On the Yanaka Heritage Trail

I had a couple of free days whilst in Tokyo and was able to wander at leisure on the Sunday (3rd July). On browsing through the Lonely Planet guide to Tokyo, I found a section on walking tours that highlighted some earlier traditions and environs around Nippori, Yanaka and Ueno. So after breakfast I took the train on the JR Yamanote line towards Ueno. For convenience my academic hosts had suggested I use a SUICA charge card so that I didn't have to try and figure out fare stages indicated on the maps above the ticket vending machines. I found it convenient as it was accepted on all the train and metro services I used, but it doesn't provide discounts and so is not economical for large numbers of trips (see e.g. this helpful guide).

Still somewhat struggline with jetlag, I started dozing off on the train. Next thing I knew the train had stopped at Nishi Nippori so I jumped out of the carriage and exited the station, under the bridge and onto the western side. Once again I wasn't exactly sure of the route to take, so ambled along up an adjoining street:

According to a Japanese friend, the yellow sign means something like "Safety Street" - but we don't know if that's descriptive or prescriptive! Anyway, on I went and soon came to the corner of a park, which provides a pleasant natural environment with its shade very welcome at this time of the year.

This area is known for stray cats and we're not supposed to encourage them:

Perched on a small hill, Nippori and its surrounds have been attractive to settlers for many centuries. It's now a heritage trail, one of 23 designated historical walks in Tokyo.

Even today there are some good vantage points offering extensive views, which show carefully cultivated cultural areas merged into rambling urban landscapes:

The initial impression may be a bit disappointing - it may seem to lack overall planning (and made me wonder what kind of permission would be needed for development). However, on reading a little more about Tokyo's urban planning, I came across a plausible explanation which describes how the reconstruction of Tokyo after the Second World War was by necessity implemented at a neighbourhood level using the existing urban 'typology', covering the streets in rich areas and poor. Hence especially the populated inner city areas can appear as a whole rather higgledy-piggledy. I think this is conveyed well in a memo about urban development (Matias Echanove).

Along this trail one can find quite a number of temples and shrines dating to the Edo period and were (as far as I could make out) either Shinto or Buddhist. Many had connections with other more rural parts of the country, sometimes with connections to mountains. The following poster, for a Shinto shrine, is an example:

I know little about Shinto, and whilst sorting through my photos I've had to look things up. After a while I came to recognize a number of distinct features in common. For instance, in the poster you can see some jagged white strips of paper suspended from rope. You encounter these when passing through a Torii gate and shimenawa ring:

The zigzag strips of white paper are called shime 注連 or gohei, and symbolize purity. They look like lightning, which itself is regarded as holy (and, I expect, may be associated with insight). I saw some visual instructions as to the Shinto ritual for entering the gate: one passes through the ring three times - first moving round to the left, then the right, and then the left ring once more; at each stage, one bows before moving. Finally, one proceeds straight ahead to make an offering and a wish (for prosperity, health etc.). When making an offering one claps loudly to call the attention of the divine beings. There are many online sources of info on Shinto, such as a a shrine guide and Shinto symbols

Along the way, I bumped into two volunteers working on local history projects. They were carrying with them recording equipment and making a podcast for neoKITAKUMIN. Perhaps they interviewed someone at the 'Swiss chalet':

I then took a right turn down into Yanaka Ginza, a traditional shopping area with quite narrow streets.

Lots of little shops, many crafts on display, a good place for souvenirs

The dining places are unusual. I learnt via Google that the following is Iranian:

It was late morning, so I was actually having an iced coffee in a little cafe opposite. I had lunch later in an Indian restaurant owned by a friendly Nepali, who informed me he had arrived in Tokyo 16 years ago and now had 5 restaurants in the city. It had quite a mixed clientele:

Refreshed, I rejoined the trail and explored some Buddhist temples, including a few dedicated to Kannon Bosatsu (Bodhisattva Kuanyin):

Another Bodhisattva, who seemed to appear frequently was Jizo Bosatsu, who is especially a protector of infants. So parents traditionally make offerings for their own newly born.

