130 years ago, Yokohama, where I live, was a small port town and farmland. But it also has an older history.
In the Nara era 1200 years ago, Tachibana county was founded and the government office was built on the hill near my home. The site was excavated in 1998 and built into the park, and I visited it by bicycle. I pedaled with Tokyo time travel map on the iPhone. Because I was not having fun while watching the current map, I displayed a map of 130 years ago and cycled on the old way. I displayed the present location with a GPS for an ancient map. It was a strange feeling.

There was an alley of residential areas now, but a stone signpost and a small shrine are left.

The remains were mere open spaces. The foundation stones were backfilled, Japanese buildings were made by wood and there was no trace.

Tokyo time travel map for iPhone was released last month. This application has former editions of maps of Tokyo going back every 20 years. Because it links with GPS, I can see the old map in the present location.

Shibuya was a farm village, and there was a waterwheel in the river beside me.

Today was the sixth practice challenge on Yabitsu Pass. Since previous week's time was very long, I was determined to improve it this time. Today's time was 51m50s, which was 45 seconds longer than my personal best, but three minutes shorter than last week's. Since the difference between last week and this was that I ate breakfast before cycling today, that could have been a possible factor of the long time. I lose pedaling power dramatically when I become the hanger knock. But it seems to begin gently before the hanger knock.

I took a GPS log using iTrail on iPhone every five seconds. The precision of the position looked fine, but it was not enough to measur the speed of the bicycle every five seconds.

107.29Km/Total 7h

I cycled to temple No.12, Syosan-ji temple. This part has the steepest slope of the Shikoku pilgrimage. The steep slope of here is called the "pilgrim toppler". I turned right onto prefectural road 43 from national highway 438 and began a steep slope of 10%. This slope continued all the way to Syosan-ji. If I had not changed into binding-pedals, I would surely have had to push my bicycle. However, this way I could ride even if it was less than 10km/h. At Syosan-ji, I met with an heir of a Japanese sweet shop. He was going on a pilgrimage with a GIOS' bicycle. He was touring and camping. He seemed like a very reliable youth. Surely, one day he will be able to make delicious sweets.

100.9Km/Total 8h I recorded a GPS log using iTrail every 180 seconds, but the battery of my iPhone lasted only about 3 hours.

Location information of the GPS is embedded in the photo which I photographed by using iPhone. I installed the add-on Exif Viewer on FireFox and checked up on the location information.

The seconds are displayed in decimal after the minutes; I calculated them. latitude 35" 25.66' -> 35" 25' 39.6 longitude 139" 13.17' -> 139" 13' 10.2

By using the "Longitude Latitude Search System" from the Japanese Geographical Survey Institute, I can display the topographical map of the place.

From the photo, you can pinpoint later where you had lost your way.
