One of the big questions when planning a holiday is how much to allow for daily spending. Japan has had the reputation of being expensive, but it is possible to travel comfortably at the budget and mid-range levels.
Approximate daily costs for one person are given for three travel styles; budget, mid-range and high. These costs cover accommodation, food, regular sightseeing such as museum and temple admissions, transport around cities and towns, and incidentals such as laundry and luggage services. Intercity travel, major sightseeing such as guided day tours and theme parks, or activities such as sushi making classes are not included.