Often there are 6 Jizo Bosatsus in a row, one for each of the realms of existence (often adorned with red children's garments, such as bibs).

Some of the wooden temple buildings - here at Kannon-ji temple - remind a little of structures in Thailand:

Not far away, outside another smaller temple, Choanji, I saw a peace pole with its message 'May Peace Prevail on Earth,' which originally came in an inspired moment to Masahisa Goi. They are now found all over the world and are very popular at interfaith gatherings.

It's not a large distance, but there are many interesting aspects, so it's best covered at a slow pace. I spent several hours in the area before accelerating towards Ueno and the Tokyo National Museum, to delve further into the cultural history of Japan.

Research Visit to Gakushuin University

Located towards the northwest of central Tokyo, Gakushuin is a private academic corporation that comprises schools and colleges as well as a university that currently has 9000 students. It is famous in Japan because of its historical connections with the Imperial Court. When I arrived a couple of weeks ago, I found the Mejiro campus spacious and verdent, surprisingly so given its centrality; I was informed that among the universities inside the JR Yamanote loop, it's the second largest after the University of Tokyo.

The present campus, like much of Tokyo, has seen many changes, but among the modern blocks there still remain a few of the older buildings, a little over 100 years old:



The modern multi-storey block on the right (East building no. 1?) obviously offers more capacity, but in the distance are some well-maintained old classrooms, cherished by staff and students even today. To the left is the former library building, now housing the Museum of History, graced by a venerable old tree in front of a small pool and foundation:


However, I wasn't here to be a tourist (although during my week's stay I did have a chance to wander), but rather to explore aspects of e-learning. The opportunity had arisen following earlier exchanges of ideas in the UK: in 2005, Oxford University Computing Services (OUCS) received a visit from Professor Yukari Shirota of the Department of Management, Faculty Economics, Gakushuin University. I arranged for her to give a presentation on some interactive software she had developed that guided students through the study of some topics in mathematics. The system's architecture was based on solution plans to word problems and delivered using an intelligent agent (animated by the Microsoft wizard).

Prof. Shirota is a computer scientist of long-standing - for instance, she co-authored an introduction to UNIX in 1984. During the past decade, Prof. Shirota has been developing e-learning systems to aid in the teaching of mathematics to her Management students. Inspired by George Pólya, her research has been focused on problem solving, invoking techniques in A.I. and especially visualisation, to help make sense of how the formulae and equations are used in word problems in Economics. I was particularly struck by her idea that A.I. might be able replicate the rhythm of instruction from teacher to pupil, quite similar perhaps to the rhythm of communication between a mother and baby. I hadn't come across anything like this thinking in the UK.

More recently, Prof. Shirota's research has concerned the provision of integrated tools that enable academic staff to create a range of online materials to direct students step by step in tackling certain types of questions, particularly in the field of bond mathematics. These systems are typically Web applications with scripts that invoke computer algebra systems such as Maple and Maxima to deliver step by step instructions. Some recent examples of this work are evident in overview of activities for 2011.

With regard to the financial mathematics, Prof. Shirota and her colleagues have used a conceptual approach based on entity-relationship diagrams to relate variables to formulae and equations. So the tasks of understanding may be characterised by being able to visualise and understand this map and its relations. How may that process be best aided online? In its entirety, the complete diagram is too extensive and detailed to show all at once, so any online implementation will need navigation - to focus on particular formulae and relations, but also to 'zoom out' and see the model as a whole. So does this suggest navigating it like, say, Google Earth or some other way based more closely on the relationships?

It's in addressing these considerations that I have been offering some input with my background in mathematics, somewhat distant now, and more recently e-learning and Web development, gained mainly whilst in the Learning Technologies Group at OUCS. Determining effective solutions is a multi-faceted task: its design, especially in terms of user interface, should be soundly rooted in principles of cognition. As I am not trained in educational psychology, I have to deal more with the nuts and bolts of the learning context itself, primarily in terms of the current and emerging technologies. In this regard, I'd say that whilst the emphases in pedagogy vary from country to country, the predominance of personally own computing devices has presented new variables to factor into the education at all levels. It's particularly this phenomenon, which I tend to call mobile and ubiquitous computing, that I was encouraged to explore ahead of my visit in the form of a survey paper on e-learning systems for mathematics, with particular reference to business and economics.

