, including major cities, rural areas, and popular tourist regions. You land connected, with no SIM hunting or roaming activation required.[/tip] [tip title="Unlimited daily plans are available for heavy sharing and streaming"]If you plan to share lots of video content during Obon — floating lanterns, Bon Odori dances, temple visits — SIMOVO's unlimited Japan eSIM plans give you up to 5GB of data per day for up to 30 days, resetting every 24 hours. More than enough for a full summer festival stay.[/tip] [tip title="You can share your SIMOVO connection with travel companions via tethering"]Your SIMOVO Japan eSIM supports tethering — meaning you can share your data connection with other devices in your group, including family laptops and tablets, without needing to purchase separate plans.[/tip] [esim flag="🇯🇵" label="Japan" data="20GB · 30 days" price="£11" href="/products/japan" benefits="NTT docomo network · Up to 4G · Instant QR setup · No contracts"]Stay connected across Japan during Obon and beyond[/esim] [faq] [q]What is Obon?[/q] [a]Obon is an annual Buddhist festival in Japan celebrated to honour the returning spirits of ancestors.