To give some structure in this rather broad landscape, I initially made reference to some recent features of e-learning in the UK. There's a strong focus on learner-centred education; within that I'm particularly interested in processes of deep reflection, stemming from the RAMBLE project I led in mobile blogging and learning environments. I'm not sure about the merits of focusing so much on individual predispositions, but I felt that the work on open educational resources and podcasting as a delivery mechanism was a useful vehicle to illustrate how learning has emerged from being concentrated in a classroom or workshop and flowed out into less formal environments. It was with this image in mind that I developed a thread to show how computer assisted learning for mathematics has similarly emerged from the laboratory into the open and is now squarely aiming at handheld tablet and multi-touch devices.

The paper, whose full title is 'Ubiquitous e-Learning: Designing Web Systems for Economics and Business Mathematics', has been published in Gakushuin Economic papers and is now available online - in HTML and PDF formats.

Arrival in Japan

This month I had the opportunity to spend a week in Tokyo (1-7 July), my first time in Japan. I came on a research visit kindly arranged by Professor Yukari Shirota at Gakushuin University. I'll describe the research aspect in a later post, but here I'll just share some initial impressions on my arrival.

Japan has a very distinct cultural identity; it's one of the few countries that retains - at least in many people's perception - a uniqueness that has persisted in spite of its immersion in modern industrialisation and particularly global markets and consumer products. It's famed for its etiquette and politeness and it was as though the whole trip was couched in such ethos from the moment I dropped off my bags at Heathrow, where I had a friendly conversation with the staff of Virgin Atlantic.

We know Japan as 'the land of the rising sun', which is a translation of Nippon. It is fitting in many ways; the heat and humidity in the summer months is quite palpable, certainly sub-tropical, feeling not much different from Thailand. (I feel sympapthy for 'cool biz' workers who have to trade in their jackets and ties for reduced air conditioning, with the government advising units to be set to a minimum temperature of 28 degrees. Even in a land used to construction and reconstruction, there's been a lot of discomforting changes, faced with admirable forbearance.) But it's particularly as the emergence of the hi-tech society, that the sun it such a resonant symbol. It wasn't long before I was struck by its manifestation in rail transport.

On arrival at Narita Airport, there are many options to proceed to the centre of Tokyo. With the aid of a Lonely Planet guide, I had perused various routes to my destination of Mejiro and settled on catching the fastest train service available, the Keisei Skyliner, which can whisk you into heart of the capital in under 40 minutes, followed by a trip on the circular JR Yamanote line. So after collecting my baggage (probably the shortest wait I've had), I bought a ticket for the Skyliner, complete with a seat reservation, another one for the local service, and made my way down to the platform. The train duly arrived:

As this is the terminus, the train is cleaned before boarding, but there is also a wait for something else: the repositioning of the seats. Just like synchronised swimmers, every passenger seat is rotated in unison, through 180 degrees to face the direction of travel. Once on the train, pre-recorded announcements are given in Japanese (in a singsong voice) and more regular US English. The driver(?) makes only occasional announcements to inform passengers of the location of toilets and where to find refreshments - not the buffet car, but vending machines!

My train was surprisingly not on time. There had been an incident on the line causing congestion, but I was in no hurry, and there was no visible response from the other passengers. I disembarked at Nippori station, (mis)fed my Skyliner ticket into a turnstile, plucked out the other ticket and after enunciating "Me-ji-ro" to a couple of station staff I found the right platform. Shortly before midday I emerged from Mejiro station, into broad daylight and my first steps on Tokyo soil outside the transport system!

Initially a little disorientated, I established my bearings once I spotted the Northwest entrance to Gakushuin University.

This made me feel I really had reached my destination. With the aid of a map and directions from the porter at the gate, I subsequently made my way to the Faculty of Economics, met Prof. Shirota, and was later shown to the guest accommodation.

Time for a bit of rest, before the preliminary discussions later that afternoon...
